[attach=8]Hello, I'm hoping someone can help me diagnose and fix a problem with an interference signal i'm getting on my 899.
It's signal that shows up on down scan, 2d sonar, and on the left side only of SI. It also shows up in all of the simulator views.
It is a line about a couple of feet down. It really never stops although I think it may decrease when I completely stop and drift a while. I need to do more testing there to be sure.
I have attached some pictures for reference, real and simulator.
Can anyone offer any suggestions??
Other than that, this thing is drawing some AMAZING pictures. Very happy with that. Upgraded to the XHS 9 HDSI 180T transducer.
Thanks for any help.[attach=1][attach=2][attach=3][attach=4][attach=5][attach=6][attachimg=7

My 899 unit doing the same thing. I thought it was my motor. Im going to raise up my motor to check for sure. its doing it in simulator too.

You might try testing without the livewell screen on...
I've seen many cases where the screen sticks out just far enough to reflect some of the left sound pulse...these instances have been remedied by installing a spacer block between the transom and the xducer bracket...
The SI beams reach all the way to the water's surface ...to overlapping at the bottom...
___________________________________
The line at the top of the 2d image is most likely just surface clutter...it's not the same obstruction reflection that is showing in the DI and the left SI...

Like Rickie says the SI beam may hit the surface, but it may also hit details on the stern even if they don't seem to obscure the beam. This is possible because the SI beam is not a single thin slice with sound as is shown in most sketches, it actually consists of a large number of thin slices which fill the angular space between the main beam and the plane of the piezo element. These sidelobes have much lower intensity than the main lobe has so they don't use to affect the image. This bundle with lobes act like one wide lobe that sometimes produces wide arcs around very reflective objects. If the stern has something very reflective on it, this can cause a line in the image similar to what jerklip has.
The image below show a simulation of the SI beams in a transducer with 113 mm long piezo element at 455 kHz. This is a way to show what the beams would look like if they were visible from above. The beams are calculated down to -50 dB which is rather low so the image actually exaggerates the influence from sidelobes.

Wow! Thank you to Rickey and Ricard. I have read this board for hours upon hours, and I am continually amazed at the generosity and interest to help by so many...and here it is again. Thank you both again. Rickey, I think you must have been spot on about the line in the 2D view being different from the returns in the DI and SI views. About two clicks on the surface clutter adjustment, and it was gone, at least sitting on the trailer. I'm going to see what happens when I remove the livewell screen. I read on another thread about adjusting the beam width also which I may try.
Rickard, that's a great explanation and illustration, and I actually get it.
Thank you both for the great technical information and advice.
I'll report back.
Al.river, would you please let us know what you discover also when you get a chance?
Thank you,
Curtis
-
WOW. Im sure my line is from my motor. I have my transducer mounted to a stern saver mount. the mount is 5/8 " so it sit me back some. it looked like was going to clear. Ill let yall know . thanks guys
-
Here is my latest input:
Removing livewell screen - no improvement.
Sitting dead still calm-almost gone, but not completely. Still there faintly (without the screen). But waaaaaay better. Tolerable.
Motor up, motor down, motor at idle, or revved, up or down, in gear or out of gear, not difference. (one exception to follow)
Narrowing the beam width on DI does give noticeable improvement on the DI view. But I don't want to be limited to narrow only.
Here is the exception mentioned above. Speed up. From 800-900 rpm to 1900-2000 rpm, it almost completely goes away.... in both I and SI. Almost completely gone. It's like I'm outrunning the cause of the interference.
It is definitely worse when in gear at idle speed.
Thanks y'all.

See if you can try reversing your drain plug on the boat so that it is inserted from the inside. That could be what you are seeing now.
You could try adding a spacer block between the transducer and the transom.
-
Jerklip, something I noticed is your drain plug. The handle or tip (used to tighten the plug) has a wide / flat profile. The flat portion is also facing your xducer.
Try to lower the profile by turning it till it is horizontal with the boat. Also try a lower profile drain plug such as a T handle or fold down model. See if this reduces what you are seeing as far as interference. Make a recording running in SI with the old plug AS IS (flat and facing the xducer) then do the same with it turned flat and one or both of the other model plugs. By pulling a screen shot of all three off HBPC you will really be able to see if it made a difference.
At this point it would be worth a shot. Post the px if you do this so we can see it as well. Hope this helps
-
X3 on the drain plug. That would be a fairly cheap test as well.
-
apologize about the re-post Greg...should had read farther down before posting.
-
Not a problem slabbacks – I didn’t even think about turning the drain plug handle sideways and testing. I was just focused on getting it totally out of the way by inserting it from the inside of the boat. I’ve had some experience in doing this but it was usually after the boat was launched and was starting to fill up with water… ::)
-
This is a fascinating discussion and it raises more questions in my mind than answers or suggestions ??? First one: does turbulence from intake screen, plug or something else cause sonar returns (this would perhaps explain less ghosting at higher than idle speed when boat lifts object from water or while not moving) ???
Second One: is the transducer pinging when in simulation mode.. if it is shut down then it seems it has to be an artifact in the units programming ??? If pinging it would have to be overlaying simulation if you know what I mean.
Finally a comment: Ricard your illustation of sonar beam is great! I would like to see the same type of image looking horizontally. Then would have a 3d idea of beam shape.
-
Thank you again EVERYBODY !
On my "to do list":
1) Drain plug from inside, or at least turned as slabbacks suggested. That's some pretty good sleuthing there slabbacks! Note to self- Do this BEFORE launching (Greg).
2) Trying a spacer block if necessary. I want to reserve that as a last option.
3) There is actually still a small threaded portion of pipe that the screen was fitted to sticking out. See if I can remove that also.
4) Get better quality pictures/video.
5) Try with the transducer out of the mount, on pole or something, away from the boat, to see what happens.
Side note. The pictures provided are with the SI at 455 kHz. When I switch to 800, the left side is not usable at all. Way to bright. Right side looks gorgeous. I'm assuming it's all related, but I'll find out eventually.
Again, I humbly appreciate all of the input and help and suggestions. I am amazed.

JL
I went through the same thing with the screen. From the help I got here I took the screen off the mount...cut the mount back to just enough threads to hold it tight and mounted a spacer and shield saver to push the xducer out a bit.
This is a shot after all was said and done with the mount along with what I started with and ended with.
Stick with it and with the help of these guys you'll be good to go soon.

First One...: Anything (or any part of the boat) that causes bubbles can be an issue...sonar does not like air...
Second One...: The unit is not pinging during Simulation...The Simulation (both the Demo Simulator and the Forced Simulator)...are a recording preinstalled into the unit memory...(I think Doug V did most of the recordings for the Simulators on a lake in Missouri or Alabama)...
If there are anomolies in the Simulator recording ...it's because those anomolies were present when the recording was made for the Simumator....
Third One...here is Rickard's beam form depiction from the rear view (right SI beam only)...

Bright images on "1 side only" could be a few possibilities...
1. *Harder bottom on that side (sonar reflects readily off of hard stuff)...
2. *Upward sloping bottom on that side (sonar reflects readily from stuff closer to 90° from the direction of the travel of the sound pulse)...
3. *Xducer rotated toward that side (aiming that side's piezo more toward the bottom)...
4. *Piezo failing on darker side (making the other brighter side seem blown out)...
If moving around over different bottom types creates differences in this "bright side"...(bright here but not over there)...then it's probably from items 1 or 2 above...
If the "bright side" stays bright over different bottom types...then it's probably from items 3 or 4 above...
I keep the SI Enhance window overlayed into my screen any time I'm using SI...this gives instance access to the SI Sensitivity setting ...which I change constantly depending on the bottom composition my boat happens to be over...to brighten or darken the SI image...
In this shot I had to nearly Max out the SI Sensitivitly to get enough of the sound pulse reflection from this mud bottom to make the image acceptable...

I would like to see the same type of image looking horizontally. Then would have a 3d idea of beam shape.
I found an older figure that I made for a discussion on the DI from SI technique. The transducer is located at the crossing between the dashed lines. The dashed lines represent left and right element surface. The shaded areas represent the distribution and intensity of sound transmitted from the left and right SI elements (starting at the crossing). Quite alot of sound is sent towards the surface. I have tried to draw a 3D figure, but these cases are so extreme that my program can't do that due to too low decimal resolution.
(There is a wide sector right under the transducer where left and right beam overlap. The large distance between left and right element array (about two inches) causes a phase shift between the beams and therefore also a complicated interference issue. The "fingers" pointing downwards indicate this interference. This is the reason why the DI from SI technique is doomed to be inferior to dedicated DI. But this is another subject and has nothing to do with Jerklips problems.)
Rickard
-
Thanks Guys. One other random thought..... the interference line appears to be farther away from the transducer than either the screen or plug. Could misalignment of or in the transducer be causing it to pick up on the port corner of the hull?
-
That’s just due to some near-filed filtering that is automatically done to the Si sonar data. Often you will see the multiple lines. Set the SI Range to its lowest setting and you may see that there are multiple lines and not just the one big blurry one.
Example:
-
Slabbbacks, your "before and after" shots are great. I can see why you were pleased with those results.
I know you were happy when you saw that come up on the screen.
Hopefully I get to do some tweaking tonight and this weekend.
-
Completely removed drain plug and the livewell screen/threaded pipe from transom. Transom was flush smooth where these were. No improvement. Here is a screen shot.[attach=1]
Transducer mounted on pole---if it was pointed out beside the boat at about a 45 (idle speed), the interference would go away!!! In other words if I just forgot about keeping the face of the transducer parallel with the bottom, and just pointed it out away from the hull.
So here is what works:
Transducer on pole away from hull and prop
Increasing idle speed from 800 to 2000 rpms
Sitting dead still for several minutes
So what the heck does that mean? Turbulance? from hull? from prop?
I'm limited to places I can move the transducer because of the trailer bunks and the chines on the hull. Slabbacks, evidently I need to try a combination like yours.
Not to hijack my own post, but I wanted to show a picture with the 800 kHz, because I think this is related to the left side interference.
[attach=2]
The two sides are way different in brightness. Adjusting to improve one side just makes the other side worse.
I can get just fantastic images from this unit while on 455 kHz even with the interference ...
[attach=3]
...but I want to get the most out of the capability of the 800 kHz transduce that I paid extra for.
For the "Connected Transducer" I have the high def sidescan selected. Is that correct?
Thanks y'all and I apologize the length of the post.
-
With the line going away while the xducer is mounted to a pole and it goes away while drifting...it seems it may be bubbles coming off the hull somehow...or the prop turbulence...
Can you temporarily mount the xducer on the opposing port side of the transom and test...?? (Maybe clamp the pole to the transom with the xducer attached and in the water..)
The darker right side in the images looks like the bottom is sloping down and away to the right...which would be normal for that side to be dark...
Do you know if this was the case...??
Keep at it...we'll get it...sometimes these things are very finicky...
Rickie
-
JL
These guys are going to ask a ton of Q. Just part of it. A lot of knowledge and the only reason my shots look like that is from their advice and tips.
-
Thanks Rickie,
The bottom is not sloping away on the dark, right side. It is all flat out there in that area.
I have enough slack available to me to try it on the port side. Going to do that now.
Thank you guys.
Curtis

The transducer is gone.
it came loose from a temporary mount.
I heard it when it hit the prop.
*sigh*
-
Dang bud! Wishing ya better luck for sure.

*sigh*
Now that does hurt...
Is your unit still under warranty...??
I would call HB and tell them the issues you were having ...and the testing that you were doing to try and trouble shoot it...(even give them the link to this thread where we were trouble shooting)...
Rickie
-
...the shock is wearing off kind of...
It's not Hbird's problem, it's mine.
Question on your rig, slabbbacks. Will that arrangement and height give you any 2d down signal when on a slow or medium plane? Or do you use a separate transducer for that?
-
I agree with Rickie. Call and speak sweetly and maybe you will get a sympathetic ear. If they don’t want to cover it under warranty ask them to please ask their Supervisor about it and reference this page on the web site. I think that there may have been something also wrong with the left Si sonar as both the 455kHz and 800kHz has a “haze” that I don’t think was due to where it was mounted.
-
Only use the stock xducer that came with the unit. I used it for both running the water looking for stuff and also jigging off the back while in max mode. Speed had a lot to do with what your going to see or not see.

Here I was running the same as above but after seeing these fish I went to neutral and was trying to find a marker to throw out
(http://i29.photobucket.com/albums/c292/tb36/cd775f5b-a7fa-414d-b6c1-c94c59f6afca_zpsc328dc1b.png) (http://s29.photobucket.com/user/tb36/media/cd775f5b-a7fa-414d-b6c1-c94c59f6afca_zpsc328dc1b.png.html)
We all get grainy images from time to time, don't be discouraged in this. We sometimes speak of snapshots worth posting and those for out on the water we use to find fish. For every shot you see from guys with nice shots posted we have a ton of not so nice shots to go with them. Don't think we have these screen views every time we hit the water.
You will find that after you get your key settings in place you will still need to fine tune it to some degree depending on depth, bottom type ect. / this is part of the learning curve we all go through.
keep at it and it will come together
-
Good grief slabbacks !!! That first image is stunning. I may use that as the background for the screen on my phone!
Thanks for the encouragement.
-
I got a new transducer, new 1" thick plastic mounting board, springback bracket and angle block.
[attach=1]

The results are about the same. Much interference on 455. But not near as much on 800.
Here is 455 pic.
[attachimg=1]
Here is an 800 shot
[attachimg=2]
Switching back and forth between 455 and 800 without changing any settings
[attachimg=3]
[attachimg=4]
[attachimg=5]
On 800, the left side still mostly looks different than the right side.
[attachimg=6]
Here are two shots in 800 of some pilings. Scanned once from left, and once from right. They look so different.
[attachimg=7][attachimg=8]
I'm grateful to be functioning again, and on 455 at least, this thing draws some amazing images. I'm still completely fascinated. But some things are still wrong. The 455 returns much better images than the 800 hands down, in almost every situation.
I lost my 2D down signal when on a plane, but I think I can adjust that back in by moving the transducer some.
Any suggestions or observations are humbly appreciated. Including any observations about how the transducer is now mounted. I have not tried this new mount with the livewell screen removed yet.
Thanks,
Curtis
-
Curtis,
Isn’t your HDSi transducer further back from the transom than the livewell screen sticks out?
Does the left Si look like this when the motor is shut down and trimmed all the way up?
-
When you are making your passes to search a area do you raise the motor some or do you leave it trimmed down?
In reference to what Greg spoke of about your motor try this. Use 455 in one test and then go to 800. Start a straight run then shut the motor off...raise the motor up out of the water and see if you still have the interference on the left screen. You may need to get speed up some to allow for the drift at your set screen speed for a short time after killing the motor. You can take a screen shot of each like you did above.
This will point to the motor as being the problem if the interference goes away. May be wrong but it's worth a check
-
I believe that my transducer is further back from the transducer than the livewell screen....not by much, but I think it does.
[attach=1]
I'm doing all the passes with the motor trimmed up, right to the point of starting into the tilt mode.
I'm not sure anymore about how it looks with the motor off, and trimmed up, so I'll check that out again. It will be a few days.
I really appreciate the help and patience.
-
Jerklip...have you been in correspondence with HB on the washed out left SI on 800kHz..??
Have they asked for screenshots of the issue...??
With the new xducer showing no improvement in the left SI at 800kHz...maybe there is something amiss in the head unit...
Rickie
-
Hey Rickie, yes I have been in touch with Hbird on the issue, have sent them pictures, and it has been passed to a specialist now. I'll see what they say. Thanks sir.
-
Rule out the motor as a possible source of the bad left Si sonar first. You can do this without the boat moving; just trim/trailer the motor all the way up. If the left Si sonar changes than you know it was the motor and if it doesn’t than it is either the unit or the transducer. You would need to find someone else with a Humminbird Si model unit (any one will do for testing) and try your unit on their power cable and Si transducer and their unit on your power cable and transducer. The testing can be done while drifting as all you are looking for is whether the left and right Si sonar look the same or not. I would go ahead and test at both 455kHz and 800kHz.
-
Hbird sent a software update for me to do. I have v6.830 and the new one is v6.860.
But I am going to do the motor out of the water testing as you guys suggested, before I do any software updates.
Do you guys know of any issues with the newer v6.860?
Thank you.
-
I have some new information if you guys are still willing to take a look.
I did the software update but I could not tell any difference.
To eliminate the motor as a source of the left side interference as you guys suggested, here are two pictures, sitting dead calm still in the water, 455kHz, and motor trimmed all the way up out of the water.
[attach=1]
[attach=2]
Here is the same thing, sitting dead calm still, motor trimmed all the way up out of the water, but this time on 800kHz.
[attach=3]
So there is still some interference, even with the motor up.
I have not found anyone yet to try swapping out with to test, but I'm looking.
And please look at that 800 image above. The left and right side still do not match, and you can see strange layers coming up from the bottom on the left side scan, and DI.
Thank you again for any advice.
Curtis
-
Did you send the original CSI xducer back to HB as a trade in..??..(another xducer to cross test with would be beneficial)...
Also...stay in contact with HB while the unit is still in warranty...(did you register for the HB Select Program...??)...
I think something is amiss in the head unit...
Rickie
-
Yes sir, I did send the original CSI transducer back for the upgrade.
But this is my second XHS 9 HDSI 180 T transducer. Same results for both. And I never tried the original CSI model.
I will stay in touch with HB. I did register the unit, but I don't know anything about a "Select" program. I'll check that out.
Thanks a ton Rickie.
Curtis
-
I got a new transducer, new 1" thick plastic mounting board, springback bracket and angle block.
(Attachment Link)
Jerklip
This may be a long shot and maybe some of the others could tell better...in the last picture (in the post in reference to you mounting the 1" mounting block) it looks as though the transducer has a angle to it. It looks like the left side is tipped up more than the right based off how the boat is setting.
-
Thanks Slabbacks. I've moved the transducer (several times) since that picture.
This is what it looks like now. I tried to get it square with the world, and if anything, it may be tilted up on the right now.
[attach=1]
[attach=2]
Not sure if you can tell anything from these shots or not.
Thank you,
Curtis
-
Big difference in that shot. I hope you can get her figured out with all the work your putting into it.
So the last shot I just saw is the set up you done your last test with?
-
Yes sir that's the same set up I did the last tests on with one exception. The back end (trailing edge) edge of the transducer was angled down more. I raised it some just to take these pictures. I can still get a 2D bottom signal on a pretty fast plane with it tilted down a few degrees so I like that part.
Thanks sir,
Curtis

Here is the HB Select program that will give you a second year warranty...
You should sign up for this before your 1st year goes out...(and the sooner-the better)..

Couple of questions
1. Do you have the 'ducer cable routed to the helm near any power lines. I would expect it to affect both left and right readings but you never know.
If it runs near any powerline you want to have them as perpindicular as possible where the two cables meet to eliminate crosstalk.
2. Do you have the bilge pump/aerator or any other pump going while testing? It looks like you have an intake, and two outlets just to the left of the transducer?
3. Are there any other electronics turned on while this is running, have you tried it with the motor trimmed all the way up and everything else in the boat completely turned off?
If you still have the problem after testing it with everything else turned off/motor up...I'd start to suspect the head unit.

Got that RIGHT! :)
http://www.humminbirdselect.com/ (http://www.humminbirdselect.com/)

If those last three screen snapshots were taken with everything on the boat turned off I would try mounting the transducer on a pole long enough so you can stick the transducer down below the level of the boat and then rotate it around to it points in different directions. That will point to or eliminate anything on the boat blocking or reflecting the left Si sonar. It could still mean a bad second transducer or unit though, so if you cannot find another to cross-test with; send both unit and transducer to Humminbird to test and possibly boat test if needed.
-
Rickie, I registered with Humminbird Select today. Thanks for that.
Spyder - I'm sure the ducer cable is routed near at least some power line(s) as it runs from the head, down through the console, and down the length of the boat to the transom. All of this routing is through enclosed areas and I'm not sure I can do much about the proximity to power lines in that situation.
But yes, I tested with everything in the boat turned off. No aerator, no bilge, no front sonar, no nothing. Dead calm still after several minutes of drifting, and the motor trimmed up completely out of the water. Everything quiet as a church mouse.
Thanks for helping yet again Greg. I will test again on a pole as you have described.
-
Tested with the transducer on a cane pole.
The interference will go away, but only after lowering the ducer 5.5-6 ft. down into the water !!
3 ft down, still interference.
4 ft down, still interference.
5 ft down, still interference.
My hull only sits about 18 inches down into the water.
But around 5.5 - 6 ft down, the interference line merges into the bottom signal, and goes away. Actually the bottom signal comes up and kind of absorbs the interference line.
This was tested sitting dead calm still in the water after several minutes, with the motor completely out of the water, and nothing on except the transom/anchor light (night time). tested at the transom.
This shot (455) shows no interference - Fantastic !! But the ducer was about 6 ft. down. Note the depth only shows 3.6 ft but I was in about 10ft. of water.
[attach=1]
This shot (800) show no interference again - Fantastic again !! But it was nearly 6 ft. down again.
[attach=2]
The disparity between the left side and right side on 800 is mostly gone in this image. And the strange color layers just above the bottom are gone....unlike in this picture from earlier.
[attach=3]
This shot is with the ducer 3 ft. down below the surface, in about 10 ft. of water. Interference is back.
[attach=4]
I missed the best pictures of slowly raising and lowering the ducer back and forth from 3 ft deep to 6 feet deep, and seeing the interference line come and disappear back into the bottom signal. But I do have this one that shows the effect a little bit.
[attach=5]
I did rotate the transducer 90, 180 and 270 degrees while testing on the pole. No real changes as I rotated. If I only had it 4 ft down, there WAS an interference line and rotating did not change the look. If it was 6 ft. down, there was NO interference, and rotating had no effect on that either.
So....I'm plenty frustrated. I can't very well operate it with the transducer 6 ft. down into the water.
I have NOT run a dedicated power wire directly to the battery yet. It is still wired to a lug under the console.
I will follow up with Hbird CRC as well with this information.
If you don't mind, I would appreciate any further observations and suggestions.
Thank you,
Curtis
-
Well at least you eliminated the boat as a possible cause. It’s down to the (new) transducer and/or the unit. I think that you are just going to have to ship them in to Humminbird to get them tested. I would ask if they can be tested together on a boat if there is no problem found while bench testing.

And send HB a copy of your diagnosis trials that you listed above...with pix

Seems to me that jerklip has gone the extra mile in all his testing efforts and HUmminbird should stop messing him around and ship him a new unit, new (free) transducer, and apologies, he can send the bad unit back for all their testing. Not impressed with this kind of customer service!!
-
At any time jerklip, or anyone else, could pack up their unit and transducer and shipped them into the Service Department for testing. However, without first taking the time to troubleshoot where the problem is he could have well been wasting his time and money. Usually these sort of issues are from a physical blockage of the Si sonar beam and not the unit or transducer. If blockage were the root cause of his problem we would be well on the way on how to overcome this with a different placement of the transducer or some other option.
When I worked as a Service Tech the number one diagnosis was that there was no problem found with the unit or whatever was shipped in. If at all possible I try to prevent units being shipped in when the unit is not the problem. I’m sorry that you disagree.
-
Hbird customer service has already issued a return authorization number (maybe not the right language) and directed me to send the unit and transducer in for evaluation. So they are engaged and moving to solve the problem. I'm thankful for that.

Sending my 1199 back for the same problem.I tried my 998 on the new transducer and it worked great. Think this bug is in the head unit of the 99 series.
-
I don’t think so gbishop. If it were you would be seeing a whole lot of Internet chatter about it.
I already got an e-mail and phone call about your unit from the CRC folks jerklip.
-
Greg it may not be in all of the 99 series units but I put my 998 on the new transducer and it worked great like it always does.the interference in my unit is worse than jerklips.My unit will be shipped in tomorrow.
-
Hopefully the Techs can pinpoint the problem and get it right back out to you gbishop.

Sent my 899 and HDSI ducer in to Hbird service on Friday, and they had it back in my hands Thursday. I thought that was pretty good.
The interference line is diminished, but not gone. But I can live with it.
But the big difference between the left and right side on 800 is still no better at all. The left side still looks like it's over heated or something in the pictures. Plus it still shows the layers coming up off the bottom on the left side, and DI. NEVER do these layers show up on the right side.
I'll be sending these pics to my CRC rep again tomorrow.
Some of these pics are with the motor up, off and drifting. Some are idling...you can see the prop wash. All except the last are on 800.
The layers disappear and reappear as the bottom depth/signal rises and falls.
The last picture is just showing that the interference line is still there on 455. This is motor up, and drifting.
Lastly, I posted some interesting screen shots in the "general pictures and screen captures" area of the forum, of some object I found and just looking for opinions as to what it may be.
Thanks all,
Curtis

It was my understanding all 2014 SI units have an 800KHz "wash out" software issue that they are working on...
I have a new HDSI XDCR, but have not installed it because of this - Greg??
Any words of wisdom here????
-
None Robert.
That is my understanding as well.
-
Well... in due time!
Let's hope that NEW young gun you guys got is a whiz bang programmer!
-
Hi, am having the same issue , did you sort it out?
Thanks
-
I pretty much have the same problem on my 899 unit. see bright line thread
-
Just to maybe bring this thread to a close, I sent my unit in for repair again and apparently this time it works. I had been away from the forum for a while and when I came back I read about a new fix that involved software AND hardware. So I dug up my old emails etc., requested a repair, and BINGO....it works correctly now. I have only tested it one time for a short period, but it sure looks like it is finally fixed. Nice looking images on both sides with 800 now. I will try to come back and post a few images. Thanks to all of the fine forum members who helped so much. You know who you are.
