Last Friday my screen turned green you could still see the bottom and fish but everything had a green overlay. Well I reset to defaults and it came out of it. On the next trip yesterday it worked fine all day I had turned it on and off a few time then all of a sudden it did it again this time the screen was blue but not like b/4 just the water column was blue so I tried to change the screen color and the sounder wouldn't go back to it,s original color even though it was an option. Both times the 898 did this I found a little piece of weed on the transducer bracket. Could that piece of weed make the processor heat on the mb which in turn would cause a corruption of the firmware? It would seem time is ticking on this unit which is always garaged and left connected. It's wired straight to a new battery with a spade fuse in line. I,m thinking switching the firmware then switching the firmware back to 6.4 because that firmware seems to give me a better picture. Opinions? Ideas?
Thanks in advance Gat
