I bought a new Humminbird Onix 8 touch screen a couple months ago. I've had it out on the water at least 6 times and it had worked great until yesterday. I powered it up and could barely see the screen display. I can only barely see it if the sun is shining directly on the display. I checked voltage with it off and with it on at the factory power cord. 12.68 both on and off. It is wired with 8 gauge power and ground wire back to starting battery. The brightness is turned all the way up. I brought it back home and powered it up with an external power supply and a different power cord I bought so I could play with it at home. It had the same problem. Does anyone have any ideas on this? I will call Humminbird tomorrow but I just wanted to make shure I wasn't overlooking anything first. I have examined the pins on the unit and they all appear to be straight.
