Lowrance X85 Display Error

[VTX1800Shanty]

My father purchased a boat with an X85 on it. It worked great for a few years but this spring it has a problem. I checked the wires and all connections/pins appear to be good. When I turn it on, the screen does display a line running through the center. When I toggle through the menus it, I can see the display changing/flickering but it looks nothing like it should. I tried a soft reset and a hard reset (see below) but that did not fix the display. I connected a different transducer and got the same display. I am willing to pull out the allen wrench and open up the back, but I don't know what to look for.

*Soft Reset - Restart the unit after a freeze (a 'soft' reset) by turning the X85 to "Off". Then press the "exit" key and, while keeping it depressed, press and hold the "pwr" key. When the unit powers on, you may release both buttons.

*Hard Reset - Delete all stored data ('hard' reset) by turning the X85 to "off". Press both the "left" and "right" arrow keys, and, while holding both down, press and hold down the "pwr" key. When the unit powers on, you may release all buttons.

The first thing to do is to make sure you've got 12 volts going to the unit ... they do funny things with low voltage.

Yep - The boat fired right up and X85 is hooked up to the same battery. I even took a file and cleaned up the connections going to the X85.

I'd still test the voltage to be sure .... just because your motor fired right up and just because you have clean terminals doesn't guarantee that you're getting 12 volts.

You should test the voltage at the connection to X-85 .... even if the battery is good, a problem with wiring or the fuse holder could cause a voltage drop.

Low voltage is a common cause of problems with electronics and testing it is a quick, easy thing to rule out as you try to track down and solve the problem.

Good luck getting it figured out.
