Deh-6400

[MTXman 10+ year member]

I have a Pioneer DEH-6400 head unit, and since I got my subs installed - about 3 months ago, the screen's lights, reverse the colors pretty often and is especially annoying at night. What I mean, is that the blue changes to white, and the black changes to white. The colors just switch, you can still see everything, it's just the opposite color that it should be. It probably does like twice a minute for about 20 seconds. This stops if you touch any button.

It may just be a loose wire to the deck, but maybe it's an option that I can change?

Has this happened to anyone else? Anyone else with this head unit?

Thanks for your help in advance.

Thanks alot man! I don't know if that worked, but I am guessing.. a beep sound is always good.
