i installed a ken wood touch screen deck in my jeep 2 years ago and it randomly cut out on me 2 weeks ago and went black. I took the screen out checked all wiring and fuses and there seemed to be no visible problems so I put it back together, and started the car and it worked. About 2 days ago it did the same thing. Today I took it out again and checked everything again no visible problems. It is connected to the cigarette lighter to power it when the cars on and that is still working no problem. I'm stumped any help would be greatly appreciated!
