I have a Sharp Aquos LC-C4654U I bought at Costco 22 months ago (still under the 2 year Costco extended warranty). It has thick vertical color bands that happens on all inputs and even with inputs unpluged. Also, when you press the menu button, volumn, or change channels, you don't see the on screen display. Basically the color bands are permenently on, all the time, no matter what I do. The sound works fine. Just the video has a problem. I tried unplugging, holding power for one minute, and plugged back in, to try and reset. Also, I plugged it into a different outlet. No luck. I called Costco and a technician is coming over next week to attempt repair.
Anybody seen anything like this? I searched the forums and don't see anything like this. There are a bunch of threads on the obvious "Sharp banding" problem. But the problem I'm having seems to be entirely different.
