    I'm looking at this TV for a friend of mine. It's a Sharp LCD 42" TV LC-42SB45U and on about a third of the screen the colors take forever to fade. They just layer on top of each other.

    To make a long story short, I took off the back cover, powered on the TV and was able to correct the issue temporarily by gently twisting the screen. By that I mean pushing the top left corner of the TV back and pulling the top right corner forward.

    This makes me think that there's a bad connection where the display board goes into the LCD panel itself. My question is, are there any repairable parts there, or does it just need a new LCD panel?

    You might affect a permanent fix by fitting some form of 'pressure pad' along the edge where the connections are made by trapping some foam rubber (or whatever) between the screen and casing but those connections are generally not fixable.
