Try disconnecting the cable to the T-CON board, but at this point it does sound like the main board problem because it is not sending the command signals to the power supply board.Never stop learning

Re: Sony KDL46S5100 Screen or Main Board?
I have a KDL46S5100 with a slightly different issue, double images, mostly on the left side of the screen. I thought right off the bat, T-CON but I was wrong, would a main create this problem or is it a bad screen? It plays TV, it is just all double images.Comment

That sounds more like bad tab bonding.

Re: Sony KDL46S5100 Screen or Main Board?
After looking at your links I totally agree, I removed the aluminum frame and put pressure on all the tabs but couldn't change the look of the picture, I would love to fix it but I don't know how and I didn't want to tweak the screen for fear of breaking it so any suggestions? Is this an easy fix or should I just part it out and move on?Comment
