My tv went out in an instant: one second a picture, and then next only sound and a black screen on the left and right portions of the screen, and vertical lines in the middle. A little investigation on the internets showed that the problem is often the t-con board. I sent for one, replaced it, but the tv is doing exactly the same thing. Any suggestions?



Thanks,

Thanks, Tony. What's the fix? Should I replace the main board to see what happens?

Hi,
It could be a hporiz. driver for the panel. Some has hidden diagnostic
mode(service mode)
