Problem details
We are w/out any picture, only a black screen. Audio still works fine. The TV is only 15 mos. old. Happened while in the middle of watching a show, and never have had any problems prior. Not even the menu is visible.
Best solution
you need to replace the Y-main board the buffers are just that, the Y-main drives the upper and lower buffers, this Tv has a problem with the Ymain going out and trying to draw to much current from the power board causing the burning smell
