Default Re: Sony Bravia no picture but backlight on

Hi. Can anybody explain the difference between signal board and main board?

I have this tv KDL46xbr2 white short (1/2 inch) horizontal white lines that appear and disapear on the whole screen. It does it on all input but it does not affect OSD (menu).

Deciding if this problem is on the signal board or main board.

I will appreciate any suggestion.
