I came home from work yesterday turned on my set and it showed up with half of the screen no signal snow from cable input (default start input) and half the screen with lines vertical I think this is t-con problem has anyone seen a pattern like this and do you agree or disagree that the repair path should start with t-con or with main board this set also has led address board if this is relevant I am inserting two pics first is prestart image then second is where it stays after start can someone share their opinion thanks Guys any advice would be greatly appreciated
