Well the top quarter of the screen works (as well as bottom) but past that it is cut off. (The whole screen is primed though)
Normally I would think a buffer failure but when there is a bigger signal (lets say snow for cable) then the whole screen will show as well as the hidding menu.
I can sometimes get the rest of the menu to show but it flickers (but only flickers under that quarter of the screen that is fine).
So I have narrowed it down to a drive board failure. The power supply checks out. I do not know what the other check points on the SC board are so couldn't really verify but if you wanted to know I could get those for you.
I want to cancel out the SS board since that top portion is fine and it's symptoms seem opposite of an X/Z failure on a plasma.
This happens on all inputs so it seems D and A (integrated) would be ruled out and since it seems to processing correctly.
I think it is in the buffers or SC board but not sure, never seen this.
