Hi guys, got this set in today and the picture is black & white with a sort of tartan hatching all over the screen.
Not opened it up yet but from what i can gather most of the internals should be made by LG.
Never worked on a plasma before so will be asking a few more questions as this thread goes on.
From what i've read so far the main culprit could be the z-sus board but please put me right if i'm on the wrong track.

All advice gratefully received, cheers Dale.
