Re: LG 60PZ550 Plasma - No Sound, No Picture
Swapped the Z-sus board and still no change in the TV behavior. Checking the vzb test points on this one and all I see is a rise to ~0.2vdc then a slow bleed off. The original gave me a rise to 6vdc then slow drain down. Any thoughts?
I obviously cannot 100% rule out this 'new' board is also bad. It was described as 'working, pulled from a TV with a cracked panel'. If we suppose that this one (or my original) is possibly 'good', are there any other causes for the vzb voltage loss? I am not opposed to ordering another Z-sus board from a different supplier, if we feel confident that the problem is limited to that board.
