Vizio P42HDTV10A 50" Plasma
When i first turned on the unit, there was a vertical black bar with a single green line in it. Upon further investigation there is water damage to the lower XR buffer board and the board is missing pins, most likely causing the vertical black bars. Loud buzzing coming from ZSUS as well.
Ordered a new XR board and it arrived with some bent pins, but i threw it in anyway to see if the black bar would go away since the bent pins were not in the area of the original issue. The ZSUS no longer buzzes with the replacement board in. Its looking like the panel is done since the original bars are still there.
(Left bar is from water damage. Middle discolored bar is from bad pin on replacement board)
(Model sticker and back panel overview)
(Control board)
(ZSUS)
(XR Lower buffer board)
(Water damage, blown/missing pin on XR Lower buffer board)
(Ribbons that were affected by burnt buffer board slots)
(Example of a clean ribbon for comparison)
