Description: 50 Inch 720p Plasma
Condition: Distorted picture

I have heard that my buffer boards were to blame for the problem I am having with this TV. I have posted some pictures of another TV that is doing the exact same thing.

1. Just to confirm does this appear to be a buffer board issue?
2. Can I buy just the upper buffer board to test it out and if I do so if my bottom buffer board is broken will that damage the top one? My y-sus connects to the upper board and the top board communicates to the bottom buffer board.

This is NOT, I repeat NOT a upper or lower buffer problem.

The upper and lower buffers are for Horiqontal sweep, not vertical sweep.
(The lines would run left to right if a buffer problem)

High probability of a bad controller or panel.

Hope this helps.
