![]() When a plasma panel is shattered while running it shorts internally and sometimes kill the buffers, y-sus and/or z-sus, also if it is powered on while the screen is broken.
That said, always test the buffers before powering on the TV, in your case the Y-SUS or logic board may be bad. There's this thread which the Y-SUS made an effect that is very similar to buffer failure, I had no idea and recommended a logic board swap to the user. https://www.badcaps.net/forum/showthread.php?t=97716 |

![]() pretty sure its pins 1 and 2 on these sets also think you have to dissconnect the cable between the main and control board maybe wait for another member to confirm its the rite procedure

![]() That's it, shorting the AUTO_GEN pads on the logic board with the LVDS cable disconnected, the TV will start on with a black screen the jump between colors and patterns each 2 seconds or so.

![]() Doesn't look like it, the horizontal lines are the cables not properly inserted or the buffer boards being damaged, the bad image is from the Y-SUS, something is damaged.
There's a single vertical line in one of the pictures, that could be not reversible, or just part of the pattern since it does not appear in the other photos. |
