I recently picked up a used Insignia NS-P502Q-10A 50" plasma TV that would not power on from a friend. "Please see if you can fix it for cheap" (We've all heard that)
It had a badly arcing y-sus board (would crack and spark like a stun gun!) so I threw in a replacement, checked all connections and grounds and it fired right up. The picture is excellent and all functions work, except for one thing! There's a single line of sparkling pixels on the left edge of the screen. (See pic for an example it looks like more, but it is only one line) In the bad old days I would have thought it was some type of overscan adjustment on a tube-type tv. But I just don't have enough experience to know where to start here. I didn't do any adjustments on the YRR or VSCAN pots on the replacement board, but my limited knowledge didn't lead me to believe this would make a difference as the black levels are good. For reference, the board I replaced was a Samsung LJ41-06153A.
Any help would be appreciated! Thanks.
