Hi all,
I was experiencing a thin black line (horizontal, full width of the screen) and red sparkles on the screen (more noticeable on a white background or test pattern than normal tv).
I ordered a new Y-buffer figuring since it was just this minor issue, I wouldn't need to replace Y-sustain (or Y-Main as Samsung calls it).
I installed the new buffer board, the screen flickered red a few times, then "pop" and now both the y-buffer and y-sus have dead shorts to ground!
What could have caused this reaction ? I was very careful about part numbers, everything matched 100%!
I was trying to avoid replacing the Y-sus, since it cost me nearly $120 for the buffer alone - the Y-sustain would have doubled that cost!
How do I find what went wrong with the Y-sustain ? I can swap out transistors, regulators, etc if I know where to look.. I think the buffer is a lost cause.. there are 12 ICs and almost every one has multiple shorts to ground.. I don't have a hot air station to replace these anyway...
Thanks in advance..
