I have a samsung HP-R4252 that has sound but no picture (screen does not display anything). I turned the unit on, and something on the top part of the upper Y buffer board blew (with pink smoke and all). I ordered a new upper buffer, which when installed, sparked in the same exact place. What could be causing the two boards to go up in smoke? I checked all fuses and diodes as per the repair manual on the Y-board and they check out ok for continuity.
