Default Samsung 204BW LCD Power Board Problem

Upon further inspection, there appear to be some electrolytics bulging
on the power supply board (C111, C112, C114). *Resistor R113 appears
to have sustained damage as well, but I cannot tell its value for
certain. *The board itself is model IP-43130A. *I'm curious if there
are any common failure modes for this board.

If anyone has a schematic/service documents or other troubleshooting
suggestions they would be greatly appreciated.

Thanks!


I have the same board in my Samsung LCD. I think I have dirty power
at my new house which blew it. One of my capacitors seemed to blow
too (C316). There is also a high pitch whine that is comming out if
it which is usually caused by a blown transformer. I'm currently
seeking a solution for it whether it is buying a new board or trying
to fix the one I have. If you get any leads, please let me know and
I'll do the same. Thanks!
