I'm new to the forum and have spent the better part of 3 days trying to learn what I can about plasma TV troubleshooting and repair. I just picked up a Vizio VP50 HDTV20A 50" plasma for 50 bucks hoping I'd learn something repairing it but I opened her up yesterday and I'm starting to think I bit off more than I can chew. It's a Samsung Panel S50HW-YD02 and I've tried cycling though inputs with the Y-MAIN and X-MAIN disconnected (in turn and both together) but I'm not getting any sound. I looked at the Y-MAIN board and found a badly burned capacitor C5601 and 2 burned resistors right by the connection for the buffers. The capacitor is unreadable so hoping someone can tell me the value so I can order a replacement. I tested the buffers following a tutorial on the Coppell repair blog and concluded that they are both shorted. I've also found a swollen cap C5709 on the Y-MAIN right by the power input connector. Surprisingly there were no open fuses found on either the X or Y board.
On the other side of the board there are other issues. A 680uF capacitor right by the power input connector on the X-MAIN is burned. At the very least I'll be replacing a few components on the X and Y boards and hoping I have sound from the set after that and if I do I'll deal with the buffers. I am very much a noob at this and hoping I'll get some help along the way. I'm doing this more for the learning experience than anything else so I'm willing to stick with it as long as it takes. Has anyone worked on this set before? In your experience is there likely to be other damage besides what I've already seen and please post value of the toasted capacitor if you happen to know. Thanks. Great forum, hope to learn a lot here.
