So, my LG plasma went out and with a little google "research" come to find that the problem I am having is related to the power board. Apparently you can either replace the board for around $200 or so, but from what I understand you can also try replacing some of the capacitors that look like they are bad. When I took the cover off the back of the TV, I can definitely see about 8 or so that are bad. I imagine capacitors are pretty cheap, so I am looking for a supply house that I might be able to find some of these capacitors in the Milwaukee area. They are far bigger than something you would find at Radio Shack. I did some google searching, but anyone have a recommendation in the area where they buy parts like that from with decent prices/helpful staff?
TIA |

This, but don't do it. Power supply caps go bad because the components are defective, they weren't properly derated for the application, the PS has a short on its output, etc. Putting the same ones back in is asking for the same problem; unless it was just a bad run of caps with a manufacturing defect. If the problem is so well known that you were able to find fix-it info online, then LG may offer some sort of support deal. Best to let them fix it. What you really want is for them to put in a new unit that is a revision later and fixes the problem. Coaxing it back into working, or buying the exact same replacement PS from the manufacturer, is a mistake. Something is wrong. If you're killing caps you're also risking fire. $200 repair? What does a TV cost these days, $300? If they don't offer to have it repaired at their cost, then press them for a $200 rebate towards a new TV, but don't leave a questionable appliance plugged in at your house. You're lucky it gave you warning. Heed that warning. |

From what I hear, if you buy quality ones from a supplier and put them in, the problem usually goes away and won't happen again. I'm finding out that not only does LG make shitty TV's, but they also have the same level of customer service. Plus the TV is five years old and I doubt they are going to replace/repair anything under warranty. My buddy bought a LG last x-mas and it went bad in two months, well, six months later he finally got it fixed by LG, no thanks to that kind of run around. The $200 is to by the entire power board online and replace it myself. I don't know where you're going to find a decent 50" plasma for anywhere near $300, but I really don't want to buy a new TV anywayl. I try not too watch a lot, because it's mostly crap other than football and a few other things, but I still don't want to junk a TV I paid a lot for five years ago. |

Quoted: Try here. http://www.badcaps.net/ His name is Chris, he owns the joint. He is a family member that lives in MO, and deals with this sort of thing all the time. He either has the caps or can get you the caps you need. Let him know Todd sent you. Small world. I was going to recommend. Purchased kits for some particular PCs that had "known issues" similar –– worked well. Cool. |

Yup, they are probably the same era of caps that went south on motherboards... huge in the PC enthusiast market... big problems, it's probably the caps are they bulging? |

Yes they are bulging and some are even beginning to leak slightly. Thanks for all the help everyone. I'll let you all know if it works or not! |
