I am looking for someone to repair a bunch of power supply circuit boards and was wondering if anyone here knew of a good place/person that would be able to repair them. I have a bunch of LG TV's and the power supply boards keep going bad. I had one where someone used a device to heat the whole board and remelt the solder and it worked fine, so I'm assuming that's all that needs to be done to these.

Thanks.

I didn't know anyone still repaired them. I remember the days when you pulled the vacuum tubes out and went to the local Safeway grocery store. They actuall had a tube tester and stocked replacements. That probablt dates me a little.

I put new capacitors on my power supply board for my Samsung TV and it brought it back. For the issue I was having, TV would continually try to turn on and fail, there were a lot of youtube videos on how to fix it. They even sold the capacitor kits for the repair for < $10 on Amazon. Might want to do a search.

On these, the TV turns on and works fine, then shuts off after some time. Could be 5 seconds, a minute or even an hour, but it will get worse.

For a project like you describe ... I would say that a temperature controllable lab grade grounded soldering station with a variety of tips could be helpful.
