One thing to try first is a good cleaning b4 replacement , power supplys go bad lots of times due to overheating ,dust tends to stick to them and over time it acts like a blanket holdin heat in , cans of "dust off are way cheaper than pwr supplys too

Is there anything I can do to fix the power supply if its failing on my LG Plasma 60in

Replacing the poser regulator board to a plasma tv [of any brand] is a very skilled work. After replacement, some critical adjustments should be done, and is a skilled work. Contact any experienced service technician or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience.

Tv turns off itself

When it have this kind of error is a problem of the power-board.
Anyway you must open it and look at the all capacitors and if are them inflated, if them are inflated must change them.

Good luck!

My 2 year old 60in LG plasma turns on and then turns off right away automatically.

I had a similar problem with my 42 in Philips LCD HDTV.

Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors. Many electronics companies were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems.

Here are some options for you.

1. Have it fixed by a professional

2. Open your TV and find PSB. Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board.

3. Remove and then replace individual faulty caps. This takes some soldering skill.

Caps are inexpensive and if you can take care of it yourself it will save you hundreds.

I have a tip/tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. It's called: Fixing the Philips Turns/shuts off on its own problem.

Hope this helps and Good luck.

I have 50" lg Plasma tv. When I start it first thing during the day the power comes on then shuts off. I have to repeat three or four times befor it comes on. I have checked the power source and the cord...

The UF capacitors on your PSB-power supply board are blown. Your tv is putting itself in fault protection mode to keep it from damaging more components internally. Soon enough the TV won't come on at and you'll be left with a blinking fault LED.

50" lg plasma tv keeps shutting off

Your Television uses a sensing circuit that is basically part of a mini-computer. Sometimes either the sensing unit can be bad itself or there is a power distribution issue.

Test - Make sure you try another input source like DVD or something other than what you are trying now. If it plays and does not shut off, the TV might be ok, it might be something to do with your other source you were using when it went out, like your cable box etc.
(most LG's have input sensing and if there is nothing coming in the TV it will shut down or go into standby)

If you have run this test my friend, you may have no choice but to take it in or have a service call. A LG specialist might bring the board you need in to repair it but that can be rare. Most of the service guys that come out are following instructions in a systematic troubleshooting guide and do not really know how to troubleshoot per say, they are card replacers until it works.

They cannot fix the problem in the home if you cannot repeat the problem in front of them and it is consistent.
You may want to call LG or Write their tech dept (good luck, they kind of are not that customer service oriented that I have seen).

I always recommend the extended warranty on a high-ticket item next time.

Hope that hepls and let me know how it goes.
