Plasma TV-power light does not come on

The fuses are inside the TV is you remove the back cover but even changing the fuse it might not work because it could have other failures in the other board assemblies.
How old is your plasma?

have you tried a completely different wall socket altogther/

You have a power malfunction. Recheck your power connections. If the TV still persists in behaving in this manner don't try to turn it back on, but do find out if the TV is worth repairing. Most now are made so cheaply that nobody will try to repair them. I've always bought used televisions, even when they had vacuum tubes. I bought my LED at a major store's resale outlet and saved a bundle. (Quite frankly, TVs and other electronics today are so complicated and untized and made so cheaply- and sold so dearly- that if one goes bad you don't even bring it in except for them to verify it. Then they give you a new one. They're simply not worth repairing to the companies. and its an opportunity for them to sell you a better one at a discount. Of course, if you are under warranty, you might be all set. PS: those extended warranty contracts are not worth the paper they are printed on and no smart consumer ever buys one. they're for suckers) Good luck.

Switch off TV, switch off power, remove plug and wait for 48 hours and retry.
If problem persists, I suggest it is better to refer it to a qualified service
technician, since the back cover has to be opened for investigation/rectification.

Hello,

Your power supply board is dead, u know basic electronics’ and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.
hope this helps...

The problem with the set is bulged electrolytic capacitors in the power supply.

your power supply board is going out.

The only solution at this point would be to get the power supply repair since new boards are not longer being manufactured. In about 95% of the time if the LCD doesn't power up or turns OFF by itself or need to be unplug for some time to make work again; those are the symptoms of a dying or defective power supply.
I service these power supplies, for more info write to [email protected]

Describe the past - How did it fail? One day or acting up for a while? Could be a weak power supply - a bad capacitor on a power supply too. Look for popped up capacitor top inside.
