Your power supply is shorted; remove it from the set and, have a TV shop repair it if you are unable to do the repair yourself.
any good shop can do the repair easily and, much cheaper than the manufacturer you can find the power supply by looking to where the power cord enters a circuitboard that will be the power supply

I have a 1 1/2 year old Panasonic TC-P42U1 plasma tv. While watching a show, it suddenly shut off and won't come back on. What do you think caused this and how can i fix it? Thanks.


Try unplugging it completely for 30 seconds to 1 minute. Plug it back in. If it still won't come on, it's likely taken a power surge and popped a fuse or power supply, which means a trip to the service center.

My pioneer plasma TV shuts off by it's self only after a few seconds?


From what it sounds like here is your power supply unit may have some issues.

1. Take it to a repair shop if your not good at repairing this.
=======================================
If you are a tech:

1. check relay for clicks
2. check eletrolytic capacitors for buldging or holes.
3. Fets for voltages (req service manual or scematic)
4. Replace power supply.

Thanks I am sorry this was basic information but it was free and I would like if you please leave ratings and feedback on your free answer today/

Power shuts off


Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
But, I can't say it's 100% the problem because I can't actually look at the tv over the internet.

If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20. And most cases the new part cost less than $15.

I hope I shed some light on the subject for you.

If the repair shop says it is powerboard it means they already took a look at the TV and you dont need to worry about it.
If you have any doubt please post the sympton here (detailed) and I can tell you for sure what the TV needs.
I need to know what the led does and how it does.
