Mine does the same thing , too. I turn it on and off repeatedly , but nothing happens.I unplug it to see if it resets and nothing still .
SOURCE: tv turns itself off after bout ten seconds
Your over voltage circuits(hi-voltage and low voltage) are defective.When the voltage exceeds the specs it shuts off the tv.Unless your a service tech,you can't fix this.There are components on the main circuit tha t have to be changed.Sorry, no easy fix.

IT SOUNDS LIKE YOU HAVE A POWER SUPPLY PROBLEM OR RELAY PROBLEM. BEING A 20 INCH SET IT IS NOT WORTH REPIRING. PARTS AND LABOR WILL BE OVER $100.

I'm not sure what TV model you have. But, thing I can tell you is the most common problem.
Most of the time with flat panel TVs, the power supply for the screen fails. And the TV normally turns itself off to protect other parts in the TV from being damaged. Basically " Protection Mode".
You can try leaving the TV unplugged for 30 minutes so the TV can reset itself; then try again turning it on. If it doesn't work after that, it's time for the TV repair shop.

If you leave the tv unplugged for 2 days (atleast) then plug it back in and try to turn it on and if it comes on its the power supply board. If it comes back on it will probably shut off between 30min to 4hrs and you would have to unplug it for 2 days again. All the power needs to drain out of the tv. If thats the case take the back pannel off and check the part number out on the internet. Not hard to do becarefull touching things the power supply does store a little bit or shock in it. Good Luck.
Testimonial: "while we did not unplug the set, we let it sit for 2 days and we were able to turn it on by the remote & manually....does that still sound like P/S"
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 on the PSB. Many major electronics companies Philips/Magnavox,
Sony, Panasonic, and others 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 $$$$$$$??????? (Is it
under warranty?)
2. Open your TV and find PSB. (The board that the power cord
plugs into) Check for faulty caps. If you find some (bulged or leaking) bad caps
replace the entire board. The entire
board costs around $250 right now because they are in high demand right now. They
can be found at tv-part.com but supplies are limited. I would definitely shop around though.
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. I'm working on uploading pictures to help
guide people though the process as well.
Let me know if I can do anything to help.
Hope this helps and Good luck.
