Hello. Most likely you have a blown fuse. Take your flat screen into a tv repair shop to save yourself a huge house call fee. J.

That would likely be a power board failure. If there is no power inverter in this model, which I don't believe there is.

    The power board is the one that has the plug-in attached to it. There should be a fuse on this board as well.

    The power board is the board that is attached to the plug-in cord for power. There may also be a fuse attached on this board. It would be a glass bus fuse. It will have a printed number on the metal end of the fuse.

Sound like the TV is in protection mode. This happens when a part goes bad inside. the TV turns OFF to protect the other parts from being damaged.
Most commonly it's a power supply related issue. A bad capacitor or transformer on the power supply board is to blame.
For a do-it-yourself fixer with electronic experience, a Service Manual is the best for trouble shooting the problem down to the bad part. Normally, you can find it over the internet for less than $20.

Sounds like there is a problem with the power supply. Try unplugging the T.V. and hold the power button for 30 seconds. Plug the T.V. back in and see if that helps. If it doesn't try switching to another outlet, and if that doesn't work then you may need to replace the power supply which would probably cost anywhere from 140 to 200 for one.

There's a good chance you have failing electrolytic capacitors either in the power section or the inverter section or both.
Any caps in these sections that look bulged at the top, or bulged/leaking at the bottom (look for discoloration of the circuit board around the base of the capacitor) need to be replaced.
If you repeatedly turn it off and on, eventually it'll probably stay on, but every time you turn it off, the unit will get harder and harder to start up until one day it just won't.
Sometimes you have to do the opposite to start it up and unplug it for some time and then try again.

If you aren't tech savvy, don't worry, read the rest of this solution and watch the videos.

If you are handy with a soldering iron and can identify the power supply and/or inverter / FM section for the backlights, an inexpensive handful of capacitors will likely fix you right up.
Match the capacitance on the capacitors. Go over voltage if you can, and still have them fit.
IE - it's not a bad idea to replace a 10V cap with a 16V or 25V or even a 50V, but don't replace a 680uF cap with a 500uF or a 1000uF (unless you are SURE it's only doing supply output ripple filtering,
and even then, you should go OVER, not under the uF rating).

Most of the caps that go are 10V 1000uF or 3300uF.

I found some great videos of the procedure (for many Samsungs with the same issue) on youtube.

As you can see, this issue spans plasma TVs, as well as large and small LCD TVs and monitors, amplifiers, computer power supplies and motherboards, and other electronic equipment.
The parts are cheap, and skill required is minimal.
A great parts source is Digi-Key, and you can order the parts online at www.digikey.com
They typically cost under a dollar a piece plus a flat shipping rate.
The parts usually arrive one business day later.
If you watch the third video, you will see that even someone with no soldering experience can perform these repairs as demonstrated by the woman in the video.

This is a common occuring problem what has happend is you have the ylod better known as the yellow light of death. This means the solder on the motherboard has come loose and won't supply the needed power to keep the system running so you need to either send it in for repair which is $110. It's gone for two weeks then back just as good as new

Pioneer media receiver won t turn on


If the light on the media reciever doesn't come on then the power supply in that needs to be replaced by a service tech. If you disconnect the 2 cables from the media reciever and the panel and then try to turn on the panel it should light with red and green squares for a few seconds but will turn off as it needs the media reciever to be connected.
