Power won't stay on-power light comes on and then right off again-

These blinks to standby light are fault indications, called blinking codes. From the number of blinks occur at one time switch on, you can get an idea about the faulty circuit stage inside it. Count it. Visit this site. It has details about blinking codes to many brand televisions.http://electronicshelponline.blogspot.com/Pull up older posts there, either by its left side bar, or see it in Timslide option

Check and replace its main power regulator board. It might be faulty. Normally there is no repair to these boards. Card base replacement should be done.

Sounds like a power board reset switch gone bad. Have the power board replaced.

Those are all really common symptoms of the alternator going bad on those cars. I would have it checked to make sure it's charging properly.

If it is a 3.8 engine change the crank sensor,they go bad on the 3.8 engines.

I also had blown capacitors on my power supply. You can see when they're bad: the tops split or bubble up like a dome. I changed most of the caps, just to be sure, and it fixed the problem. Careful of the larger capacitors. They stay powered for some time and can shock you pretty badly. Good Luck

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 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 TV 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 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 positive it's only doing 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.
The parts are cheap, and skill required is minimal.
Cpacitors are less than a buck a piece typically if you order online from a place like www.digikey.com plus shipping, and they usually arrive next business day.

On the older fords the theft module has 2 plugs in them. You can disconnct one of them, I believe it is the right one , and disable the security system. Finding the module is the hard part. most are located in the middle of the dash.

1. Hold [menu] and [vol-] button on the side of the TV
2. while holding these, press the [power] button on the side of TV (NOT remote)
3. blue light comes ON and stays ON
4. wait 10 seconds then let go of [menu] and [vol-]
5. wait another 30 seconds and some type of picture should appear

I think this is right. I got it from the JVC call centers guys so sorry if I missed or messed up a step.

I have the same problem. The next stage is that the picture won't come on at all and the blue light will constantly blink. I think the light source is bad. Noit sure though.
