We were watching our TV last night and it shut itself off and would not turn on with the remote or on the tv itself. I moved the plug to another on the strip and it turned back on. Now this morning it shut itself off again and nothing I do will get it to turn back on..even trying a different strip from a different outlet.

Re: TV shut off
The set is going into shutdown,there are a few reasons why the circuit is being activated,excessive high voltage,excessive volts supply(poor regulation)no screen voltage or a secondary supply is missing,if you are familiar with tv service you have a few places to check,you will need a volt meter and a soldering iron and the squematic diagram to locate the different circuits mentioned,if you are not too familiar seek the assistance of a servicer.Let Us know if you need more information.

It can Have one of 2 Troubles, The Inverter Board is Defective or the Power Supply has bad Capacitors. I found 3 Capacitors known to go bad in that set. Replace the 10 Volt Capacitors with 16 Volt Caps and they will last forever.
I don't know what might have been making it turn on in the middle of the night. It it keeps turning off while you are watching, you might want to check if:
1) someone is accidentially hitting the SLEEP button on the remote. The TV will turn off automatically 30, 60 or 90 minutes after the sleep button is hit. It can also get hit if you set the remote between seat cushions on the couch and someone moves, etc.
2) Does the TV get enough ventilation to allow heat in the TV to circulate away from the set? Drapes, tight cabinet, etc. The temperature sensor may turn the TV off automatically to protect the TV.
3) Your power cord is not well plugged into the wall or you might have some issues with the wall outlet - expecially if it is an older home (before 1980). Any wiggle of the cord may cause it to disconnect for a very short time - the TV will shut off.
4) This Brand is only available through BEST BUY and this model has a 1-year warrentee. The manual says to call 1-888-BESTBUY for service.
Sometimes when you unplug the set ffrom the wall power or a while 1-2 minutes, and then plug it back in the problem will resolve itself. The DVD may eject. If it does, check it for damage, warping or dirt. If this does not fix it- you probably should take it to a repair center.

This TV has reached the end of its (short) life. Needs to be replaced.
You can try looking at what kind of TV it is, what model, and look at the manufacturer's web site, check for the manual, look up what it means when the green light flashes. Might be a code that means something but I think the TV is dead.
This may denote a proble in either your switching powers supply or your Horizontal section derived high voltage power supply. These are both very dangerous sections in your television. My next question is important; do you have a background in electronics? If not I would not advise you working on this problem yourself and that you take the TV to a repair shop for servicing. If you do have some background in electronics, I would like for you to make the following obeservations:
What was the TV doing (it actions)prior to it going out?
Did you hear any sounds before it went out like buzzing or crackling?
What do you hear when you try to turn it on now, clicking?
These questions are just to develop some background into what might be happening to your set.
