You can try unplugging the tv and wait for a couple minutes and then plug it back in... I just did this and now the television works again.

Yep, the inverter transformer on the Power Supply Board burned out. It's one of 5 inverters that powers up the screen.
If one is burned out, it will not have enough juice to power the screen and goes into protection mode like it's doing right now.
You'll have to replace the POWER SUPPLY/BACKLIGHT INVERTER BOARD. The cheapest place runs for about $90.
I'm not sure which one you have, there are 2 different boards for that TV. The board number should be in white on your board.
Here's for the BA8AF0F01031
And here's for the BA8AF0F01032
It's definitely cheaper than buyig a new TV. That what I did to fix mine. :)
If you throw your old board in the trash, I would like to keep it for research if possible. Here's my e-mail: firstname.lastname@example.org

Well, it's hard to say what part needs replacing. It maybe the MAIN UNIT board, LCD CONTROLLER board, or the SIGNAL board.
The cheapest way to fix it is have a repair shop tell you which board is bad. Then replace the board yourself.
Here's the best place to get parts for it at a decent price:
Just look through this site to get an idea of what parts a going to cost. I know the repairman would charge double for the same part plus labor to install it.
That's the best advice I can give you.
The TV is defiantly worth repairing than replacing it.

The TV is on protect mode.
Try first leaving the TV power cord unplugged for some times, let say one hour or so.
Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.
If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.
The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.
1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.
2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.
If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.
If you are in situation 2 , then there is an internal fault.
Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.
Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.
If under warranty contact the manufacturer ringing the number on the user manual
If you want to repair at your own expenses, just locate any good qualified repairer.
