I would try leaving the TV unplugged for 30 minutes to let the TV reset itself.
If that doesn't work, most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.

Blinking green power light & shut down


There are (4) 1000uf @35V capacitors all together on the DM board that need to be replaced some models have 1000uf @ 16V but they are all right beside each other and all rated at 1000ufs the voltages will be stamped on the capacitor along with the uf ratings.

Tv will not turn on but it constantly blinks and will not stop


You need to change the seven capacitors on the DM power supply board (inside the metal case on the left where your DTV tuner connects)They are 1000 MFD 16 VOLT capacitors and the tops are probably bulging outward because they are leaky- this is a common problem.When you lost power,the TV had to reboot itself but because of the leaky caps it never will and the green light keeps blinking.As long as you never lost power or unplugged the set the TV would of still worked.Once you change the parts and plug the set in the light will blink normaly for about a minute and when it stops blinking you can then turn on the TV.
