SOURCE: power & OPC lights keep

That signal the fact that the power source is in protected mode - a component has failed in the tv and now acts as a short. When the power source tries to start the failed component starts to draw so much power that the voltage drops; this trigger the protection system of the source that shuts it down to save it from frying.
To fix the tv you will need to open the tv and test the voltages on the output rails of the power source to find out which one is triggering the shut down. Then just follow it to the failed part. This requires a good electronics experience.
In your tv the most usual part to fail is the sound board: the radiator on the audio amplifier is undersized so the amplifier overheats and fries. The sound board will have to be replaced - a $250 job at a repair shop.

SOURCE: tv won't turn on

you have to shut your main power down at the breaker box. It can be off for about ten min.

I hope this works for you.

SOURCE: Flashing green power light with no picture

9-if the tv is still under the manufactuer warranty i would definitly give them a call. If it is a Sharp tv I would call the 1-87-BESHARP. I would also try unplugging the tv for at least 2-3 minutes and seeing if the tv will reset itself. Usually what happens with these tv's when the light blinks it locks the tv as a security issue. If the unplug does not help it will more than likely need service to get this fixed for you. The call line hours are M-F 7am-7pm S-S 9-5 and they will be glad to help you from there.

Green light on mittsubishi tv 65inch won't quit


It is the set's brain trying to boot up. (not unlike a computer) These sets if unplugged and power applied should blink 70 seconds and then go out and then can be turned on.

The model number will determine my answer/suggestions=

Models beginning with WD are nasty if this problem.

Models beginning with WS are not quite so nasty to deal with.

A full model number will tell which you have.
