It might be as simple as the fuse on the doubler board.
If you are capable of TV repairs, inside the TV, where the power cable connects to the board, there should be a small glass fuse. Check that to make sure it is not open, if it is, try replacing it with the same amp and voltage, if it pops again, then it is something more serious like a short some where.

I have a Sharp flat panel model LC-20SH4U. The units power LED light is red. No effect (sound or picture) when remote or on/off switch is activated. The LED light slightly blinks.


Resetting the TV
If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:

NOTE:
Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.

Sony KDL 46HX820 turns on, then off and red light blinks four times.


Re: Bravia KDL46EX720. Red LED blinks 4 times and TV wont turn on. What is the problem?

Do a Power Reset.

1. Turn off the TV.
2. Unplug the power cord of the TV from the electrical outlet.
3. Let the TV remain without power for 60 seconds.
4. Plug the power cord back into the electrical outlet. (If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.)
5. Turn on the TV.

If the issue still persists after performing power reset, that may be an indication that the TV needs service. You may refer to this link to locate the nearest Sony authorized service center in your area.

Everything is plugged in, and it wont turn on


It seems even 5th or 6th problem is this. The AC adapter needs to be reset. Unplug it from the wall outlet for 5 to 10 minutes (NOT from the Wii, it HAS to be from the wall outlet).

Considering how often I see this problem, I'm amazed Nintendo didn't address it in their FAQ on the Wii.

This is a common problem with the Wii. As I said, I'm very surprised Nintnedo didn't cover this in the owners manual FAQ, considering it happens almost every time there is a power surge or the power goes out, etc.

Even if it's hooked up to a surge protector, this happens. Power comes back on, but the Wii appears dead. It won't turn on, and the LED indicators won't light. If there was a power surge, or the power went out,etc...anything, this will happen. The problem is with the AC adapter,not the Wii itself.

You need to reset the AC adapter to get the Wii to work again. There is a circuit inside the AC adapter that needs to be reset. Unplug the AC adapter from the wall/surge protector outlet. Don't unlpug it from the Wii, it has to be at the outlet. You have to kill power to the adapter.

Unlpug it from the wall/surge protector outlet, and leave it unplugged for 5 or 10minutes. This will kill power to the AC adapter, and give the circuit time to reset. When you plug the adapter back into the outlet after 10 minutes, the red led on the front should be lit up.

take your tv to technician who can check your power supply, if your power is coming on and off, than a problem is not as big. firstly let him check a ht of a supply constantly, your supply is cutting.

If ever resetting is no effect then the problem is in the "DM board"
The constant blinking green light means that the TV is not booting up. This is a common problem on this set. Hope it may help you; Regards, VOTIT
