First, I would try leaving the TV unplugged for an hour so the TV can discharge and reset itself.
If this doesn't work, it maybe something simple like a blown fuses inside the TV that needs replacing.Radio Shack or some electronic store will carry the fuses.
If the other two ideas doesn't solve it, we're talking about a power supply board related problem. I can't actually look at your TV over the internet. But, the most common problem with flat panel TV are the power supply board for the screen itself and the main power supply board for the rest of the TV. Commonly a bad capacitor or transformer will be on the board.
If you have some electronic experience and want to repair it yourself, you can sometimes find a Service Manual for your TV over the internet. Normally, costs less than $20. It will have diagrams, schematics, and part number list for the TV.

After power surge panasonic hdtv projection tv model # PT-53WX42F wont come on red light flashes


Bobbie, It dose not sound like surge protector was real effective, the TV will have to come apart to diagnose what has all blown, capacitors, boards etc. Google search can help show how it is done.
Enter all your TV's info, will not power on repair.

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.

Had power surge. Tv was on surge protector. Now no power will come on and just makes a buzzing sound.


Have you tried plugging it in without the surge protector? I would wager that either a) the surge protector needs to be reset/turned on and off depending on the model or b) either your TV and/or surge protector have been damaged by the power surge.

Try plugging the TV straight into the outlet and see if that helps.

I turned off my seike tv model number se321fb and now it wont turn back on? the surge protector has power how do i get it to come back on?


Even though the indicator light on your surge protector is on, the surge protector outlets may not be working. Test it by plugging in a different electronic to make sure it still works.

It could also be a problem with your remote, such as dead batteries or that the remote is no longer programmed with the correct codes.

Here are a couple of troubleshooting checklists that can help you identify the problem and what you can do to solve it:

Remote not working
No picture on TV

I hope this helps!

We had bad weather lights went out ..had tv plugged into a power surge plug ...now that i have power back tv wont come on


Some will say a surge protector will save electronics. I can tell you they may not help at all. A power surge is extremely fast and can over ride the surge protector. If you think you can repair this TV, I would certainly remove the back cover and inspect. Occasionally the only problem for repair is to replace the main fuse. Remember, this happens rarely. Most cases after a surge the TV will need to be inspected by a TV tech. Almost anything, in a power surge will damage the TV. There is no certain area that will not be damaged, expect it any where. Thanks for asking and show all hands of support!

Does my samsung tv keeping turning itself off because of not having plugged it into a surge protector or is it more a fault with my tv


It is a fault with your power supply module actually inside the tv...take it to a local service center or if its under warranty take it back. surge protectors help prevent issues like this occuring due to damage to the power supply from surges but not having one wont cause these problems unless it has recieved a surge.....in future i would use a surge protector on all your expensive appliances, surges and power fluctuations are very common in mains power i live near the mines and we have power problems all the time!! hope this helps,ben

Tv won't turn on


I suggest you unplug the set for about 15 minutes and then plug it in and try again. Sounds like you may have had a power surge/bump in the middle of the night. Althoguh you are using a surge protector, doesn'r mean the devise hooked to it can't lock up during a power surge.( Surge Protectors are an insurance policy only, not a garrentee ). If unplugging the set and waiting doesn't fix it, it will need to have the power supply section of the board repaired. Good Luck
