Hi, this means you have a short somewhere in the power supplies, this type problem is very difficult to diagnose without removing the back cover and seeing which diagnostic led goes out first, once that is determined you can get the shorted part replaced, this will not be a do it yourself repair, you can check the led`s as I said to see which goes out first but all that will tell you is which power supply has failed, video-tek

Turned itself off. I turned it back on and power button blinks green for a few seconds then blinks red continuously. red light by card reader blinks red about every five seconds. No picture, no sound.


unplug it from power source completely 15 minutes then plug back in with NOTHING plugged into any of the ports. If it boots back up then does it again later it make be something plugged into a port causing power to back feed into the boards. I had this same issue on my plasma last year ended up being the xbox360. After this if it still wont power then your power board maybe bad.

Vizio vw37l hdtv20a standby light on but wont turn on


you either have a faulty power supply or faulty main board. Vizio power supplies on the older sets are pretty decent. It's usually the main boards that go. These older main boards tend to be pricey so it may be better to buy a new set.

Hi,


Might be some problem with adapter. verify output voltage of the adapter with multimeter. If no output then replace your adapter.

AKAI 32" LCD HDTV WILL NOT TURN ON


The only solution at this point would be to get the power supply repair since new boards are not longer being manufactured. In about 95% of the time if the LCD doesn't power up or turns OFF by itself or need to be unplug for some time to make work again; those are the symptoms of a dying or defective power supply.
I service these power supplies, for more info write to jah2mil@hotmail.com

I can't get my tv to turn on... nothing but blinking red light


Dont know if this will work for you or not, but my brother gave me his because of the same problem. It would power up and a green light would come on, then after 10 -15 seconds it would change to a red blinking light. I plugged a usb cable into the service port on the side and left the other end unplugged. Then plugged the tv back into the power. i took a small screwdriver and ran across the contacts in the end of the usb cable until both the red light and the green lights came on. I did this several times listening fot the clicking noises in the TV. after doing this for approx 20 seconds, i pressed the power button and the TV worked fine. 5 days now and no problems. Only thing I can think is I somehow reset the software and now it is working fine. Hope some of you can figure this out and give it a try. if the TV is just sitting, you have nothing to lose

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
