SOURCE: TV auto shut off-power indicator light blinking-won't turn back on

You could have gotten an electrical surge that put your set into a shutdown condition and unplugging the set and letting the Microprocessor reset will fix this problem if it dosent blow out the main power regulator as you still or might I say have a regulator IC problem. IF THIS PROBLEM HAPPENS AGAIN MORE THEN A FEW TIMES WITHIN A SMALL TIME FRAME I WOULD HAVE THE SET LOOKED AT BEFORE THE REGULAOR BLOWS SOMETHING OUT!!!!

I have the same problem. The only way to get the TV to come on is to unplug it, but once you get it back on it turns itself off again in a few minutes.

SOURCE: TV on/off light keeps blinking red light/no sound or picture on screen

Here's a solution that I received from an TV expert in another website: "This sounds like a power supply problem. i have seen it several time on your model. i would not keep trying to turn it on it might damage something else in the tv. the reason it is shutting off is because the power supply is putting out too much voltage. a repair cost will range around 300-400. this is a great model and well worth a repair. here is a web site that might help you in finding a repairman.
http://www.nesda.com/locator/state_search.php." <-- $300-$400 is too much! But throwing away a 300lbs TV will cost a lot of $$$ for the towing and dumping too. I haven't decide what to do yet.

Pull the three connectors to the yokes on the convergence board. If the set powers up, it's a good chance the STK392-110's need to be replaced. I fixed one today, and it has been running for 6 hours now.

Tv wont turn on


tried to unplug the tv for a while to reset the power supply and then re plugged and turn it on let see if it will turn on. if still doesn't work and no power at all, at this time you will need to remove the back cover to access the power supply board, then look for a bad fuse or a burnt parts. replaced bad parts with the same value and rating.you can find replacement at www.digikey.com.

I was playing my PS3 and moved it from my tv upstairs to my tv downstairs. After plugging my PS3 in my tv downstairs, on which it had worked just 1 week previously, my tv picked up no signal from my PS3....


Try this.

Plug your PS3 on either TV. Turn on the backswitch. When the red light in front is on, put your finger on the on/off button in front AND KEEP IT THERE. You will hear some beeps; don't worry about that. Keep your finger on the button until the front power light goes red again. This resets the PS3 video settings. Turn the PS3 on and the TV should pick up the signal.

Hope this helps. Keep us posted.

I took my PS3 to a friends and we used an HDMI cable to hook it to his tv and when he brought it back to my house and now it wont work, i use the red ywllow and white audio/video plugs. why wont my...


hey, when you used the HDMI cable at your friends place, the PS3 display got set to 1080p. to bring it back to standard definition (red, white, yellow wire), follow these steps.

turn off you TV and PS3

turn on your TV

With your PS3 turned off, press and hold the Power button on the front of the PS3 for about 10 seconds (the system will beep as normal as it starts up but after 7-10 seconds it will beep again). The video settings should now be reverted. Doing this will also reset any theme settings.

Now you should be able to see your PS3 menu on the TV.

Happy to help :)

Power went off and came back on last Friday and now tv wont turn back on


Have you got a stand by light on, or is tv dead totally.I would Check plug fuse if dead, My suspect would be power supply capacitors drying out (had this fault recently with friends tv) this caused tv to be working sometimes but eventually stuck on standby. Capacitors are cheap but not a job for the novice.
You could ask local tv shop for estimate

Had the ps3 working fine, plugged it into another tv and nothing, the tv wont pick up the signal.. went to plug it back into the 1st tv and still nothing


Try resetting the display back to standard definition -

Turn the PS3 off into standby (red light on)
Press and hold the power button. It will beep when you first press it, then beep again 5 seconds later. Let go of the power button when you hear this second beep

Wait for the PS3 display to reset

Hope this helps

The picture wont come on


First make sure to hit the menu button on the TV's remote and if nothing is there then friend while the set is on turn a bright flashlight on and shine at angle into the set push the TV menu button if you can see a image then your back light is not working.
You can also check the transformers they are close to were the wires plug into the panel, make sure all transformers read the same amount of resistance if not you have found a bad one. Now you will have to check to see if the power supply is sending 24v to the backlight, if not the power supply is bad. Cost backlights around 150.00 and power supplies around 100.00. Well this should help you friend.

Tv wont turn on, i got it last april, it worked eversince,


First off, try a power drain:
Unplug the TV's power cable so it is not grounded to the house.  Then press and hold the TV's own power button in for a minute.  Plug the TV back in and see if it works. If it sill won't work, are there any visible LED lights you can see in the back of the TV?  You need to determine if the TV's power supply is shot or the TV's mainboard.  Service would likely be required if the TV still won't turn on.
