Gpx 48 inch will not power up after power loss


Has the power come back on yet?....just kidding. You might want to unplug the TV from the wall and let it sit for a couple of hours. then plug it back in to see if it will work then. If it doesn't, take the back off the TV to see if the fuse on the power supply board is blown. If the TV has some years on it there may be some capacitors on the board that have failed.

I have a 50" panasonic plasma tv. Model# TC-P50x5. I had unplugged it and went to plug it back in and the tv will not come back on. There is no red light on the tv or remote. Can someone help me please.


power supply module is known to go bad on flat TV's, if you change it make sure you buy the upgraded model, because same model could go bad soon again. but I would check power to wall outlet as first option. and power cord as second.

SOON AS I TURN MY TV ON IT SHUTS RIGHT BACK OFF


It sounds like a repair is required, but to confirm:

With this model, you can try unplugging from the wall for at least thirty seconds, then plug in and switch on. (That's if you haven't already).

If that doesn't work, there is a fault causing the power supply to self protect and shut down again. Repair will be needed.

Tv shut off, and wont turn on. It flashes when you press the power button. NO clue at what is wrong.


is the tv on a power strip? unplug the tv from the power strip or wall outlet wait one minute then plug back into the wall outlet and not a power strip. TV should power back on.

Have power cord plugged into asus eee machine and wall outlet. light has been blinking all day. when asus eee gets unplugged it shuts off.


lets try this ---

* turn of your computer
* remove the plug from your computer.
* Remove the battery from your computer
* Let it sit for 3-5 minutes
* Replace the battery
* Plug your computer back in (Make sure the wall outlet is working as well, seems simple, but have seen it before)
* Let it sit for about 3-5 minutes
* Boot your computer
* go to
Start -> Control Panel -> Power Options -> Power Meter
Note the Total Battery Power Remaining

* Let your computer sit for 15-30 Minutes and see if the Total Battery Power Remaining has gone up.

If so problem solved

if not you may be time for a new battery.

Hitachi 42HDS69 42 in. Plasma... Problem


Describe the past - How did it fail? One day or acting up for a while? Could be a weak power supply - a bad capacitor on a power supply too. Look for popped up capacitor top inside.

LC 32D43U power and OPC green light flashing set does not come on


hey i have had the same problem but i unplugged the tv for awhile about a half hour and then plug your tv into a different wall outlet if you can and should work. It worked for me, i had it plugged into a surge protector then i unplugged it from there, let it sit of half hour then plugged into different wall outlet and worked. so try that and see if it works.

Red light bflashing


Sometimes a power surge will cause a projection back TV to shut down and flash like that. If you unplug it from the wall and let it sit for a minute and then plug it back in, it should reset itself. If that doesn't work it will probably have to be serviced. If it does work, make sure you get a nice surge protector so you don't fry your TV.

Toshiba TV/DVD combo turns on then off again.


try letting it sit for 15-20 minutes unplugged from the wall and maybe try another outlet depending on if u got plugged in to a power strip, possibly pulling to much power from that perticular outlet.
