-TV does not power on. -TV has been plugged into multiple outlets with no success. Was working just hours before. Now no lights power on, nor does the screen.

If the green light is flashing on your Panasonic TV and it won't turn on, it usually indicates that there is a problem with the TV's power supply. Here are some troubleshooting steps you can try:

Unplug the TV from the power outlet and wait for a few minutes before plugging it back in. This will allow the TV to reset.

Check the power cord and make sure it is securely plugged into the TV and the power outlet. If the cord is damaged, replace it.

Check the power outlet by plugging in another device to see if it works. If the outlet is not working, try plugging the TV into a different outlet.

If the above steps do not work, you may need to contact a professional technician to diagnose and repair the TV. It could be an issue with the power supply or other internal components.

I hope these steps help you resolve the issue with your Panasonic TV.

Either your electrical outlet went dead or the power supply in your television went dead. Verify operation of the outlet by plugging a light or other known-working appliance in and, if that is working, unplug your television for a minimum of one hour, plug it back in, and test. If it still does not operate, it will require further service.

•
Press the TV button or ON/OFF button while remote is in TV mode and there's a source of power to the outlet or outlet strip.
•
Make sure the TV is plugged in.
•
You might have tried to turn on the TV during the lamp cool-down. Wait a few moments and the picture will appear.
•
Has the power light on the front of the TV been blinking for one minute? If so, the lamp may be dead. Refer to the Power indicator
is blinking or flashing section below for more information.
•
When you first plug your TV into an outlet, the Power indicator on the front panel will light and blink for approximately 30 seconds
and then go off during the initialization of the TV. This happens only when the TV is unplugged and plugged back in. The TV can
only be turned on after the Power indicator goes off.
•
Check the wall receptacle (or extension cord) to make sure it is "live" by plugging in something else, such as a lamp.
•
Something might be wrong with your remote control. Press the POWER button on the front of the TV. If the TV turns on, check the
remote control solutions on page 53.
•
Multiple TV Setup might be set to the wrong option. Press MENU/OK on the front panel. Select Setup Options, then Advanced
Options, then Multiple TV Setup. Choose TV (default).

Switch off TV, switch off power, remove plug and wait for 48 hours and retry. If problem persists, I suggest it is better to refer it to a qualified service technician, since the back cover has to be opened for investigation/rectification.

Are you getting the red led light? If not, please check the power outlet for any loose contacts. Try the TV on some other power outlet. If the TV does not work still, cool it off for 48 hours, after removing the plug and retry.

Ensure the power outlet has power. Try TV on a different power outlet. Switch off TV manually, switch off power, remove plug and retry after 48 hours. If problem persists, please refer it to a qualified service technician.

Switch off the TV from remote, then switch off the on/off button on the TV, remove the plug pin from the power outlet. Cool off for 48 hours and then retry. If nothing works, better refer it to a qualified service technician.

Well, by process of elimination, it sounds like it may be a problem in the wiring in the house. Your best bet may be to test your outlets for proper wiring (ie. hot/netural faults), and for cycle rate (in hz, 60hz is nomal). I would also look into a surge bar that is built for normalizing power (Often called Power Cleaners). If you have older electrical service into your house (fed from a pole) or if you are in an apartment or condo type building, there may be line problems with the power supply. Basic outlet testers are under $10 and really handy to have around if you do any sort of electrical work, but the surge bars can be quite pricy. I would look at other outlets in the house that have similar AC/DC converters attached (like cordless phones, laptop computers) and see if it works in those outlets. Really a very strange problem, and may go deeper then just the modem itself.

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.
