More than likely its bad capacitors on the Power supply very common problem with most models. You can get repair kits or replacement power boards from www.tvrepairworld.com

SOURCE: JVC LT-42E488. No picture. JVC logo comes up for a few seconds.

A firmware update might fix it. Call an authorized servicer, explain the symptom.

I have a 55" Panasonic flat screen that won't turn


Try disconnecting all of your HDMI cables and plugging the power cord of the TV into another wall outlet. If this resolves the issue, you may have had a small power surge from either your wall outlet or one of your source devices. It is recommended to connect your TV to a surge protector if you haven't done so already.

Re: tv kdl-55ex620 red light blink 8 times Do a Power Reset. 1. While the TV is off, unplug the power cord of the TV from the electrical outlet. 2. Let the TV remain without power for 60 seconds. 3. 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.) 4. Turn on the TV. 5. When the TV powers on and a picture is displayed, reset the TV to factory default settings.
  • If the Reset message does not appear and the TV turns off and on, begin again from step 5.
  • If the standby light begins blinking eight times, return to step 1.
6. After the Reset message appears, allow the TV to reset. Do not press any buttons on the remote control or on the TV and do not make any other adjustments for 1 minute. 7. Unplug the power cord from the electrical outlet. 8. Allow the TV to remain without power for 10 seconds. 9. Plug the power cord back into the electrical outlet. 10. Turn on the TV.
  • The initial setup screen displays if the above procedures were performed correctly.
11. Follow the on-screen instructions to complete the initial set up. 12. Perform a system software (firmware) update.

Power in house went out. T.V. wont turn on.


Did you have a surge protector on the TV? Have you tried unplugging it for 5 minutes, if not try that. If it still won't work contact your local electrical power provider and start a claim for damages from the power outage.

There should be a surge release button on the surge protector to bring the protector back to normal (should be red in color) Some surge protection devices have this option so just check if your s has it. If that is not the case than I think that you might have blown a fuse in your TV.Might just have to open it up and change the fuse within with the same ratings, but please be careful because do have high voltages so get an experienced technician to do this for you.
Good Luck.
