Did you power it on. Please send me your address and the name of your power company. I'll call them and have someone check the power lines.

Need a model number. But I already know the problem. This is not an easy fix as told on You Tube. Under warranty would replace the panel (TV Screen). Replacing LEDs are next to impossible. I fixed these with warranty. Thanks for asking, Matt of Martins TV.

SOURCE: LG Plasma TV automatic turn off right after turn on

You have some dried out capacitors on the power supply. Samsung has a major issue with this right now and I made a tutorial for that repair in my Tips & Tricks. Your capacitors will not be the same, but identifying them and replacing them will be. Best advise I can give you: Stop using the TV and unplug it until you get it fixed. When these caps go bad, they draw down the voltage they are filtering. I've seen some TVs that had secondary damage because of this. I hope this was of some assistance, best wishes.

Good morning, my LG 55UF6450-UA is turning on & than shutting off a few minutes later. Could this problem be resolved by replacing the Power Supply / LED Driver Board? Please advise. Thanks.

If your LG TV is turning itself off, try the following
  1. Check the AC cord is plugged in properly
  2. Ensure the AC cord isn't damaged
  3. Test the power socket
  4. Reset the TV
  5. Deactivate Quick Start +
  6. Disable the auto power off
  7. Disable the power off timer
  8. Clear the cache
  9. Update your software
  10. Factory reset the TV

Lg 55lh90 no sound

The set itself may have a hard reset--if what happened was a outage--unplug set, box if used, receiver if used and wait a while--plug all back and wait for any and all to come up--reboot to see if it helps or not.

If no sound via any input like a DVD etc check that speakers to set did not get switched to off by that event.

Failing these the set may have a audio circuit problem.

Tv wont turn on

hold the menu and input/device buttons for 5 seconds and it will blink you a 2 digit code
1-2 normal operation
2-3 i believe is short circuit protection = probably a convergence failure
here is a link to my tutorial
http://www.fixya.com/support/r5001731-convergence_diagnosing_convergence
Let me know if I can be of further assistance.
