Facing TV Problems? Ask a TV Technician.
I'm reviewing your details and will reply shortly.
How long have you owned the LG set for please and are there currently any signs of life on the TV at all- or does it appear completely dead- as if it were not even plugged in?
Okay offhand no signs of life at all would indicate a premature hardware failure in the set in most cases- and generally require repairs be made to fix the issue.
However it's worth it to try a hard reset, as sometimes the processor in the TV can simply have locked up.
The first thing you would try, is disconnect the set from power, then press and hold the power button on the TV itself (not the remote), for 10 seconds and release. Then plug the set back in, and also check that the power cord is connected tight at the TV as well. Press power once, and see if the set powers up normally. Try this procedure up to 2 times, and please let me know what happens.
There's nothing else on a user level you can try as this directly means the TV has prematurely failed and requires repairs. This is not uncommon these days with newer flat screens and the good news is you're still under warranty. The next step is to contact LG and start a warranty repair ticket on the set I'm afraid. I can pull up that info for you now.
You will need to either contact the retailer where you purchased the TV, or use the link below, scroll down the page to "Repair Services" and then click and follow the on screen instructions:
