Customer Question

I have an 60" LG 4K ultra hd smart tv, 60UB8200, I was watching the NBA finals Thursday night and my tv went blank, the screen stays blue/ grey when powered on but nothing will show up on the screen, and no sound. Any idea what is going on? The unit is less than a year old.

Hello and sorry you're having problems. If you shut the TV off and turn it back on does the LG welcome screen display on the set? Also if you grab the original LG remote and press MENU does the MENU display please?

Are you still with me here?

Expert:  Aric replied 5 months ago.

I'm simply trying to find out if the issue is the TV itself or the cable box simply needs to be rebooted. If the LG welcome screen displays, then it's likely that the problem is your cable box and you would simply want to reboot it. However I'm waiting on your reply to determine that.

No nothing come up, it powers on no sound. Nothing comes up on the screen
Expert:  Aric replied 5 months ago.

Okay that's bad news since the LG welcome screen and the MENU items should always come up unless there's a hardware failure in the TV. Right now, that's what it's looking like here. Given that's the bad news it's also good news that you're still within warranty. The part of the TV that causes this is the Mainboard, and will need to be replaced by LG under their warranty in most cases.

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 with the LG logo on the screen. Try this procedure up to 3 times, and please let me know what happens.

Okay

Simply reply back when you're done and we can proceed.

Are you still having the same problem?

Expert:  Aric replied 5 months ago.

If so, then unfortunately this indicates a premature failure with the TV that does require repairs. In this case you would need to contact LG at the link below and setup a repair ticket on the set. I'm sorry for the bad news here, and realize this is frustrating. However please keep in mind that I'm only trying to help you and don't have any control over the fact that the TV has failed.

One last ditch effort would be to leave the set unplugged for several hours in the HOPES that it resets. Other than that. there's nothing else on a user level you can try. Do you need further assistance with this?

Expert:  Aric replied 5 months ago.
