Why does my LG tv seems like it need to warm up before it will accept HDMI signal?


Sounds like a capacitor fault. They can be intermittent when cold, but will work okay when warm. Eventually though they will fail.

This is your advance notice to get the set either repaired by the manufacturer or a local TV shop.

The tv turns itself off after 5 minutes being turned on


There can be several causes for this, few of which you can do anything about. However, a few things to try.

1) Replace the batteries on your remote control.
2) Try resetting the logic functions on your tv by unplugging it for a minute, then plugging it back in.
3) Try covering up the infra-red receptor on the front of your TV to see if you're getting unwanted signals from the receptor. taping a piece of foil over that area is perfect. If it doesn't stop after doing these two things you'll probably need to take it to a shop.
4) If this does stop it, then look for unexpected signal sources. Have you added a remote control extender? Added a new device to your audio-video system? Changed to a new remote?

Good luck with your problem...I hope you can work it out.

Power turn off after 45 minutes to 1 hour used


Check the "Sleep Timer" settings. If set to 45 minutes then TV would automatically turn itself off 45 minutes from being turned on. The variance in the "on" times is due to the TV turning itself off after not getting a signal from the remote for fifteen minutes.

Good luck,

''no signal'' message on blue screen after watching for 10-30 min


First try another signal input like a DVD player or other source, is the signal displayed ok? Then you have lost the signal on one input from whatever the device is.
