Question about Computers & Internet
We have had our tv for 4 weeks now, it is wall mounted and has been working fine. 1 week ago, it wouldnt turn on the stand by (red light) was the only activity, when we swung the tv out and unplugged it (the power socket is located behind the tv in the middle of the wall) and plugged it back in the tv came back on. A couple of days ago again we go to turn the tv on, and the red light is the only activtiy it was as though it had frozen, this time we just pulled the tv out from the bracket and it came back on. Tonight it appeared that the tv had frozen again, except this time the standby light changed from red to amber when we unplugged and re-plugged it. Nothing will work, turning the power off, and back on, unplugging the power supply to the tv, the remote wont even cause a flicker in the tv standby 'amber' light. So we are thinking it is dead. When we turn the power off at the plug and turn it back on, the screen will come on, but not the screen that allows you to even view the setup of the tv, its just like a faint screen? The tv is making the usual noise ie the fan etc as though everything is as it should be. We have checked the manual, it mentions nothing about this in the trouble shooting nor does it mention an amber light in any function what so ever. Ive tried looking on the internet and again nothing seems to appear regarding this problem. Does anyone have any idea what this could be? Thanks Aimee
I had an issue with this TV too, it suddenly started blinking on and off whilst I was watching TV. I turned it off and on and problem persisted. I then pulled the power cable out from TV whilst it was still switched on and waited a few mins and put it back in. It has been 2 days and the issue hasn't happened again.

Both of you are experiencing a power supply that is having trouble turning fully on.
This doesn't bode well since this is signaling a supply critically close to failing.
The fact that it sometimes recovers while unplugged means that whatever part that is critical has time to recover and respond as it should for a while.
If either of you can put a portable fan aimed at the rear of the unit while it is being stubborn, try turning it on again. Don't unplug it before you try this as that may help it recover without having some air to cool it with. If the fan causes it to respond again, then my suspicion is confirmed and you will need to come down on LG since this may be a serial problem.
This can be caused by saving a few pennies on a particular part (electrolytic capacitor) during assembly. These are not critical except in certain signal paths where they are exposed to high frequencies that tend to cause a chemical failure in them.
