LG 50PC55 Plasma - Wont work?!?

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.

Lg 50pc55 plasma- has sound but no display??


Quite possible-----replace all bad ones and also if possible the voltages coming out of that board need to be tested---to be honest other than the caps it sounds like a main board issue. The set may have been run too long with the bad caps.

When i try to turn on the tv it wont come on and then if i leave it a while it will turn on and work fine so i took it off the wall and gave it a clean and now it wont come on at all it is a LG plasma tv


Sounds like either a loose connection suspected from the fault worsening when you moved it, or a dry solder joint on one of the pcbs. It could also be a dry capacitor on the power supply board shown by bulging tops on the capacitor. It could be that when mounted on the wall, the tv was located near a source of heat and this heat helped the low value capacitors to warm up and work. Either way it will be one of these 3 possible solutions.

Can I use any universal wall mount for my LG


Just check the weight and size restriction on the wall mount. As long as the weight and size specs of the TV fall within those allotted by the wall mount, you should be fine.

Panasonic TH-42PX75U won't turn on


Your powerboard is damaged, and need to be replaced.

Sometimes it appear the TV is working again with no problem but it is only a matter of time for the board to get completely damaged.

My 50' LG Plasma made a loud pop and shut off and won't turn on.


warranty not worth the paper it is written on
under warranty it is not a requirement that you fit/ fix anything
the only option is to take it to a repair shop for a diagnosis and quote and then decide if the power hungry plasma set is worth repairing
LED sets use 1/10 the power of plasma units so an upgrade will save money
