We have a 1 year old 42" LG LCD TV. It currently hangs from the wall. The power just all of a sudden went out and won't keep power when we try to turn it back on. Not sure what happend.
No thunder or lightning or any power surges either.
Hello. you are not alone, this is a common problem with alot of new lcd and plasma tv's since they operate with high internal voltages the circuts have built in protection. any slight power fualt or short in the circut will cuase a sos or shutdown. may be a number of different reasons or even a shorted fuse.
it needs to be checked you have a power issue.
some models if there is a blinking led the number of blinks indicates the fualty area.
your tv needs service.

The tv power supply board is the causes and the problems,it dead.The the board,where the power a/c cord plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.
First you get the wall hanger. Screw one part to the wall. And then screw the other part to the TV. then you hang the TV on the part screwed to the wall. Hope this solution has been helpful?
I have had the same problem off and on with my 47LG70 for months. When the "popping" noise happens, the blue light in the corner stays on, so I know the tv is still on (sometimes I still have sound, sometimes I don't). Sometimes the screen goes black, but other times it is blue. If I turn the tv off then on again, it might stay on for seconds, minutes or hours. It's been very frustrating.
This seemed to happen right after I got my new Comcast box, which came with an HDMI 1.3 cable. I read somewhere online that this tv might not be compatible with that cable, so I unplugged it and am using component cables again. I just did this today, so I don't know if it will work, but so far the tv has been on for 30 minutes with no problems.
I'm pretty ignorant about HDMI compared to component cables. I imagine I will not get as good a picture with the component cables, but I am willing to sacrifice quality if I can just get the darn thing to work. Mine is also only 18 months old.
Hope this helps. If it doesn't, maybe someone else out there can help us both.
I had mine for 2 years and the main board went out. Cost 650 dollars to fix. Its been less than a yr and a half and it went out again. Selling it on ebay for parts...
I have the same problem, I just spoke with LG Customer service. They had me unplug the power cord, hold down the power button for thirty seconds, plug back in and turn it on, this DID NOT work for me, but maybe it will work for you.
Good Luck! Mine is going to a service shop, maybe what they tell me I can post and it will help you if you have not gotten your tv fixed yet!
