Re: LG plasma TV turned off, after the picture very light
I think you have a defective power board. the pop sound in coming from the board and giving you a low output voltage. do it yourself price about two hundred for parts.

Common LG LCD TV REPAIR - NO PICTURE OR BLACK SCREEN FIX ... came on good with green light working properlybut still no picture.
Your tv contains protection circuitry that would shut down the tv if the ymain was out. If the ymain had blown, you'd have no sound and just a flashing standby light. My gut tells me you need to replace the Power Supply Board (PSB). I've seen this before and after spending too much money trying to diagnose a ymain failure, I was surprised to learn that when you have sound but no picture, the psb is a gonner. Try ebay, shopjimmy.com or discount-merchant.com for a replacement.
Good Luck!
There will be a fault in either the Y or Z sustain boards, these are responsible for driving the screen 9hence sound but no picture). The popping sound willhave either been a fuse blowing on the board or another possibility is one of the drive ICs on the buffer board has blown. If so it's best to replace the board.
I suggest you guys take your TV's into a repair shop like Sears or Best Buy... The main reason most plasmas go dark is because of decay, but I don't think this is the case. Because what you describe is similar to what happens in LCD's when their back light goes out. Although you can open up and repair the back light your self in a LCD, I would not advise you to do so for a Plasma, because of the hazardous chemicals used in the plasma display plus the fact that plasmas don't use back lighting. And 2 years is way to soon for decay to be a factor. So more than likely a circuit shorted out and the TV has to be opened up to be repaired.
The plasma gas tubes may be damaged or the gas couldve leak out. remember plasma have to remain upright at all times even when transporting them, if they are not you should just set it up straight for about 3-4 hours before turning it on.
call 877-543-8325 this is an LG Executive call center and they will fix this for free. I have a 50" plasma I bought january 2006 which is out of warranty by 5 months. They faxed me and the LG repair shop a 30 day warranty for my tv to cover the repair. Just tell them you heard a pop and in my case the picture is distorted. All they need is the model number and serial number and they should take care of it. No arguing needed.
Our LG 50" plasma tv screen went black after a popping noise but still had sound, after great diliberations decided to take the back off and have a peek!
We unplugged the tv and tested the fuses (there were three we could see) one had blown, the one on the left as you look at the back of the tv it also has one above it. We wrote the code/seriel number down and took the fuse to the electrical wholesalers Maplin and bought a pack of 10 fuses for £1.29 replaced the fuse in the tv and everything now fine!!!!!!
Hope this might be of use to anyone whose lost the picture after a loud popping/snacking noise but still has sound.
