Sometimes you can call the company and they will instruct you on a reset button combination on the TV and wala FIXED! My friend had the same problem on his tv. Or maybe your pcb board may have some blown caps.

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.

This set has LG insides, it will have failed on either the Y-Sustain PCB or the Z-Sustain PCB.
Quite common.
Repair estimates should be $250 - £350 depending on which has failed.
Stick it on eBay, it will fetch good money faulty.

Most likely the TV has a power supply related problem. The most common problem are the power supply for the screen itself. Most manufactures call it a Backlight Inverter Board. Something you may want to look at for your problem. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.
You have a few choices:
1. You can try leaving the TV unplugged for 30 - 45 minutes so the TV can discharge and reset itself.
2. If by chance the TV is still under warranty, go that route.
3. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.
4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.
