Re: LG 37LG3000 repacement or screen repair
Unfortunately, the LCD panel will have to be replaced. The LCD panel along with the labor could cost close to $1000 to replace. In most cases it is cheaper to just replace the TV. The manufacturers warranty will not cover damage usually. Sorry.. Wish I had a better answer

Sadly, the screen is the most expensive part of the TV. The replacement screen would cost more than the TV is worth. Shopjimmy.com is the only affordable place to buy the replacement screen, But, they are out of stock. Usually, the screen cost around $250 to $350. Any other website will cost an arm and a leg. Buying a new TV would be best at this point.
There is a circuit board that needs to be fixed or replaced inside the TV. This isn't something you'd want to try unless you have that type of experience. A local TV repair shop will be able to get the service manual and determine exactly which board is causing the problem. As long as the part needed for the repair is still available from the manufacturer, you won't have any problems other than having to pay for the repair out of pocket if you didn't purchase an extended warranty.

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.
If the Video (Picture/Pix) is gone but you can hear the Audio (sound), then it could mean the YSUS PCB Assembly is gone/kaput/finish. Can replace the PCB, not repair the PCB due to timing circuitry involve. Cost maybe roughly $500 depending where you located. The PCB is located on the left hand side of your TV when you are facing the back (Back open). Might find 3-4 brown flex membrane connecting to the plasma panel. The PCB has a silver or black aluminum heatsink (big) on it. Good Luck.
