LG LCD wont turn on?
Blank or black screens?
A lot of times when your screen doesn't want to turn on, you have bad capacitors. Recently my 47" LG LCD TV started acting up. No sooner than a month passed and my TV was pronounce useless. All I got when I pressed ON was a black screen and a red power light flashing. The red power LeD would stay blinking forever until I pressed OFF and then it would stay a solid red like most electronics these days. So I made a few phone calls and did a quick research online and found out that it would cost over $500 to fix my TV which just so happened to be a month after my warranty expired. I did some more reasearch and realized I can fix it myself for under $30. The problem with my LG was the capacitors. A quick opening of the back panel will show you if this your problem. I made a tutorial video on how I did it.

You should have included the part numbers for the capacitors that are located on the board next to the capacitors just in case other peoples capacitors didnt swell but where still bad.Radioshack's capacitors arent known for there quality a better place to get them would be digikeys.That spewing stuff is called electrolyte.Another thing you need to be aware of other than voltage and farad rating is temperature most caps are rated at 85 degrees but some are whats called high temperature caps that are 105 degress,85 degrees caps wont work for long in the place of a high temperature cap,but a high temp cap will work in place of a low temp cap.This little cheap piece of machinery here would have helped you greatly with taking the caps out http://www.radioshack.com/product/index.jsp?productId=2062731
