    The screen went black and the TV won't turn on- instead of a green light coming on when you turn the tv on, it turns green, then back to red. I disconnected the power source to try to reset the tv. I didn't know if it was a child lock or if there is a bigger problem. Any help would be appreciated

When you hear the Pop, the Plasma display is Gone. There will be two large Capacitors on the power supply board that are swolen as well. Your only course of action is to call LG and beg for assistance, as the Panel itself is a 1600.00 dollar part.

Hi Sharon,

I have the same exact TV and the same exact problem....except today the screen went black and I no longer get a picture from any source. I've had the TV for exactly 13 months. IF you've had your TV for less time, I'd return it.

Hi, I purchased a replacement LCD screen for my SD3500 from Rongstar DigitalInc. Since I've learned they do not have a good reputation and to make matters worse the LCD screen will not function...

I had a similar problem with a Canon camcorder. I replaced it with a new LCD screen from Rongstar Digital, and it works! Saved a $350 camera for $20! However, installing the new LCD was very difficult, and is not meant to be done by amateurs. You have to be sure the tiny connectors and screws are placed exactly right and in the right order. Don't blame the seller if it does not work!

My Canon PowerShot SD880 IS has a black display screen. I cannot take pics now with the black screen, but the display DOES work for pics taken before the screen went black. Please help!

I don't have a solution, but I have the same problem. I found one posting elsewhere that said that this was a "common" problem. That person's camera was under warranty. Mine isn't, but it's less than 2 years old.

I have A LG 50PX4D TV the display has gone off

Most likely the tv has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If its under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.
