It all depends what has led up to the problem, however if there has
been no indication of something going wrong,ie. picture getting dimmer, the most common fix is to reset.
First just check all cables are firmly connected. If that does not work then....
Unplug tv, disconnect from cable box, satellite box, any receivers.
Also turn power off to them as well.
Connect everything back and turn on.
Here is a video of other generic problems that can go wrong on any
tv that leads to sound with no picture.
TV Has Sound But No Picture Troubleshooting Guide

It sounds like it's the inverter panel which lites the lcd back light.
If it's under warranty, try to replace it, or take it in for svc.
SOURCE: LG plasma tv made loud popping noise
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.

SOURCE: LG 50inch Plasma received loud sound then went black
My friend's LG 50" plasma tv has the same problem and it cannot light up. The picture and sound are working fine. But the brightness is too low. It is purchased 2006 too and out of warranty. So I opeend up and found 9 capacitors 3300uF 10V on the power module at the middle of TV are popped. I am planing to replace all of them. They are available at digikey.com. I think this model's power module has design flaw. The cap rating may to low. 10V? Stay tune to see what happen after I change the all the caps.

Hi there,
I seem to have lost you. You can re-connect the chat if you need to, but this is what you really need to make this work correctly.

Connect this to your Mac, then connect an HDMI cable to the port on the adaptor and the other end of the HDMI to your TV. You will then have audio and video from the Mac on the TV, with only one cable.
If you have any questions here, we can continue the discussion here if you wish.
