Our LG 50" plasma tv screen went black after a popping noise but still had sound, after great diliberations decided to take the back off and have a peek!
We unplugged the tv and tested the fuses (there were three we could see) one had blown, the one on the left as you look at the back of the tv it also has one above it. We wrote the code/seriel number down and took the fuse to the electrical wholesalers Maplin and bought a pack of 10 fuses for £1.29 replaced the fuse in the tv and everything now fine!!!!!!
Hope this might be of use to anyone whose lost the picture after a loud popping/snacking noise but still has sound.

These problems are probably bad inverter board that supply the inverted voltages to the back lights. It also could be a failure of the back light itself. This problem should be taken to a service center, where they can test the inverter board and the back lights. You can got to the website of the product and check out the frequently asked questions to see if your problem or similar one have been posted and answered. Hope this helps you with your problem.

This is all I could find on this model:

The board you want may not be available except with purchase of the display panel--nasty but some brands do exactly that.

No display issue


Red means it is going into shutdown because something is wrong.

It will not come on again until problem is found and corrected.

Hello sir, looks like your LCD inverter board is toast. this board is responsible for the back lighting of your TV, if this goes so as the lamp. your screen is blacked. Have this replaced by your dealer or check if they have service.
