Bought LG Plasma 106cm in 2008 HD

Plasma TV's are no longer available. Even if you decide to repair....at minimal you will need to replace three boards. Power supply, buffer boards and sometimes a Y board. At its best it may operate for three months and go down. This TV has served its purpose. Shop new. Thanks for asking, Matt of Martins TV Repair.

If you have the same probleme on every chanel and even other sources like DvD.
Then your TV has a serious problem either on the motherbord that controls the image or the Plasma matrice itself.

In this case there will be only one thing to do, contact your retailer or directly the LG customer support.

Hope this helps

You burnt out the backlit lamp. unfortunately there is no easy fix for this. If still underwarranty great, if not... it will cost more to fix it then buy a new tv probably.

This will be your Y SUSTAIN board on the left hand side when you take the back off.
Plenty available on ebay, Very easy fix

This could be a poor connection with the LVDS cable which runs from the main video processing board to the screen, or a fault within the video processor on the main board. Worst case scenario is it could be a fault with the screen itself.

42"plasma tv sound no picture

What have you tested so far?

Is front LED light on?

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.
