The Video (Picture) is SEPERATE from the Audio component of the TV. One can work when the other has gone south. From what I see, the Audio controller board may have been damaged somehow and needs to be replaced. Contact a serviceman for details.

    Audio controller board????...Video and audio all come from the same board, no such thing as a audio controller board in LG TV like this, the sound comes from the main board. You can order the main board yourself for about $50 or take it in for service but expect to pay $125 to $175 for repairs.

SOURCE: 42 inch LG Plasma TV - Lost picture

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.

SOURCE: No picture, sound ok

I have a similar issue. Sometimes the entire screen goes black and sometimes only one-half - either the top or bottom half goes black. The only solution we have found is to gently tap the TV (usually the front side) and the picture will come back for awhile. It almost seems heat related as it only goes out after the first 10 minutes of use. There must be a fix to this.

SOURCE: LG 42PC3D Plasma: No picture, good sound

One of the SUS panels will be defect.On these panels you will find several fuses,the panel with the broken fuse must be replaced.
Sus panels are the panels with the big cooling blocks.

SOURCE: my LG HD tv screen suddenly went green. sound is

Hi,
I disagree with info provided, if screen of your LG lcd tv becomes green that means inverter board is working and lcd tv does not have convergence ICs.
Please unplug tv from ac wall socket for minute to get it reset, replug back in and turn it On and check its picture.
If still showing green screen then change input source with remote, if tv shows same green screen on all inputs that means its either lcd panel problem or digital signal processor got bad loacted on main board. Local tv repairman is needed to confirm and fix it.
Thanks.

TV goes off suddenly. Searching for connection.


'Searching for connection' sounds like it's looking for a network link. check your internet connection. If it's supposed to be watching cable or broadcast TV, check the setup menu.
