Question about LG Televison & Video
Lg utra slim 21 inchs was brought to me for repairs when I check it, the fuse was ok, diodes are all ok and resistors, my problem now is am thinking maybe it the STR w6754 and the power capacitor of 450v 330uf or the transformer. The tv on but goes back off, it just make little sound. And the relay click back again

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.

Sounds like a overheating issue. Try facing a large fan blowing across the back of the unit and see if this changes anything. If it does, it might help to blow the back out with compressed air as dust might be helping it overheat.
