Y Sustainer problem. However, normally they have to change both Y Sus and Z Sus boards at the same time. If you lucky than it's just a fuse on the Y sustainer blown (the chance is very rare) otherwise the IPM (Intelligence Power Module) on the Y/X sustainer board is short. more then likely if you can get the IPM off of the board you will see that the components are shot, that is the popping noise you heard. shopjimmy.com has these boards some are cheap some are not...good luck

My Sony plasma tv made a pop sound and now picture is dark.


You will need the y and x sustain boards replaced, possibly the buffers. very expensive repair. you can replace one board but its best to do all of them.

42'' lcd turns on no picture/menu


Your tv is being attacked by electrical surges which seem very violent and has already damaged some logic controls. Please invest in a AC filter which will protect your tv from such spikes....... but first you need to get your tv serviced from the electrical damaged it has already suffered.

No picture but has sound


The problem can be caused by a bad sustain board (Ysus Zsus) , the popping sound is often caused by a capacitor blowing up.
The TV must be taken apart and tested before eventually replacing sustain boards.

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.
