I was watching tv a few nights ago and then I heard a loud "popping" sound and my tv just just off. Now when I try to turn it on it sounds like its going to start but turns off instantly. Does this twice...


the same thing low voltage supply, if there is no blown up capacitor then hold all supply capacitor then shake it a little while, if you ca notice that there's a lose of that capacitor remove it,it might the leg is lose or cut already.

Lg 42 plasma - loud bang/spark smelly smoke and small flame inside.


It is a short circuit caused by some components and/or power capacitors. This may need assessment by a qualified service technician.

You will find that the power supply has failed and is no longer supplying the VS voltage that the screen requires to produce a picture.
Call a specialised engineer that is authorised to work on your make ot TV.

I have a LG plasma 42PC1DG, watching tv loud pop then no picture but still have sound, left tv unplugged for a while still no picture?


probably the pop was a fuse blowing inside that only controls the lamp should be an easy fix but open the tv at your own risk

Pop and no Picture


If you are not getting sound nor picture, it could be fuse or power supply.
If it is just the picture, it is a burn capacitor or main board problem.

Unfortunately, that board is the inverter board. And for this model the inverter board is only supplied with the the PDP panel. The panel is quite expensive, here's a link if needed:
