TV turned on, heard loud pop. Now screen is very dark.

It sounds like the actual tube / lamp inside the unit has exploded. You will need to either get it repaired at a local TV repair shop or replace the TV. Unfortunately with that unit it is probably cheaper to just replace it.

No picture but have sound

That click might have originated in 2 places: either it was the main relay disconnecting or it was the sound of a capacitor popping. Both are very severe problems - they signal that the power source of your tv has just failed.
Fixing it is a job for someone with electronics experience, if you're not one then call a repairman.

42 inch LG Plasma TV - Lost picture

Most likely what happened is one of the capacitors went bad. When a capacitors goes bad it produces a popping sound. This could be an easy and cheap fix if you find the bad capacitor or capacitors. The bad capacitor will have a bulging top most likely on the power board but could be anywhere.

No picture

The high voltage power supply for the plasma display has failed. It may or may not be on a separate board that could be replaced the owner.

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.
