That popping sound is usually a capacitor or "cap". Depending on what board it was on, would depend on what needs to be replaced. Usually its the main "power" board. I would say it probably would be worth replacing as these boards are generally not that expensive. If you take the back of the TV off, you can look at the boards. Caps are cylindrical and are various heights and widths. However they should have a flat top and bottom. Look for one that has a round top or bottom. Do NOT touch the boards though. Caps can store energy long after the TV has been unplugged and static electricity can damage sensitive chips.

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.

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.
