well it looks to me u need a new tv....all the details u give are pointing that ur picture tube is gone.....but call LG help and costumer line and ask them......u may get away from it to get a new tv
make sure when u get a new plasma to extend ur warren tie to a max o 3 to 5 years and if this would happend u get it repaires for free.......cost for a new screen app 1000 to 1500 dollars

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.

the z sus board is the board thats on the right next to the right speaker looking at it from the back, and you can get it at ebay cheap.

Same problem...not solutions so far from what i can see. just a popping type sound...picture GONE...sound still there....had it for 2 years and 3 months....warrenty was for 2 years...eh hem...it figures.

I know you already replaced the board, this is for future searchers. If you heard a popping sound, then the picture went out, there is a 32 pin Sanyo module that goes bad on the board. That's probably what caused the fuse to blow. Replace the module, then replace the fuse. The module is less than half the cost of a used board. Since this was a popular model TV, there are lots of replacement boards on the used market.

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.

ysus pcb that supplies voltage to the panel is faulty

sounds like it may be a software upgrade
