Anything is repairable as long as the screen isn't damaged.
The sound you heard is most likely was a capacitor that just went dead.
Solder in a new capacitor should fix the problem. It would most likely be on the power supply board somewhere.

You'll need the Service Manual for parts list, diagrams, and schematics. Here's one place for that:

Any other questions just ask.

Samsung 60 plasma T.V. made a loud bang and wont turn on now.


That sounds pretty terminal I am afraid. First thing to check would be the fuse in the mains plug. After that it will need dismantling for any other fixes. If the fuse is ok, then I would start by opening the case up and looking for anything that looks blackened. Start on the pcb that connects to the mains cable.

My Pioneer Plasma PDP-503PU HD went out. It made a broken glass sound


Dear bob_bitt,
I am very sorry to say this but,looks like your TV is dead for ever.
Plasma TV's have a glass tube inside them that fires the pictures onto the screen. The tube in your TV must have reached its EoL (End of Life) and hence,would have shattered.(That should explain the shattering glass)
Before you throw out your TV though,try to get it checked by a professional technician. But if you bought your TV around 10 years ago,you will be better off buying a new TV.

There is not much you can do to fix your plasma. Since the plasma is less then 1 year old, still under Samsung warranty.
I would suggest to call them to fix it.
Good luck.

The popping noise you heard it's probably a capacitor blowing up in the power supply circuitry. If the TV is less than one year old, still covered under manufacturers warranty.
Let me know if you need any more assistant let me know.
