Checck within for visible signs of a capacitor burst in the invertor section or the convergence section or the driver.
If it is detectable then you can remove and replace with the correct rating.

42pc3d flat screen lost picture after a loud pop like gunshot, the fs2 fuse blown replaced it but no picture


The sound you heard was a capacitor popping. This is a common problem but is not particularly an end user repair. If you remove the rear case you should be able to see the exploded capacitor. If you are good at electronic soldering you may be able to remove the defective one and replace it. I'd take it to a service center though.

My plasma tv has just lost it's picture. I do have


There will be a fault in either the Y or Z sustain boards, these are responsible for driving the screen 9hence sound but no picture). The popping sound willhave either been a fuse blowing on the board or another possibility is one of the drive ICs on the buffer board has blown. If so it's best to replace the board.

No sound, no picture following a mini explosion in the rear


yes it can be repaired, the y-sus and z-sus boards are most likely bad. would require a qualified shop to repair it as there are adjustments to be made to the new boards.

Sound but no picture


you've lost your backlight, the inverter board are part of the panel, so hopefully u just los a couple caps on your power supply. You should check your powersupply for lifted caps.
