Have TV Questions? Ask a TV Technician
Hello, Sorry you're having problems. No indication of power at all on the set indicates that the power supply board has shorted and failed and requires replacement.
The pop is either an IC regulator shorting, a ceramic fuse blowing (due to a short elsewhere on the board) or a capacitor exploding. In either case this requires replacement of the power supply board within the TV to fix the issue. There are no pushbutton fixes or settings that will correct this. If you would like to see about a DIY repair (swapping out the board yourself) then I will need the full model number off of the back of the TV to attempt to look up that part for you.
Alternatively, if this is not something that you're comfortable with, then a shop will typically charge $250-$275 parts and labor to swap out the power supply board in a 52" (they don't make a 51") Plasma, or LED set and one can be located using the link below:
Again, if you're looking to repair the set yourself, then simply postback on this page with the model number found on the sticker on the back of the TV at ANY time and I can search for that part for you.
Other than that, I'm sorry for the bad news here and wish there were a quick fix.
