I heard a loud pop and the display went out completely. i can still here sound but the picture just isnt there

A popping sound as you describe sounds as if your tv blew a couple capicators on the main control board. More than likely , you are needing to aquire a new main circuit board.

There is a power supply failure and this might need attention of a qualified service technician

Bulb may have popped. Cheapest fix, unless your an electrician it the only thing to really try before replacing set.

The snap/pop was your lamp exploding. Your users manual will give you the part# and instructions on installing it yourself.

Ur Main Tuner signal board is dead.Replaced the Main Tuner signal board will solved ur picture problems.

sounds like a large capacitor has gone on main board
check for swelling or bulge/can be square blue in colour

Ur tv have burns capacitors,look for pop ups caps.

That loud pop is your Y and Z sustainer. Normally it goes out completly but yours is still half working. Not usally fixable yourself, because you may need to flash the control board f/w , which is proprietary and can't be aquired unless you work for them,

Does anything come on the screen? Input display box? 
If no:
Sounds like it could be a blow capacitor. Cheap part, but need someone with a little electronic know how repair to fix it.

Bad IHVT ( flyback transformer)--need complete service
number off back for part #-----------Let me know...T.
