RCA just stopped working. I checked the fuse and it was burnt. replaced the fuse and still does nothing. what else could it be?

It sounds likely that you have a power supply fault.
Check the Switching transistor and replace as required along with the tuning capacitors and any failed diodes.
Hope that helps.

Have sound, no picture

Check to see if the Lamp has shattered. it is accessible from the rear of the set. Be cautious when you remove the Lamp Assembly for pieces of glass that has fallen out of the Lamp Assembly.

The loud pop was a capacitor blowing up or the high voltage transformer blew up. Very common problem.. if its the Transformer be expected to pay 250 or more to have repaired.
