Question about Sony FD Trinitron WEGA KV-36FS120 36" TV
The snap you hear is likely from the high voltage in the set. The worst case scenario is that the picture tube (CRT) is shorted and is arcing internally causing the set to shut down. There are other less expensive possibilities such as the flyback transformer which can also fail in such a way as to arc. You may be able to see through the top ventilation slots in back as you power the set. The neck of the tube extends back into the rear cabinet and you could possibly see a flash inside the tube neck if it is arcing. I would have to recommend you have a technician check this problem to diagnose it. The tube, if it is defective and out of warranty, would exceed the cost of replacing the TV. Check your warranty as the tube generally has a two year warranty and other parts one year with 90 days on labor.
