I need to know how to fix the sound on a 48" Sony Rear Video Projector KP-48V45


Its most likely an issue with the audio out IC . Most parts have been discontinued for that model but if you send a email request for assistance to customerservice@tvrepairworld.com they will help and they should have the audio IC available for that model.

My sony kp-53v35 keeps immediately shutting itself off


Older model---it should when you try to turn it on have the red light blink for several seconds (set is checking things inside) and if comes on and shuts off that light should blink a specific sequence of blinks----5 blinks and repeat it endlessly---

I have a stupid question: when it first failed did you hear a small pop or smell a faint odor of something burning?

KP-57WS500 turning green or red and then off


Green and Red guns seems defective and requires replacement.
Both guns (CRTs) are no longer available so TV has no worth to repair.
