i GOT THIS 60" SONY FOR FREE IN HOPE TO REPAIR. The only info I got on it was that it got error code 4. when I

pluged it in I indeed got the code 4 repeating over and over. but then I smelled something and then seen smoke.

upon feather investigation I seen capacitor C521 burned out. I'm not sure if this happened before I got it or not.

but I pluged it in again and did not get smoke this time.

when I first pluged it in I heard the tv turn and and can fill static on my hair. and then the smoke. after that no

tv electric static. but still getting the 4 code. What should I look for or should I replace? I have a multimeter

to test if need be.

Thanks,
Brian

Where is your head/hair/toupee? Near HV splitter, flyback, CRT anode wire?

How sure are you on capacitor's location number?

Anyway "found on web:"
Q502 horizontal output transistor shorted C517 burned & shorted.

&

Found C512 (102@2KV) shorted across Collector/Emitter of Q502.

Can you post a picture from opposite angle from the metal heat sink. Is transistor on that Q502?
