Hey guys,
I didnt wq\anna resurrect an ol thread but this Sony's one I talked about before, just thought while im waiting for parts to come in i'd take another whack at it.
Well I can say the CRT's not the best, a bit on the pink side, I can tell this one's had some use. Well 20 minutes into it, (hooked up to cable) it went dead. Popped the circuit breaker in back of the set. So I turned off the power, reset it, popped it again immediatly. Well I checked the breaker to be weak, I have some in a bin and replaced it. It blew the 250v 5a fast acting fuse. THe slo-blo is still good.
So now imn thinking, hmm shorted filter cap. I did a quick ESR reading on the can and it tests in the limits, then I tested the other caps around the HV, all seem well in limits and no shorts. I did find a 6.5v 1000mfd cap on the vertical board at 1800mfd, so I replaced it. HOT and other various transistors and diodes test ok.
Any ideas what might be happening w/o a schematic?
Here's the old thread from Set of last year.
