Is this repair project worthwhile, given the circumstances?
Sony VCR, model SLV690HF, died suddenly. It worked fine up until
I pushed the power switch and eject button on the front panel almost
simultaneously (I don't use any VCR much; it's my wife's
preoccupation). Now it's absolutely dead. I suspect the power
supply, perhaps a semiconductor therein, given the symptoms.
The fuse is okay, and I see that there's one 'o them newfangled
switching power supplies. My electronics hobbyist years ended
before they became prevalent, so I don't know a thing about them.
There's a lot in this newsgroup about related issues. One posting
alerted me to one other circumstance that might be relevant: It
mentioned that the power supply runs hot. In the last year, it's
been powered on more than off because I rearranged the connections
such that it has to be on whenever TV is being watched.
The notion of a power supply rebuild kit looks attractive, and I found
my way to the Web site of Studio Sound Electronics. For less than $20 for
the kit and two or three hours work, it would seem worth it to do
the repair. The VCR worked fine for eight years, and cost $270 new.
Assuming that it is the power supply, I guess I need to know two
probabilities to decide if it's worth it to order the kit and get
to work:
1. That the failed component is a semiconductor (to reduce
the number of parts I'd have to remove and replace).
2. That the rebuild kit will include a replacement for it.
