WCP Repair a switching power supply
WCP Preface:
WCP While this repair story is about a fifteen year old
WCP VCR, the proceedure is one to follow for everything
WCP from PC power supplies to Audio CD to DVD players.
What a nice happy ending! While this is not supposed to be a Pekinpah
movie script, it didn't have our hero riding off into the sunset. :-(
Only on the usenet! :-)
Thanks!

... Over a hundred billion electrons were used in crafting this tagline.
Only trouble is, it doesn't always work out that way. We had one, similar
setup, mimimal heatsinking, etc. and a blown fuse and shorted transistor.
Replacing the fuse and transistor resulted in both blowing again. I then
heard about an outfit ("Studio Somthingorother", ask me if you want me to
look it up) that offered a "rebuild kit" for this and a lot of other models
of VCRs. For less than $20 delivered, I got this kit that contained new
caps, diodes, resistors, and a bunch of other parts. It was rather tedious
to go through replacing all of that, but I'm glad I did as that VCR worked
right off when I plugged it in and is still working fine, 5+ years later.
