anything at all go to a landfill that can be repaired. And besides
the ecological aspect, it is so much more rewarding to fix something
that is considered dead by most people. By the way, the part (1
piece) from Mouser was $1.39, and although I'm sure that the shipping
and handling will increase that figure, it still should be much less
than a replacement supply.


I agree, but unfortunately more and more often now I am finding that it
simply is too hard (time consuming and frustrating) to repair some of
today's electronics.

One of my Enermax high-end switching PC power supplies crapped out last
week and while I quickly found the problem (a shorted Mosfet switching
transistor and a couple of associated passive components) it was simply
impractical to repair the supply without hours and hours of labor. The
Mosfet was riveted to a heat sink that was in turn buried under several
layers of other components. Removing all the layers would have taken a
lot of time and extensive desoldering. While I would have preferred to
save the supply I decided instead to replace it at a cost of $90. But
now I've got some nice quiet 8mm and 9mm fans that I can use elsewhere.

OTOH I recently repaired a 10 year old 27" Sony TV that had a failed
power supply IC - it was easy to get to and while I was at it I improved
the heat sink so it won't likely fail again. So you win some and you
lose some.

I hope you win the PS battle and that it only costs you $1.39 plus S&H.
Post back and let us know if you succeed.
