Hi,
....Repairing a
switching power supply is one the last
things I would want to do.
Why?
Personally I've never had any luck repairing switch mode PSUs
either....obviously there's some hole in my understanding of them....
Actually, I have managed to repair a couple; but that was when I did a City
& Guilds course in electronic repair at college (I was bored....) and had a
full schematic and circuit description to work with.
But going in blind? <shudder>
TTFN - Pete.
