I'm repairing an IBM 5155 with defective power supply. I've try some
components replacement (electrolitc capacitors) with no results. The
rectified main voltage is present, but it never start up.
I hav ereverse-engineered this unit (there is no official schematic in
any of the manuals).
Anyone know if there are schematics of this power
supply available on the
net ?
Alas I have no scanner, so as yet there are no schematics in eelctronic
form. But I will see if something can be done.
Any experencies with this power supply ?
I've never had to repair one, but from what I remember it is a fairly
conventional design.
