What the heck do you think why I'm asking here for some documentation?
Repairing that Drive is a matter of time, unlike my comercial work, where I
got pay'd for my time I have to do this in my free time, its hobbyism.
The contruction of this PSU is ugly, you can't power it on if it is
disassembled, since there 2 PCBs with to short wires between in there.
Next thing is, the schematics aren't that straight forward in that thing.
It is over one year since I last looked at this drive, only the mail from
shaddoo brought me back to this thing.
Yes, I'm always testing electrolytics with an ESR meter any time I work on
PSUs. You are satisfied now?

Christian, I've repairing Switching PSUs and
Drive Controllers for the
Industry to get my daily income.
It seems, that I have todo some reverse engeneering on the PSU of the TSZ07
to find out what's wrong. It isn't the main switching part of the PSU that
So if you are commercially repairing PSUs, then I assume that you have
already traced the schematic of that area, and that you know what the
power resistor is good for.
Still, you haven't said if you have checked the electrolytics in the
standby circuit.
