maybe a bit off topic, but haven't found any other newsgroup to post this
I own a 7025-F40 of which recently the power supply broke down.
When I attach the power cord it makes a funny, very high pitched noise (like
sparks leaking in a transformer), the blower won't start and (obviously)
nothing works anymore.
If I press and hold down the test button, after a while the green led comes
on and the blower starts turning. When I release the test button, the blower
stops again and the green led comes off again.
Anyone out there that has had similar experiences ?
Is there anything I can do myself (I am a radio amateur, so I do know a bit
of electronics...) ?
The service manual of the F40 states that power supplies are non-servicable
and should be replaced as a unit.
If this is necessary, can anyone tell me where I would have the best shot at
obtaining such a power supply (preferrably in the Netherlands of course) ?
The power supply data:
Model : AA19710
IBM P/N : 07L7475
EC NO : E77716
FRU NO : 07L7476
