estudio 353 help with no power, but fans running ?

[CCS]

Before I dig way into this 353... I have not had one of these series machines with problem of no power but yet you can hear a couple of cooling fans running, what am I looking for here ? Is it really a power supply failure?

I cannot access 08 or any other codes...

And yes I have all the service manuals, thanks

Appreciate any input, thankyou

Check all the voltages and fuses on the power supply. If any are blown trace the circuit and order a new power supply. If you replace the fuse it will only blow again.

you maybe looknig at a shorted circuit, try turnning off the unit remove all connectors from the logic board except for the power supply turn on the unit there should be a display on the screen (if no display check power supply), then reconnect the connectors one at a time if the display turns off you have found your shorted circuit.

OK, so I've swapped power supply and no luck, still have a dead machine, only fans run.
I swapped HDD - no luck.
I swapped oper. panel - no luck.
I re-seated all board connections and tried powering on 1 at a time - no luck.

Any other ideas ?

Sounds to me like a dead e-Bridge board.

You started off on the right track and replaced the power supply, so the next thing I would replace is the e-Bridge board.

Yes, my thoughts too, but unfortunately my parts machine that I'm using to rob parts, the other boards are gone.
Guess I'm out of luck...

As niorelle suggests, a pinched wire - in most instances we have found (in 350 & 352 mcs) a hasty installation of a Fax Unit can pinch & wear the coating off the Black wires behind the fax unit causing a short.
