Our campus has recently purchased a good number of AT&T PC6300's. All of them
work great, except one. When you turn the system on, the fan starts running,
but the self-diagnostics don't execute, and the monitor has no display at all.
Those cute little flashing red lights on the keyboard don't flash either.
If you know what may be causing this, please let me know.
Leave messages in the NET.MICRO.ATT newsgroup
or BITNET: O05 at PSUVM
Thanks in advance,

It turned out he did not have his dip-switches set correctly. Check in particular the video monitor settings. I have heard some bad stories about AT&T changing the dip switch usages between rev.s of the motherboard so you might want to keep that in mind.

A bad keyboard will cause this. Try swapping keyboards with one of your other 6300's. Harvey S. Cohen, AT&T-IS Lincroft, NJ, mtuxo!hsc

On my 6300 it was (is) doing the same thing. The trouble i found is the power supply is putting out +2.263 volts. I am waiting for a new one $ 174.00 (ouch). Jim Spring

Probably power supply. It sounds like you have AC for the fan but no DC out
for everything else (including green monitor). The power supplies are
notoriously unreliable (until you find that one special one that seems to
just keep working and working. Check your DC coming out of the front of the
power supply. The voltages are engraved just above the connectors.
