| 2823.1 | knee jerk reaction:power supply | SAUTER::SAUTER | John Sauter | Thu Aug 10 1989 16:59 | 3 |
| I'm not a hardware guru, but it sure sounds like a fried power supply
to me.

| 2823.2 | Maybe a shorted backplane.. | PUERTO::ALVAREZ | Back in Puerto Rico | Thu Aug 10 1989 19:45 | 12 |
| I'm no power supply expert, and I don't know anything about
the A2000 pwr supply, but my guess would be a short at the output
of the power supply.
Some power supplies incorporate circuits that will shutdown
the power supply if it detects currents above a certain limit on
its output.
So maybe, just maybe, something is shorting out your A2000
backplane. If my assumption is correct your power supply should
work if you can remove the short.

This problem sounds exactly like a problem I saw on another
B2000. The fix was a new power supply.

| 2823.4 | Check the cord | TLE::RMEYERS | Randy Meyers | Thu Aug 10 1989 22:02 | 6 |
| But don't overlook the obvious. Make sure the power cord is plugged
into the wall and into the computer. Once my 2000 wouldn't power up
because the power cord was working itself loose from the connector
on the back of the Amiga.
Good Luck.

| 2823.5 | Thanks | MDKCSW::DAVIS | That's not a BUG, it's a FEATURE! | Fri Aug 11 1989 06:20 | 10 |
| Thanks all. I called a local repair center and they told me it would
be two weeks before they could even look at it! OUCH! It does sound
like some sort of overload that is causing the power supply to shutdown,
but I'm just a software weenie so what do I know.
I poked around inside the box and didn't see much so I guess I get to
wait for a month or so to get it working again. What fun...

| 2823.6 | Sounds like overload, try w/o fan | FRAMBO::BALZER | Christian Balzer DTN:785-1029 | Fri Aug 11 1989 07:28 | 11 |
| Re: *
Note that I'm basically a software weenie, too. But I've diged into
hardware quite often. I go for the overload/short circuit theory,
too.
Since the turbine, erh, fan won't start generating noise ;-) ,
I'd say that you disconnect it and try without it...

| 2823.7 | Burned out fan?? | LEDS::ACCIARDI | | Fri Aug 11 1989 10:42 | 10 |

The power supply on my 2000 won't come up if the fan is disconnected.
I found this out whislt swapping in a less noisy fan that I picked up
at Radio Shack. In fact, if your fan were burned out, it might cause
the problem you describe.
I'd try replacing the fan with a comparable Radio Shack unit. If it
doesn't work, you can always get your money back.

| If that doesn't work, try removing all removable things from the system
(modules, disk drives, monitor etc.) to see if you can get the supply
to come up and stay up (fan keeps spinning). If it does, replace things
one by one till it dies again. When it does, you've found the faulty
module.

| 2823.9 | Yeah! | LOWLIF::DAVIS | That's not a BUG, it's a FEATURE! | Sun Aug 13 1989 05:54 | 6 |
| Thanks again everyone, my Amiga lives again!!!!! It _WAS_ the fan. I went
straight to Radio Shack and got a replacement and I'm back in business!
Yes, I'm definitely a happy camper...

My 2000 came with the fan wire broken. It had been caught under
the cover of the power supply. The computer worked (although it
got rather hot.) I fixed the wire and now live with its Pratt &
Whitney whine.
