A1200 Power Tower switch on & reset issue

[utri007]

There is power - any connected drives will spin up.  The display from the native video output is black but there is a video signal.

Is it so that you A1200 is powered through mediator? Have you really tested it without mediator? I had same problem, it was my Zorro bushboard. One cure was connect floppy power connector from PSU to morherboard. Then I got A1200 mobo's power connector remowed and cables soldered to it. Cables was connected to PSU. That way my A1200 get power two ways from PSU. Seems that powering through bushboard has some problems.

Hi, yes I have tried with and without the Mediator.  I've even had all the hardware setup outside of the tower and it works fine!!  It's only when the motherboard is fixed into the tower that I have this issue.  Very strange :confused:

OK, I think that you have a same power problem that I had. Connect PSU's floppy power cable to mobo's floppy connector so that mobo get little more juice. If that solves your problems, then mediator doesn't have good enough contact to mobo. Very common problem. I would suggest that you desolder mobo's original power connector and solder cables to it and connect them to PSU. Not stupid move any way.

I could easily understand, that mediator is little bit different position than it is in tower, thats why it worked without tower.
