Can see Mediator in A4000 but will not initialise after mobo repair

[JohnFante]

I have a A4000D in a tower with CSPPC, Mediator 4000Di MK2, Voodoo 5, SB128 and Ethernet etc.

I have just had my motherboard repaired. Batteryholder needed replacing and I had some sound issues.

I have confidence in the guy who repaired the board and he has assured me that the board was fine when he shipped it. However I have a strange problem that I think is related to the motherboard.

When I boot my machine it sees the Mediator in the early boot menu. But when I try to load an OS that uses the Mediator it resets with and error (OS3.9) or goes into a endless loop (OS4.1).

At first I thougt it was a software issue since when I boot from the OS3.9 emergency disc it boots fine and goes to AGA as it should. There I can also see the Mediator in the sysinfo.

However when I try to boot from the OS4.1 install floppy/disc (that normally autostarts my Mediator graphics card) it also goes to AGA after an guruerror. But also here I can see the Mediator in sysinfo.

I have tried both with my normal Voodoo 5 graphics card and a Radeon 9250.

I have also tried with my CVPPC graphics card. When I boot from the emergency disc it boots fine and I can use RTG but when I boot from a CVPPC partition that has Mediator software installed for my SP128 and network card it resets endlessly.

It can of course be the Mediator that has stopped working but I must admit that I doubt it since it worked fine before and it is only a little under a year.

Any suggestions/advice?

I have tried resetting the Mediator (several times) since I have had that problem previously. It is not that this time.

Below you can find a link to a sysinfo screenshot. As far as I know that is the correct numbers for a CSPPC with a Mediator.

As mentioned before I think the problem is related to the repairs that has been made on the motherboard. My keyboard (original A4000D keyboard) does not work after the repair. I get different error codes. Two blinks, three blinks and solid light. But no reaction. Just dead.

Tomorrow I will remove the Mediator and put in my old Zorro bridgecard and see if that cures things.

Thank you for all your suggestions.

Well I think it is the Mediator that is acting up.

I replaced it with my old zorro bridgecard and now everything works fine.

Any suggestions on how to fix a Mediator? :-)

I do not think it is done with a cleaning etc. since it is only a year old. I think something is broken. But I could be wrong :-(

[JohnFante]

Ok. I will try that.

I have a new problem however :-)

The sound volume is very, very low. I have to turn my speakers up to max to get just a little sound. The quality is ok just very low.

Sound was one of the things I had fixed and it worked fine yesterday. Maybe I have destroyed a soldering or something when I was fiddeling around with the Mediator.

It is not a PSU problem. I use a high quality PC PSU.

Any suggestions? As far as I remember low sound is normally a problem with one or two of the capacitors near the sound output.
