I am officially at my wit's end with two of my expansion boards and would like to have them looked at. I have a CyberStormPPC (060, 128MB) that worked fine a few years ago, but after being removed from one machine and installed into another it has never really been stable. At the moment, all I get is a black screen (my CV64/3D Scandoubler gives a sync signal and CapsLock works but the screen stays black, so I believe this means that there is a CPU problem). Tried two different 68060s, same outcome. Stripped my A4000 to a bare minimum, same outcome. The mobo was serviced a few years ago, so I have reason to believe that the problem is not in it.

Also, I have a Picasso IV that is flaky at best. Its scandoubler was broken when I got it, sent it to Amiga Center, came back fixed but did not really work for long.

I have no purposeful ways to test either of these boards, so I am looking for a (reliable) specialist who could take a look at them and possibly repair them. I am not in a hurry as I have several systems to play with, but would eventually like to get these boards working. Shipping is not an issue, but Europe would be preferred.
 
Hi,
From my experience the 060 socket needs to be re-soldered at first. I have done that several times already. Please PM me if you are interested.
 
Hello stachu100,

I've been searching around to find someone to do repairs. I'm curious if you still do repairs?

Once in a while my CSPPC will function, bother zer060 and PPC, and could be good until I power off the system. The fan I have on it is okay but could be better, and it's only been on the PPC heat sink. Keyboard's Cap Lock lights when pressed. UWSCSI going through the process. I bought one of those "Hard drive" CompactFlash devices from AmigaKit..so I'm able to see the SCSI check happening.

The Picasso 4 mostly produces a grey screen of 700x400 @ 75Hz (my TV shows this). If I power off, and slightly move the board's seating, sometimes I can get a 640x400 black screen and....maybe it'll display the Amiga native modes. If it gets to it, it'll display the High Res screens. Sometimes it'll start with a hazy / distorted Amiga screen. I could share more details if you like. But think covers it pretty well. From what you've read what is the likely possibility to fix both?

Appreciation.
