Need help with dead CSMKIII

[amesie2]

I just bought a used CSMKIII and it is dead! I need to get it repaired and am wondering if there is someone who can repair this for me?

I have tried replacing the CPU with a known good one and also the Crystal. The memory too has been swapped out, I am thinking that someone tried to flash the firmware updates and something went wrong. The other thought is that there could be a loose solder joint along the CPU slot.

The screen does flash when first turned on then turns to a dark Gray which stays solid with no action.
I have the CSMKIII mounted in a 4000D rev b motherboard, Buster 11, 3.0 roms, 6.3GB hard drive and HD floppy drive.

Any help would be appreciated!! :-D

I'm not sure if it does require 3.1 roms or not, I suppose it might make sense that it would tho.

@alexh

Thanx for the info didn't realize AC repaired them, is there anyone in the states that might be able to repair this?

@lumby

Thanx for the insight I did try plugging the board into another 4000 that does have 3.1 roms and still no go.

@pulsatingquasar

Yes, The jumpers are in the correct location I checked them several times.

@lemmink

I guess I should send it off and have the socket checked along with the rest of the board. I would think that even if it did cost 200.00 USD to repair it would be worth it since I didn't pay alot when I bought it.

Thanx for the help guys!

I did try the caps lock and it does stay off after about 8 hits or so which is probably a good indication that the CPU isn't functioning.

@amiga92570

I think I will ship it off for repair it probably is the CPU socket as indicated by someone earlier. I did get the board cheap enough that it definately is worth repairing. How is the turnaround time from Amiga Center?

Thanx
