A3000 Failure

[jlariv8957]

Hi,

I've buyed a buster 11 chip for my a3000 with a fastlane z3 & picasso 2+/A3640 card

All was running fine for about 3-4 hours then some garbadge graphics on screen appeared.i turned the amiga off & on then ... black screen. after removing all cards & verifying all chips no heartbeat.
When I remove daughterboard the screen becomes yellow (this is normal, i know it was just for testing purpose)

I also heard some noise : FDD's head where moving randomly

I let the 3000 on about 20minutes and the 68030 was anormaly hot: i burnt one finger in about 1/2 second !!

If someone have an idea about this or how to find a new A3000 motherboard please let me know !

Thanks.

Hi,

Thanks for all your advices,

I tryed to replace buster with the older one. for the other custom chip i have some spares but not at home, so i don't tryed to replace the other chips.

why all the other chips would be dead ?

I have also thought to DMAC because it is the chip whitch is overheating with the A3640 but i don't have spare for this chip.

Thanks a lot.

My 3000 is living !!

I replaced Paula from my old stock and the 3000 runs fine now, i have some luck the first chip i replaced was the deffective !

The hot temperature problem was because i remove my A3640 from my computer without correctly changing switches on motherboard.

All is ok now
