Hi - I have a problem with my Amiga 1200 that appears to be caused by my ACA1221-lc. The machine has worked fine with the ACA1221 since early March which is when I purchased it. However, as of today, when I turn the machine on I get a black screen and the power LED flashes a number of times (no Guru message though). When I unplug the ACA the machine boots and operates fine. My A1200 was recapped about 4 years ago (no sign of leakage or fishy smells) and I'm using an Amiga PSU with it. I've cleaned the accelerator connector on the Amiga side with an eraser and then cleaned it up with IPA but this didn't help. I've also tried shifting the ACA back a little on the connector but again this hasn't helped. I run the accelerator at the 26MHz suggested so don't think its an issue caused by excessive heat build up. Any ideas please?
Thanks,
Neil.
