Question
I have an Amiga 1200 that wont boot from cold unless you short out the +12v power pin to ground. Then it will hard/soft reboot all day long.

I have replaced all the caps, 2 were faulty, but the problem persists.

Answer
Hi Arnie,

I wish I could give you an answer as to why your A1200 is hard/soft booting, but unfortunately, I'm not savvy with that level of computer electronics. As you've already surmised though, it does sound like a very low-level hardware issue on the PCB or its components.

I would suggest asking your question via the old Usenet newsgroups (now owned by Google):

http://groups.google.com/group/comp.sys.amiga.misc/topics:

http://groups.google.com/group/comp.sys.amiga.hardware/topics:

Someone there should be able to provide some electronic-level assistance or at least give you some ideas to try. I'm sorry I can't be of more help on this, but I trust the newsgroups will turn up some answers for you.

Sincerely,

Greg
