A1200 Dead??

[Havana7]

Hi! After some years I want to return to Amiga computer, but I think that my A1200 is dead.

This is the problem:

  When I switch on my power supply (AT or ATX) my amiga do nothing, the screen get black and nothing more, sometimes it looks like the floppy tries to read. I touched the chips to see if they get hot and they do, are hot, the proccesor and AGA chipset are hot.

  So, I´m totally lost and I want to know if my amiga is really dead before buying another motherboard.

Thank you.

P.D.: Excuse my poor english but I´m spanish and my english is poor and forgotten.

Yes, I´ve tested other video signals.

About voltages... When I test the computer,I disconnect everything (except floppy), but I´ve tried with a Blizzard 1230 and a BlizzardPPC (with and without a Bvision), in the BPPC the fans runs correctly, but the results are the same.

Ammm, HDD should not be the problem, i left the computer in power on some minutes.

I think my amiga is really dead...

I think I would try to reset my MX Eprom if I know how to do it, could you explain it to me please?

Thank you very very very much.

Yes, I know it, I change Kickstart chips few years ago to install OS 3.5 and they were working perfectly.

But, if they can be reseted I would try it.

Thanks.

My power input is soldered directly to the mainboard, it has been working too many years, but i will try to use the floppy connector.
