Has my A3000 died?

[Gwion]

I opened my A3K today to replace its HD. I took the LEDs off to re-solder them.
I put the put the LEDs on when the machine was on then the connections of the HD led hit the metal case of the machine and it sparked then the machine went off.
The PSU powers when not connected to the mobo but when its plugged into the mobo it doesnt power.

[Gwion]

Oh i'll leave it for a hour then i'll check of disconnecting the HD/Power LEDs will fix it.

[Gwion]

Got bored of waiting for a hour so i tried the PSU on the mobo abit loose and the A3K boots.
But when i put it on fully it doesnt  :-?
Any ideas?

[Gwion]

Ok will do

[Gwion]

Took out the motherboard no cold joints.
Connected my A2000's PSU to the motherboard and still the same.
Dont know what else to do.

Accident  :-(

[Gwion]

I replaced the PSU and guess what?!?!?
It doesnt work!!! :madashell:  :madashell:

[Gwion]

only Joking it fixed it  :-D

[Gwion]

Oh it kinda works its just the floppy driv the doesnt even when a external one is connected. The LED on the floppy drive is constantly on.
Any ideas on how to fix it?

[Gwion]

So if i replace them it should work? Will ones from a A500/+ work?

[Gwion]

Sounds like the floppy cable might be in upside-down or something. Double-check, or try with another cable?

Yep i've tried that but still the same and the external drive should work even if that happened

[Gwion]

Oh i just remmembered when i plug the +12V into the amiga 3000's mobo it doesnt power, Any reason why this might be happening? I think its might controller the disk drive stuff?

[Gwion]

SO what can i do to fix the audio?

[Gwion]

I replaced the CIA's and now the floppy drive works!
But i did 'kill' one CIA by trying the +12V when i got the floppy drive working. The the floppy drive didnt work again untill i replaced the CIA (one nearest to the back of the machine)

Ok audio kinda works its just sound quiet andis low quality when at a reason able volume
