Has my A3000 died?

How much voltage will the audio need? And why do u think the system wont start with the +12V?

 The audio circuit needs +12 and -12V to work.

 Reliable operation is in 10.5~12.1V range (symmetric to the negative line).

 Distortion in audio indicate bad audio decoupling capacitors. Namely C433 and C443 in big-box Amigas. 22uF x 16V. Prefer swap 'em for no-polarized version. Using regular, polarized versions is a project error in the Amiga boards!

 Also Paula can be involved in the audio problem, since she is the responsible for sound generation (among other things).

It got worse i was playing lemmings then i smellt something burning. It was one of the CIA's the one closest to the dauhterboard! I removed it and put anotherone in and same thing happened te CIA went boiling and i have them in the right way. It booted to a white/grey screen for a while now it
boots to a green screen. Now what could be the problem.

 BAD PSU!!! Check it before anything else!

 BTW: your CIA have gone south, a this time.

 Don`t trust on what you read from a multimeter with the PSU out of the board (no charge). Prefer to swap it for a newer unit, like an AT/ATX one converted (you need to swap the JP350 jumper position to use a PSU without the "tick" signal).
