[sdiy] Andromeda A6 repair?

Apparently the supply of main boards has dried up.
Could be a chip or supply on the board.  Don't know yet as I haven't opened it up yet.
I think fixing an A6 is a DIY effort as Alesis changed hands (I didn't check on the possibility though). To keep costs down I want to give it my best effort before buying a board for big bucks.  That would make it smarter to just buy a working unit to begin with.
Just about every synth I have was originally a dead or dying unit that I fixed.
Just another one of my sicknesses.  
I'm not too worried with this one.  Someone will always buy it from me for what I paid if I give up on it.  If I get it working though it's a keeper.
I know what you mean about firmware though.  We deal with this on products in development at work.  You would need a custom loader and the file - and this all is not public - or you would need a working unit to remove the part and copy it.  For synth repair maybe some kind soul makes a file copy of it for posterity.

Last time I got "freezes at boot up splash screen" synth for repair, it 
ended up in Clavia itself. Corrupted firmware.
If Alesis can make/sell replacement mainboard, I'd go for it no matter 
the cost, and not even try to fix.
