Emax

I recently purchased a lovely EmaxII 8mb Rackmount unit whose only 
problem seems to have been a blown fuse, for $50...once I replaced 
the fuse (for the power switch: 250, 2a) everything works fine 
EXCEPT: 
1)it has an internal SCSI Quantum ProDrive Els (40mb i believe) and 
everytime i plug into the external SCSI, the Emax recognizes 
neither...I even tried changing the SCSI boot id and it recognized 
both until i tried loading a bank, when it proceeded to cop out with 
the SCSI Hardware error...also, it recognizes the external with no 
problems if the internal is disconnected...

Problem 2) the lcd display, probably due to my muckin' around with 
the guts lost it's light, except for when i press on it...the lcd 
thing is a common problem I hear...also could be a victim of the 
original power surge which blew the fuse....

As a solution to the Lcd problem, and as a precaution against further 
power supply problems, I swapped guts with my emax2 keyboard, that 
is, I put the whole shebang from the rackmount:drives, output 
board...everthing except the power supply and whatever else I can't 
remember...so I now have the same scsi problem, which I don't really 
care about anyway, except as one of those things that should work but 
doesn't...and the lcd problem is fixed BUT: the realtime wheels don't 
affect the samples no matter what I do...control enable is fine etc 
etc...
   Now what I'm thinking is that either I can solve this problem 
(someone can walk me through replacing the lcd and verifying the 
integrity of the rack's power supply) or I can just put the 8mb rack 
guts into my 2mb rack (or was it 4?)and let you folks fight it out 
over whats left over: a 2(or4)mb rack synth with lcd and possible 
power supply problems, and a keyboard version (1mb) with a fried 
output board, one broken key, one fried key (samples won't go to it), 
and minus a fuse or two..

Please respond with qyestions and suggestions...if you're going to 
ask me if i considered obvious sources of the technical difficulties 
(besides my own bungling ie: fried 1mb output board)then please 
follow up with something less obvious...try to stick to layman's 
terms but don't shy away from using chip names, etc. as long as you 
can tell me where to look. Hah , sorry about the fine print... i'll 
take what I can get ;)
