OBERHEIM SYNTH

If you search for Linn 9000 schematic, you will find it quickly.I just downloaded it.   Unfortunately, the scan of the processor page is 
pretty bad.    That's where you would want to start if it's not coming up.If you have blocks on the display, it's not getting initialized, so the CPU 
is probably not running correctly.   Could be bit rot in the EPROMs,or a bad chip.   Or a power supply cap that's failed.   Lots of things.If you don't have a scope, I would say don't bother.

Thanks Denny,
Yeah I know they are around still. They will cost an arm and a leg though I'm sure. I am surprised I can't even find a service manual online (Forat has them for sale). I am ok with dealing with electronics and would like to give it a stab. Just seeing if there is anyone out there in the ether that knows anything about these. 
Sincerely,Rich Clarke
