My keyboard amp's line output has stopped working completely.  there was no "warning" - no staticy sounds, no intermittent operation - one day it worked, the next day it did not.
 
I don't think I'm going to be able to find a schematic on it, it's an obsolete Roland KC-100 (they stopped making this model) and I've heard you can't get Roland schematics anyway. 
 
what's the chances it will be something easy to diagnose and repair if I open it up and try it myself?  any thoughts on where to look first?

Here  ya go.

hmm - well.  $5 to join for 7 days would get me the service manual.  might be worth it, IDK.

I've never been fond of those sites that make you pay for old manuals.  I'll have to think about it.

Man you're tight!

Here - maybe it's worth $3.00? Do ya squeak when ya walk?

Certainly in the D/FW area, you should be able to find a technician who could repair it.  I'm sure there is someone there of that level of experience who knows that stuff like the back of his hand and could probably repair it w/o the schematics. 

Have you tried turning it off then on again? 

google search turned up several sites that have it for free.

Reece Here...for only $2.00...just mail the two to me and download anytime. Two is low
as I go.

You did check the fuse and the wall outlet didn't you?

I'd open it and look at the line out jack and look to see if there is a burnt looking resistor near it but don't touch anything other than the jack with your hand. It is a good idea to keep one hand in your pocket when poking around in an amp. Anyway, maybe a wire came loose on the jack, especially if it is working otherwise.
Good luck and be careful.

I'd ditch BitBridge if I were you!
