OBERHEIM SYNTH

I finally got my OB-8 out of storage and when I turn it on I get no sound.  After I replaced the battery, I tried loading the factory patches.  I could hear the audio file via the mono output, although the patch load failed.  That's the only time I heard anything.  I tried loading the patches again many times and heard no sound each time.  I would imagine these two problems are related.

This is my first attempt at electronic repair and would love to tackle this myself.  Any ideas what I could look at first?

Thanks, all!

I just had a great trade with someone that netted me a matrix 12 and an 8 voice ob-mx, both in just splendid condition. 

The ob-mx has a very nice interface, and really doesn't need an editor, except for the tuning tables…..it would be nice to have an editor for that. Does anyone know if anything exists? Sounddiver used to have very complete editors, but I don't have anything that will run it at this point even they had an ob-mx editor...
