OBERHEIM SYNTH

Hi Tim, 

 

Tricky one as so much has stopped. But lets go thru a few basic things 1st

 

1st and foremost check yr getting all the voltages off the PSU and also to
the voice board. The connectors are prone to oxidisation so this could
explain the sudden death. Also when u play the keys, can u see the LEDs on
the voice boards flashing.  This will provide quite a clue as if they flash
a lot of the digital stuff is working. Also check the tape switch on the
back hasn't been accidentally moved. 

 

Let me know if I can help more, I fixed one that was in a similar state.
Took a while but got there in the end.

 

Regards

 

Ian

Subject: [oberheim] Problem with OB-Xa - no sound

 

  

Hi all,

I had a perfectly functional OB-Xa which I turned on today and now I get no
sound. After turning it on the Patch 1 light blinks several times (like a
bad voice in auto-tune would blink) and then nothing happens.

LEDs are lit on the board, but pushing buttons does not do anything, meaning
none of the functions work, pressing any buttons won't make them light,
etc..). No sound comes from the outputs.

Any ideas?

Thanks in advance,

Tim
