AW: [Doepfer_a100] A-190 issues: no gate output, solid LEDs on power up

2013-08-20 by yahoo@doepfer.de

> Hello,
>
> I just purchased a used Doepfer A-190 Midi/CV module and I'm
> having some problems with it.   Hoping for a DIY solution.
>
> Connected it to my TipTop uzeus flying bus board.
> Super triple checked polarity of the module as well as the five
> other modules in my case.  uzeus is properly showing -12, +12 and
> 5v power.
>
> First problem.
> Gate LED not blinking.  Measured with multimeter.  No voltage.
> Clock, Reset, CV1, all working great LEDS light up and multimeter
> shows voltage.
> So I disconnect everything but the A-190. Power on, problem still occurs.
>
> Second Problem.
> Attempt to hard reset to factory settings.
> Now, when I power on, the clock LED is solid ( flashing a
> little).  The 5 Config/Performance LEDs are solid on.  no
> blinking.  And the LEDs just stay on.
>
> Any ideas what could be going wrong?  is it dead? Are there some
> components that are potential culprits that could be swapped out?
>
> There person I bought it from assures me that it was working 100%
> before he sold it :( .

> Thanks in advance!

From the distance it's impossible to make a diagnosis. The module has to be
sent in the module for check/repair.
