> Hello,

> I just purchased a used Doepfer A-190 Midi/CV module and I'm

> Connected it to my TipTop uzeus flying bus board.
> Super triple checked polarity of the module as well as the five

> 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

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