Doepfer

just now, the end of a patch cable came into contact with the circuit
board of the doepfer 190-2 midi to cv.  now the a-190-2 no longer
seems to work properly.  the gate LED is always on, and the pitch CV
doesn't put out anything.

there are a couple socketed chips on here, but does anyone know about
servicing this module?   would it be worth trying to swap out the
chips?

I'm not sure where the cord touched the pcb.

thx

giorgio

hello giorgio,

sadly i don't have an a190-2 and i also don't have the
service manual for it, so i cannot help.
the whole doepfer crew is on holidays right now,
but they should be back next monday.
i believe that christian assall is the right person
to talk to in this regard, maybe you should contact
him directly. his email address is software@doepfer.de

best wishes and good luck

ingo

From the distance it's difficult to make a diagnosis. Probably the
microcontroller is defective and has to be replaced (but that's only a
guess). It is available as a spare part from the representative in your
country. To be on the safe side I'd recommend to return the module for
repair as you need a special tool to remove the microcontroller from the
socket.
