> I have just bought a basic a-100 system, LC9 case, AD5 power adaptor, A-190-1 MIDI-CV converter, A110, A120, A140, A131. The problem is when I switch it on all the lights on the A-190-1 light up constantly and whatever I do nothing seems to happen, any ideas

Is the Adaptor on that rail, which supplies the A190
If yes:
Wrongly placed power multipin cables or/and wrong placed AD5 adaptor.


The basic advice is:
Install the modules one by one, power the system each time up, check
whether it works correctly, then power the system off and install the
next module.
If you install all modules in one step and then one of them causes a
fault in the supply rails (e.g by wrongly placed multipin connector)
then you do not have a chance to find out which module / which connector
causes the problem.
