Hello,

I recently purchased an A-190 second hand from someone who assured me
the module was working fine.

When I plug it in and turn the system on, all the LEDs on the left as
well as the reset and gate LEDs turn on, and stay on. Sending midi to
the  input doesn't change any of the LEDs status. pushing the buttons
doesn't change anything.
 I've got the low cost 5V adapter installed, and I can see on the bus
board 5v power is present. I'm sure the ribbon cable is installed
correctly.

Any ideas? I've tried both the system reset procedures in the manual,
they both do nothing.

Cheers 
Tim
