on GA18 atlas copco compressor we get an error code 104


we have gone thru all steps listed in manual to correct this code with no help, the only thing I find is to turn power off and check for power at all connections to the monitor and surprisingly enough with the power off I get no reading on any of the connections, now what?

It's a VSD, isn't it?

If so, same as here:

If not, let us know.
