I have this analyzer, power supply boards are ok, after power up, diodes DS401, DS403, DS404, DS405, DS406 and DS407 are constantly on. What can be wrong with this board? What points should I check?
In the service manual, there is a troubleshooting sequence to follow based on the light activity.
I have changed the CPU board and now the analyzer is working:) But unfortunatelly I have acquired CPU board with 011 option and I don't know how to remove it because my analyzer is without 011 option.
In the service manual, you can download online, there is a way you can turn the option 011 off from the front panel.
