I have the service manual for the Pioneer PDP-502MX, and mentioned within is something called the "Technical Manual".
In the Service Manual, under Adjustment, it describes how you can place the display in Factory Service Mode (and instructions as to what you can do in that mode), or Integrator Mode (which refers you to the Technical Manual for instructions).
What is the Integrator Mode? And what's in the Technical Manual (besides instructions for Integrator Mode)?
Thanks,
