Michael, the model you have is the one made by Tatung.The model that had the
2.2Meg ohm resistor was the one with the serial number starting with
DKxxxxxxxx.
The most common fault for yours, with no power was a rectifier diode in the
secondary of the power supply going S/C.Check D803 in the secondary side of
the power supply for S/C.Also this model had a common fault for the pins on
the flyback transformer to go dry jointed.Check for dry joints as well.
Hope this info helps and let me know how you go.
Cheers
Joe
