A Missing Power Supply Voltage

A reading of only a few ohms may mean a shorted rectifier or two or a shorted Posistor. The HV may be developed from a single winding with many many turns of wire or a lower voltage winding and a diode-capacitor voltage multiplier. Focus voltage is derived from a subset of the high voltage winding on the flyback using a resistive voltage divider which includes the focus pot. In a nutshell the regulator is a switched mode circuit that uses a winding from the high voltage transformer to turn off the SCR.
