What is the output voltages for the power supply

a) basically it has to be acted upon by a supply voltage of at least 95V

to work.

b) of course, assuming the horizontal deflection oscillator works, same

with the horizontal drive and horizontal output transistor








it would generate output voltages on the secondary terminals

and 200V line will be active sending voltages to the

Video Drive circuits. Of course high voltage will be generated

ranging to at least 30 KV and there will be voltages on the G2 of the tube.


c) the easiest test point to look when it is oscillating, is the CRT heater

voltage, the heater lit when flyback is good ( mostly at night times when it

is dark ) and you can hear sounds, too.

here is a sample image

Green Arrow for the G2 voltage


d) having a B+ voltage reading of 75 V or lesser ( primary pins )

indicates a bad or partially shorted flyback, assuming your

horizontal output transistor and power supply are good & OK.

These only applies to CRT type TV's.
