The device had no video. Measuring the 800V tap showed only 85V present.
Voltages
+6V is 6.028v, fine
+12v is 12.2v, fine
+28v is 23.4 volt
+32V is 26v
-40v is -32v
Vertical amplifier
tp2 showed:
16.7ms should be 17ms, assuming it to be ok
Voltages seem OK too.
TP3 (inverse of the above, more or less)
TP1 should be a clean sawtooth but looks like this:
Horizontal
tp5 (5V square 64us):
Q14 base:
Must be between -0.5 and about 1.5V, 64us (dead on)
Q14 collector:
Does not look right.
Collector T13 (driving transistor for the flyback transformer):
