What does pin 22 (horizontal out) of the T-chip measure? It should be 3
volts. I had one where there was solder splash on R14322 which caused a
partial short to ground and pin 22 only measured 0.2 volts.

CTC203AD9 chassis. Did the coil on base etc. I mean, I really checked
it
well. Removed coil, stripped back some of the enamel to make a larger
land
for the solder to grab. Removed a re-installed driver xformer. Set will
come
on with no HV. Drive is not getting to Q14301 driver xistor. Resoldered
surface mount Q14302 and surrounding parts. Seems to be in this area
though.
I put my meter on Q14302 and set came on.
HELP !
