Alvin,
Did you resolder the coil between the base of the H.O.T. and the horiz.
driver transformer? Common problem in the CTC203's.
Here's a couple more tips I have written down---TV tries to start, after
pushing power button several times TV comes on with no horiz. deflection,
found poor solder connection on C14403 in yoke circuit.
Dead, clicks at turn on----unit going into x-ray shutdown, replace
Q14901(#147665) transistor, checks leakage.
