If The Set Has The Gemstar With The Two Flat Ribbon Cables, Then It Is
Probably Bad. Very Common Problem. We Have Several Different Versions Of
Gemstar For Test, That Is The First Thing We Sub On The Ctc203 Chassis
For Dead Set. 
If That Is Not It, Unsolder The Collector Of The H.O.T., Then If Set
Starts Up With Sound, Then The Flyback Is Bad. These Two Fixes Probably
Represent 80% Of All Failures, (Non-Lightning, And Power Supply
Problems), That We See In Our Service Center. 
There Is A Coil Between The Secondary Of The Horizontal Drive
Transformer And The Base Of The H.O.T. That Usually Causes Intermittent
Operation. The Set Normally Will Have Sound When 
That Connection Is Bad.

Subject: [TechAssist] CTC203 won't start and click 
3 times 

This set, when you push power try to start, but it won't, then makes 3
clicks on the degauss rely. The B+ current to the fly rise to 1.5 amps
then B+ voltage drop to 20V and start clicking. Replaced fly back,yoke,
HOT,ringing caps and diodes, 
and pin amp transistor with no results. 
=A0=A0=A0=A0Any help please will be very appreciated, Thanks in advance.
