Perry Bower - Electric Medic
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.
