Hi all;
In my other book with pictures,, it says possible causes for trouble..
Contrast control set too high, overloading the the amplifiers..
Video IF amplifier wongly aligned, with the video IF Carrier too low on the side of the response curve..
Faults in the Video Detector and / or Video Amplifier circuits.. Check coupling capacitors, decoupling capicators and bypass capicators for open circuits.. Check Plate Load resistors and grid resistors for incorrect values or shorting.. Amplifier grid biases may be insufficiently negative allowing grid current to flow..
Those with more experience, might be able to elaborate..
THANK YOU Marty
