Loss of X / Y gain on ProTrack CRT trace.
« on: April 27, 2018, 04:14:11 pm »
For sometime had an intermittent problem with the horizontal & vertical gain on my ProTrack CRT trace.
Sometimes just had a bright spot in the centre of the CRT.
Identified the problem as bad contact between the pins on the high voltage module, Part No.2A12-N4-T0B6Z1.
Removed the socket the pins go into and soldered the module directly onto the PSU board.
Problem solved.
As can be seen and previously described on this Forum I have replaced other components on this PSU to keep it going!
