Hi,
I traced the 18Khz signal all the way from the moment it enters the
logic board until the video board (attached to the neck of the CRT).
The signal is there (it has different shapes but it is 18KHz). The
No, that is a different 18kHz signal. That is the video, which will
have a significant component at the horizontal frequency. It
starts from pins 6 (intensity) and 7 (video) of the DE9 connector
You need to trace on from pin 8 to transistors on the main board,
right up to the flyback transformer.
