i dont know if your problem is the same, but i will to check the flyback; althought when i set the control screen to full, i can see the screen in red color whit retrace lines, and the video signal (red, green and blue) are flashing, and the high voltage is present in the crt.
in other words when i dont have video i have red color screen.
