Touch up welds on the socket filament pins and on the respective flyback pins (Heater). Make sure the presence of filament voltage (5vAC) in both the socket and the flyback pins. If the symptom persists, observe if you turn on the filaments inside the CRT barrel. Measure SCREEN when it looks good and then when the screen darkens.

Both the socket and the flyback are sometimes marked with the letter "H" (HEATER)

With a magnifying glass check the insert that goes behind the screen and where there is false contact or welded welds and re-weld them as much as the strap pins and those of the motherboard that fault is of a false contact and checks the filter 250v 10
