I have a small (4.5") monochrome CRT in a piece of process monitoring equipment that is not working. No video display. HV seems to be good, filament is on. Even if I turn the brt and cont pots I get no raster. Thinking it might be the video amp section?
Going to try and contact the company tomorrow. It was made by Wintron who seems to have been absorbed by Video Display Corp. I am not expecting much.
If anyone has any ideas I am all ears.
