I have a VAKO DISPALYS CL501/CS CRT Display Modual. It is a really neat greenscreen display that I want to use for a retro computer project. However I have had 0% luck with this, I have however found the 12V power input & when I power it up the HV works as you can hear the 15KHz. However there is no raster on the display or any other sign of life.
I have tryed to find documentation on line but I have currently found nothing. I don't know if anyone has tips & tricks or has worked with these at some point as it is from 1988, or can help me reverce engineer it as I am not to familour with the nitty grity detailes CRT circitry.
Only IC Is UPC1031H2 Vertical Deflection Driver. The rest of the active comonets are transistors.
I have attached sevrail images to provide at least some context.
