Monochrome monitor questions?
I'm repairing a few monochrome monitors, these are 9" in size.
The problem I'm having is the screen has vert. lines spaced about every 1/2 in, they are about 1/2" in width. I believe it would be called ghosting? The pc board consist of some discreet components and two IC chips. TDA1175 (vert) and TDA1180 (Hor). Both chips have been replaced as well as the tube. Any ideas what the problem could be, an area to look at? I have a copy of a schematic, but don't now how to post it here for viewing. Thanks.
