I recently acquired a Sony PVM-8041Q for a great price but it's got a major issue: there's no vertical at all, beyond a thin line. I'm sure that this is caused by failed passive components but where exactly should I look for said components? I don't really know how to read electrical schematics but I do know all the pots for adjusting the horizontal and vertical settings are on what the service manual calls the "D board". Maybe someone can help me make sense of this manual and help me figure out what to replace to get the picture working again?
