Blake PattersonThere have a vertical linearity issue on this CRT I picked up last weekend. It's a Magnavox "Computer Monitor 80" with no model # on the case anywhere, but I believe it's a Philips BM7500-series, or so.
(See the bottom 3-4 lines of text vs the rest of the text on screen - vertically squished.)
Here is the service manual as close as could be found,

Can anyone tell from the schematic if there is a V.LIN pot on the board somewhere that I would find upon opening the unit? I'd like to get it adjusted and use it.
If it's a caps issue, I wonder how many would need to be replaced to get it back to snuff? This display was manufactured in late 1986.
