Hey all,
This may be semi-OT, but has anyone messed with the black and white TV sets used in early Atari cabs? More specifically, my Quadrapong has a Zenith 19EB12 that has issues with vertical hold, horizontal hold, and vertical linearity. The horizontal hold seems to settle down after the thing is on for a minute, so immediately I'm thinking bad caps, but there's only 1 electrolytic on this thing that's already been replaced. I've never worked on a monitor/TV of this vintage and I'm open to any suggestions, including possible replacement ideas. I would think I could find another TV with VHF and UHF inputs as a replacement. I did pick up a 13" B/W with those inputs at a thrift store, but I can't get any picture out of it that's even close. Any advice or input would be appreciated. Thanks!
