To avoid a possible wild goose chase, it might be worthwhile to ascertain that the bars are deflection-based, and not in the video chain. Shunt the CRT control grid to ground with a cap, which kills the video. If the bars are unaffected, they are in the deflection system. Cap value not critical, anywhere from .047 - .1 or so.
