The bars on the left of the screen are caused by horizontal ringing, usually a symptom of excessive drive. Reduce the drive with the drive pot/trimmer if there is one, if there isn't one you'll have to tweak the values of certain resistors in the horizontal oscillator circuit. Also check horizontal current drain while you're at it (should be a small value resistor on the h-out tube's cathode), it's likely out of spec. A clue will be the height of the waveform going into the h-out tube, so scope the grid and bounce it off the schematic. The other stuff looks like 3.58mhz dot crawl to me, but I could be wrong. If it is, there may be a trap you can adjust in the video chain somewhere. Again, look for a slug you can tweak in the schematic. If there's no 3.58 trap, you'll just have to live with it unless you are able to feed it video from the Y component jack of a DVD player or cable box (the Y line is B&W only, so should provide a clean source).
