Don't tweak the ones other than already mentioned unless they are labeled, you know they need adjustment, and you know how to properly set them.....A modulator is essentially the opposite operation of a TV tuner/IF system, and just like a tuner IF system if the adjustments don't look like user controls then they should not be casually messed with.

Try lowering the Video, audio, and aural carrier levels, and see if the interference goes away.

Also there should be a short IF patch cable on the back connecting 2 75ohm jacks together...Try another cable in it's place (the one it came with may be damaged).
