One thing he doesn't explain is you also want to adjust the playback video amps (the pots were labeled 1H and 2H PB level) on the YC-L board under the playback mech. You want to connect the RF out of the deck to a TV to do this instead of using video out (the monitor I was using wouldn't show the issue on the video input). Basically you want to use the decks tuner to see what normal video level should be (brightness wise) then hit play and adjust 1H and 2H to take the excessively dark video, that you'll probably find you have, and return it to a normal brightness level comperable to what the decks tuner gets.

IIRC I bought a Zenith SVHS deck off of you...The same VCR repair kick I recently was on that fixed the Beta decks also fixed that SVHS (though I had to part out a working Zenith VHS-HiFi deck with the same mech to that).

I watched that guy's SL7200 video last week hoping he would run across that color issue, but that one worked fine after he got the mechanical issues sorted. Looks like I just picked the wrong video.
