/diy/ - Do It Yourself

If you could help me out that would be great. Heres the rundown
I'm getting rainbow banding when I watch a tape, and more accurately, I get these blue and red bars when I SHOULD be getting a pure NTSC signal bar display.
I replaced the 3.57mhz crystal already. I used a scope to make sure the amplitudes and levels were correct >>1707678
I finally got a frequency counter which then showed me the 4.27mhz crystal is way off

Basically I just want the color to work again so I can copy some of these tapes digitally, and then rid myself of this unit once and for all lol. Its a 1970s Quasar VX machine. There's a few on ebay that are going for over $300 broken and one going for over $700 brand new but I'm not that desperate.

well, not so good news. the colors havent changed at all. but the scope is at least showing the correct waveform now on non-aft mode
