CT-100 color sync issue?

[Phil Nelson]

I'll give those tubes & sockets another good cleaning. Like a two-year old's face, there no such thing as too clean!

Perhaps something's off in the front end. It's notable that the fine tuning point for best color bars and best DVD (or whatever) image are not the same. When I switch from generator to DVD player, I don't even get a picture until I turn the fine tuner somewhat.

Saying "best" tuning point for color bars sounds more precise than it is. One color or another will change as you move the fine tuner slightly, so I go for the best compromise (largest number of colors closest to ideal). Magenta is usually the hardest to get close. Perhaps there's a more scientific way to tell when the fine tuning is set to the right frequency . . . ?
