Zeno:

There is a knob marked Black Level. I assume this is the brightness control (as there isn't one called brightness and it seems to function as such). There is also a knob labeled Picture. I assume this is the "contrast" control. I did not find anything else in there to adjust with a screwdriver.

You mentioned bleeding... is this the red shadow I get to the right when turning up the contrast? It does exist... only if I turn the contrast up too high. I've seen this before on my Curtis Mathes set, but only when the picture first comes on. Typically, it goes away within a few seconds.

I agree with you... the picture overall looks better with the Color Sentry turned off.
