The color temperature presets on my Vizio VX32L all look pretty awful (cool = too blue, warm and normal look too brown), so I've tried now and then to find a decent custom setting using the RGB controls.

I'd like to find a neutral gray like my Sony tube has (9300K standard), since I watch a lot of old B&W films. Unfortunately, this has been fairly difficult, as the ambience of the screen always seems to veer towards red or green or blue, and this color cast remains no matter how long I wait for my eyes to adjust to a new setting.

Anyway, I've found an RGB setting that looks fairly good - although B&W material still looks very slightly green or yellow at times - and the color, contrast, and brightness look fine. The problem is that now the color is unstable and sometimes I get flashes of red, green, or blue on the screen. This is particularly noticeable in old B&W films, where often faces will turn momentarily from gray to light blue or light red or yellow and back again. I realize of course that slight color fluctuations aren't all that abnormal for older B&W material, but what I'm seeing on my screen goes beyond anything I get with my Sony tube.

I'm wondering if maybe these color fluctuations are due to the temperature setting or if maybe I've somehow damaged the screen by adjusting the RGB controls too much. It wouldn't seem possible you could damage an LCD screen simply by adjusting the color as the screen is constantly changing colors anytime you're watching DVDs or cable.

I've thought of course about using a calibration disc but I don't know if DVE or Avia could help me adjust the color temperature any better than I can on my own. It may well be that this Vizio simply isn't capable of displaying as neutral a gray as my Sony, and that I'm always going to be stuck with some annoying color variations no matter what setting I use.

Just sounds like cable issues or the TV simply has something wrong with it. Moving toward being broken ...

Seconded

I would first try a different cable, then if that doesn't work, a different input. Then if that doesn't work, then i'd suggest the tv is on its way out.

FYI,
Old B/W movies are best viewed at 5400 kelvin.
It matches the color characteristic of the projection lamp back in the day...

but might look "right" at d65 (6500k) depending if the image was color corrected when it was tele-cine'd and mastered.

Some B/W films look blue at 6500k others look normal, and some look "sepia" at 5400k and some normal.

So you cant just say B/W films are best at 5400k even though the lamps on the film projectors from that era were 5400k color temp because we are not watching them on a film projector.

There is also the "silver screen" effect to account for since the old time movie screens weren't a "netural" white but instead had a silver color cast versus a pure white, so it is had to say what color temp B/W material is thus its best to set a preset for B/W that is 5400k for the film that don't look proper at D65

Even 6500K looks too brown to me. Of course I know 9300K isn't correct, but after decades of watching tube TVs fixed at that standard, my eyes see anything else as wrong.

Do you know of any specific b/w DVDs that look "right" at d65 and
any specific that should be watched in 5400k?

If it looks kinda sepia reddish with a D65 setting ... then it has been corrected. Otherwise it has not.

Gotta train 'em. You may find it will open up a whole new world for your viewing experience.

Very good points.
Unfortunately, unless the packaging is marked or you have the Director's digits, it will be a guess at best.

This is particularly noticeable in old B&W films, where often faces will turn momentarily from gray to light blue or light red or yellow and back again.Are these color changes mainly noticeable in the brighter areas? If so, maybe you have either the Contrast/white level set too high on the LCD, or Dynamic Contrast enabled (which could also clip or crush the white detail).

Changes to the RGB settings could easily be enhancing this effect as well, because the further you move away from the LCD backlight's native color temperature, the more obvious the clipping will be when the white levels are overdriven.

You can get a better idea whether the problems are source, or display-related by turning Color saturation down to the lowest setting on the LCD. If the problems still exist with the Color turned off, then it's probably not source-based, and is likely a display-adjustment issue like the above.
