Don't use black tone.
Try the following:
Mode - Movie
Color - 50 (or default), t
Color tone - Warm2
Tint - 50/50 (or default)
Sharpness - 0 (anything except for 0 or sometimes 1 will create artifacts/distort in games and videos)
Black tone - off
Dynamic anything - off
HDMI level - Low for gaming consoles, satellite TV, cable, BD players. With this setting, your lowest black = 16, and your highest white = 235
HDMI level - Normal for PCs. With this setting, your lowest black = 1, and highest white = 255
Backlight - 4-6 (or default)
Brightness - set to 50 (or default) for now
Contrast - set to 90 (or default)
Gamma - leave at default
Don't raise your backlight that far just yet. Backlight can raise and lower black levels, but it cannot crush/clip either. It should be the last thing to set after you find your black and white levels.
Using the settings I provided, use the Disney WOW disc to calibrate. You want black level 16 (if HDMI level is set to Low) or 1 (if HDMI level is set to Normal) to be barely visible/flashing. The same thing needs to happen with white level 235 (if HDMI level is set to Low) or 255 (if HDMI level is set to Normal).
I do not know exactly what the pattern looks like but it should provide at least several shades of black, including levels 16, 17, 18 and you should be able to distinguish them from each other. The pattern should also provide several shades of white - 233, 234, 235 and you should be able to to distinguish them from each other. To do so, you need to adjust only contrast and brightness.
Use brightness to find your lowest black and use contrast to find your highest white. Leave backlight alone for now. Once you find your lowest black using your brightness, look for highest white using contrast. Raising contrast will also raise your black levels. Just to give you an example, let's assume you reduced your brightness from 50 to 48 to get to your lowest black while keeping contrast at default (or 90 as an example). Then you started to lower your contrast to find the whitest white and you found it at 85. By reducing contrast from 90 to 85, you may have crushed your blacks. If so, go back to brightness and raise it until you find your new lowest black. Doing so may clip your whites and if it did - go back to contrast and find your new highest white. So, going back and forth until you can get both right.
It would also be helpful if you have a pattern like this one - http://www.lagom.nl/lcd-test/contrast.php
You do not want to have a contrast so high that you can't distinguish each shade on the right side of the pattern or have contrast so low that you can't distinguish each shade on the left side of the pattern.
You should try to keep your brightness as low as possible and contrast as high as possible, while taking in consideration the overall luminance (commonly referred to as "too bright" or "too dim"). I find it best to use backlight to achieve that right luminance instead of reducing or increasing brightness & contrast. By keeping your contrast high and brightness low, you keep a higher contrast ratio. So, if you decide to use contrast and brightness to set your luminance, you may end up with lower contrast ratio. Some find it to be quite important to have the highest possible contrast ratio. Others do not.
However, nothing of the above will provide you with an accurate picture unless you actually buy a colorimeter and learn how to use it with HCFR or ChromaPure or CalMAN. You can also hire a professional to do it for you.
