IF you are interested in going into service mode, there are excellent test patterns there. Glen's advice is just fine. If you want to be more wirehead about this, here is a partial repost of the original information from way earlier in this thread. There is a fine grayscale step-scale pattern, but its format may not be the best for judging deepest blacks. I'd go with Glen's advice.
THis doesn't appear in any service manual I have seen. Enter service mode, and step *backwards* with the 5 key to see these groups. My 36XS955 has the service-menu group called "QM." It comes up in blue, not green, and AFAIK the values are never saved. Further, 0 - Enter reloads everything and kills the patterns, rather that your having to run the PATN count down to 0 before exiting. So does power-off.
Fair warning: Turn your sound down to zero before going for any patterns; a loud audio test tone is part of this. When you are showing one of the patterns, you lose ability to change picture modes and a couple of other things. Further, you have to return to QM/PATN and run the value back down to 0 to get the patterns to disappear. A bit tedious, but I'm not complaining about having built-in HD patterns!
#0 - INFO (values 0-7) has 7 screens of information about what is going on in the set. Nerds, rejoice!
#1 - PATN (values 0-80) has four groups of 12 patterns, both color and b/w, including a couple of amazing frequency sweeps, color bars, grayscale steps, crosshatch patterns, etc. Each pattern is at value 20*n + p, where n is 0-3 for the video-mode group (see below), and p is 1-12 for the pattern. (The remaining values are pure-white screens.) I used the top=blue, bottom=gray screen for adjusting the color intensity for the different video modes represented, especially HD.
The groups on my set are for 1080i, 480i, 480p, and 720p, in that order.
#2 - GPTN (values 0-12) are 11 different patterns of a decidedly different type on only the upper 70%of my screen, no matter the scan rate. Some are translucent. I don't know their specific purpose.
QM has more codes, but I haven't discovered anything about them yet.
The test patterns are inserted into the video channel *ahead* of all picture adjustments in 2170P-3 and MID5, so they can be used for evaluating these settings. I value the crosshatch patterns, but some of the others I will probably just look at for fun, as we don't know what pathway they take thru the long processing chain. I wonder what the sweep frequency extremes are for the #8 patterns in each group. Unfortunately the highest video frequencies are positioned at the right edge of the screen, where the horizintal focus is the worst!
