|Where is a good place to start. My 9PG Plus projector showed up with all w and b settings at 50%. No detail in dark areas and flesh tones look more red. Are you talking about running one color at a time making adjustments for black and all three for white or am I missing something. What are typical numbers for this PJ with 5,000 hr tubes? I've never tried the by eye gray scale method|
I don't really recommend doing this by eye, but without a technician's expertise and the right equipment, this is the next best procedure IMHO. To start with make sure you have the Contrast and Brightness set properly. Again, I would turn to the AVIA DVD and use the Needle Pulse
Pattern seen here...
The bars on the right hand side of the screen move back and forth so they can be easily seen. To adjust the brightness (black level) look at the top half of the screen at the black moving bars and adjust the brightness until the left bar is the same shade as the background and only the right bar is visible.
Now to adjust the Contrast, again look at the white moving bars at the bottom right and adjust the Contrast until only the left bar is left visible and the right bar becomes the same shade as the background. You may have to go back and forth between the Contrast and Brightness until you achieve the proper levels.
Another tip regarding this procedure, if both black bars are not visible then the brightness is set too low. If both black bars are visible then the brightness is set too high. The opposite is true with the Contrast. If both white bars are visible then the Contrast is set too low. If both bars are not visible then the Contrast is set too high.
Now that you have Contrast and Brightness set properly, now you can put up the Vertical 10 IRE Steps
pattern and again try to adjust out the White and Black levels to achieve gray steps that do not contain shades of anyone of three dominant colors (RGB).
Hope that helps a little.
