    I received the maintenance manual for my TV (kv36-fv26). Between the AVIA dvd and the manual, I have a pretty good idea about red/green/blue push. I am not sure what the red/green/blue cut do, though. Anyone know, or have a link, to information about this?
    Thanks

    The red/green/blue cuts and drives have nothing to do with red (or whatever) push. They are for gray scale balancing. The cuts adjust the colour of gray at low levels (low contrast) and the drives adjust the high end. Eyeballing an accurate gray scale is virtually impossible, so it's best to adjust these only when using a colour analyser.

    Chris, John was right on about the cut and drive controls being used for grayscale adjustment ONLY. They do not come into play for correcting red push or any other color decoder anomaly. Playing with the DRV controls will alter the grayscale of your display. Do so only if that is your intent.

    Oops, looks like I was getting push mixed with with drv. Greyscale was not my intent, just wanted to bring the red/green/blue levels as close as possible to what the AVIA tests ask. On the AVIA color tests, using the 3 filters they provide, my red is high (25%), green is just about right and blue is a bit low (-15 to 20%). Looks like a lot more research is in order. Thanks for the warning!
