What is Red Push?

[tlrich]

I have heard people posting about "red push", how someone might have too much of it, but I don't know what it is or how to adjust it. Can anyone explain it to me?

I have a JVC AV48WP30.

Thanks,
Tlrich

If you don't see it, there's no need to adjust IMO.

red push - Tendency of the color decoder in many TVs to accentuate the color of red compared to blue and green. Red push is typically introduced intentionally to compensate for an overly blue color temperature.

When using Avia DVD, the process is relatively simple. You navigate through the menus of the DVD to select the correct grayscale window which range from 0-IRE (black) to 100-IRE (white). In a dark room, with minimum lighting and resulting reflections, you carefully go through each gray window from black to white, and use your eyes to see if the image appears to be gray or have color intrusion. The most common color intrusions seen are red in the darker images and blue push in the lighter images, but please remember this is NOT Red Push or Blue Push. Red Push is related to color and hue, not grayscale. While in each window (black to white), it may be easy to see colors bleed through. If colors are visible, you access the service menu and adjust the correct setting to reduce that color. In some cases, colors may need to be increased in order to make gray look gray. While this process if effective and helps improve the TV's performance, it's not nearly accurate enough to achieve 6500K or D65 as it is more guess work then science. Even the best eyes can not detect enough to determine if the settings are near 6500K as our eye can not accurately detect almost drastic differences in the luminance of bright images such as white.
