Adjust Grayscale via Remote
vs. Trimpots
<< Back to Hitachi Tips
Tip from Tom B: "The SWX and UWX sets DO
have remote control perameters to adjust the low level brightness grayscale. In
other words, you CAN adjust the "cuts" with the remote and not have to touch
those nasty trimpots.
Always write down the original factory number for the setting(s) so you can go back to
it if necessary. I don't want you to "mess anything up" on your set.
It would be best if you could check out the service manual, page 31, but if you don't
have it, maybe this will do. It is nice to know though that there is a "factory
reset" selection choice at the bottom of the OSD adjust mode.
- To access the Adjust mode OSD, open the small door on the front of your set and press
INPUT + POWER.
- The service manual specifies that all adjustments should be made in the "COOL"
temp. setting with all video menu settings at 50% except for contrast which should be set
at 100%. I can't bring myself to set my contrast at 100%. You suit yourself. Press
"up" or "down" on the toggle blue button on the remote to navigate and
select R(ed) cut, G(reen) cut, and/or B(lue) cut.
Again, please write down the original number setting for each cut before you start to
adjust. Press "left" or "right" to adjust the selection. You
will , of course, have to have something as a reference to use to set your color.
In other words a frame from a movie (paused) with the ugly green in it that you know
should be gray. I'm sure if a ISF Tech. reads this, he will die laughing or pull his
hair out at this primitive suggestion. There is no doubt that it would be much , much
better to enlist his services!!! I use an 18 % gray card illuminated by a 6500 degree
Kelvin florscent light to help set the color of gray. ( The same bulb I use for
backlighting my set)."
