    Per Greg’s request, I’m moving my query here….
    Calibrating Sony LCD sets. I’m having a problem based on the description given in the Service Code section. Getting into the service menu works with no problem, but there is a screen full of red data that doesn’t go away, making it impossible to take readings. Also, when I use 1 and 3 to scroll between options, the choices go away. For instance, if I start on GDRV and scroll up, it isn’t there again when I scroll back.

    There are adjustments in the user menu, but the two sets that I’m working on starts out with the Gains at Max and you can only go down. My sets are deficient Red with no way to add it, making me think I need to do some boosting in the service menu.
    Help please!
    Thanks,
    John Sciacca

    Bring the blue and the green gain down to where the red is. then Red will not be deficient.

    Bumping the gains higher means upping the contrast …effectively … which brings in the discoloration and clipping concerns.

    So generally speaking, if you have a display at 100% rgb, a perfect grey scale, and you move everything thing down an equal amount so now have 313/329 at a lower level, what happens? Does light output decrease?

    If you move everything down equally you are basically decreasing contrast and thus light output.

    Greetings

    Bear in mind that it is never about maintaining max light output at all costs. Remember the light bulbs … a few less … no one can see it.

    regards
