    Hi,

    I've been having a go at calibrating my BG808s using the SpyderPro and Optical and have a reasonable grey scale from 20 to 70ish IRE. Now as expected the blue gives up at about 80 IRE with a contrast setting of 46 and blue de-focused. The picture is looking good but is low temp at 100IRE (low blue) and I would like to get the grey scale within +/-300 degrees across the range (accepting the Spyderpro is not a precision instrument).

    I read that the Lumagen has a service menu item that allows you to change the gain setting of the rgb signals at various IRE levels. This is to allow you to bring the blue back inline after you have thrashed it to get the 90+IRE output.

    Has anyone any info on doing this please?
    How do you get to the service menues in the lumagenPro?

    Cheers,
    Brian
