    Happy New Year!!

    I am calibrating an older Toshiba 42HL167 LCD tomorrow and I saw some chatter about ‘funny’ things happening after changing SM values. The only controls this set has for WB in the user menu are B/G gain and I didn’t know how effective they were, so I took a look at the Service Manual.

    In the Service Manual I see R/G/B cuts and drives and they look innocent enough, but I when I did some research and background reading on this, I got a gut feeling that adjusting these parameters in the SM may cause more problems than they’re worth.

    Anyone have any input/suggestions?

    Thanks!

    Best,
    Greg

    use the user menu only….it should be fine…
    if not..then look at the service menu…ensure you write down your starting data points prior to making changes.

    Weird how times change….10 years ago 95% of my work was on Toshibas….now less than 5% is on Toshibas (or even less).

    Thanks so much for the advice, Gregg! I’ll see how it goes in the UM first.

    That really IS quite a shift in Toshiba calibrations, isn’t it? Tells you something, I guess…

    Appreciate the tip,
    Greg

    Just as a follow-up: The calibration actually went pretty well.

    I did, in fact, have to use the Cuts/Drives in the SM since the User Menu B/G drives didn’t quite give me a good enough grayscale. I didn’t run into anything quirky in the SM, but I did after using the ColorMaster (CMS) brightness controls in the User Menus. As soon as I touched those and went to view some content, the picture was grainy and contoured as all get out (as noted on the AVSForum by several users)! So, I just had to zero out all the brightness controls in the ColorMaster. The Hue/Sat helped the gamut a bit, and I couldn’t get it adjusted perfectly by any stretch of the imagination, but the color gamut on this TV was better with the ColorMaster on and somewhat adjusted than with it off.

    Not a bad picture after calibration, but it’s an older LCD with all the accompanying shortcomings.

    Thanks again for the input, Gregg! (With luck, I won’t have too many requests to calibrate more of these, either. 🙂

    Best,
    Greg
