    hey guys -- i have a daewoo HDTV and only yesterday for no reason when i plug my Macbook white 2.2 into it has this darkish blue tint appeared.... the macbook is normal while the TV has the tint

    the tv has worked perfectly before for 5 months! i ve tried different pc monitor cables.....could it be the short white MAC adapter? i have not changed any settings

    going into "display" and chaging the resolution/ frequency does nothing

    please someone help

    edit!! update! just been fiddling around with the color profiles and it seems to brighten it up and darken the contrast but the colour red is being shown as a dark blue.......and it still has a tint

    check out the image in the link below, it gives you all the basic colors (red, green, blue) plus the secondaries (cyan, magenta, yellow)

    that will tell you if one of the colors (looks like might be red in your case) might not be working.


    try turning everything off, and unplug all the video connections and plug them in again to make sure they're all well seated. then power it all back on.
    something might just have gotten scrambled in the mac, i had the display on my MBP go purple when i woke it up once, a restart fixed it.

    waw74's suggestions are what you should do, but just to check, is it connected via a VGA cable, or something else (HDMI/DVI or video)? Assuming VGA, I've seen exactly that symptom when the physical connection is bad, dropping out one (or more) of the colors (as said, red in your case). Sometimes you can just tighten the thumbscrews, but it could also be a broken cable and/or adaptor.

    If you have a second cable around somewhere to test with, that would be something else to try if waw74's suggestions don't get you anywhere.

    well this is what it looks like - I think i might find a few more VGA cables! If not then it must be the adapter

    damn it!! I had no problems up until a few days ago

    any other suggestions --

    Same Problem, adaptor!!

    Hi, I have the same problem, and it is definitely the adaptor in my case. When I wiggle the cable between the DVI to the laptop and the VGA to the cable that runs to the monitor, it goes from normal to blue. I think it is because I always have the adaptor leaning off a table and pulled down to the floor. It has messed up the connection. Try getting a new adaptor. I have done so, and the problem is resolved!

    Just an FYI in case this comes up for anyone else doing a search. Monoprice.com has these adaptors really cheap. Buying another "official" apple adapter at retail makes me cringe, but the price at monoprice makes it much more bearable.

    I've had good luck with my adaptors so far, but since I use mine frequently with projectors and carry them around in my notebook bag, I'm sure they're going to wear out at some point. That's why I always carry two.
