    Problem! I finally restored a family member's 2006 MacBook, and the only part that still isn't working is the monitor. No big deal there, because I purchased a Mini DVI-to-VGA cable to use with my monitor and TV's. Everything works now (I unplugged *the display cable and the backlight cable from the logic board so that the monitor would be the only display, but my problem persists even when the cables are plugged back in), except for one annoying thing.

    On every display I plug into, without fail, there's a distinct blue tint. A great example of this is the desktop background: what is normally the standard purple Snow Leopard wallpaper looks like a blue version. There's obviously some connection problem, because the computer doesn't natively do this (example: when I use a remote desktop client like Splashtop, everything is normal).

    Anyone have any experience with this? Is it a problem with my Mini DVI-to-VGA, or is this something wrong with the Mac. And more importantly, if it is a problem with the Mac is there anyway I can fix it WITHOUT having to buy replacement parts?

    So to summarize, I have a 2006 MacBook with no monitor access, and a blue tint whenever I plug it in to an external display. Any advice for getting rid of it?

    Off the top of my head there are two possible caused.

    The first is, as you said - a bad connection (most likely the actual adaptor to VGA)

    Another option - in System Preferences, on the displays screen have you tried calibrating the monitor color? Even if it is the cable it *may* be possible to rectify it through a custom color profile.

    Everyone I've talked to suggests these same two possibilities. I did try for custom color profiles, even tweaking them in ways I knew weren't ideal, with no success.

    I've also looked at the VGA-end of the adapter. I don't see anything obviously wrong, so unless it's not something I'd notice easily, the adapter is fine. I may try to exchange it later today, though.
