    I've got a CRT monitor that's pretty old (approximately 3 years) and for a long time now, it has been tinted pink. More recently, it has been tinted blue and sometimes it will revert back to the pink tint. I Googled this problem and got this:

    I checked the cable and it seems to be fine. However, I don't have another monitor to use. Is it true that this problem cannot be fixed?

    In another forum, one user said that he simply slammed a hand against the side of the monitor and the problem was fixed. I did that and the tint went from pink to blue. I did it again and the blue did not go back to pink. So, is something wonky inside the monitor and do I really have to get a new one?

    Yeh, you probably need a new monitor. However, it may be the video card causing this.

    Usually it's a "dry joint" (a poorly soldered connection) somewhere in the monitor. That it changes behavious with the "percussive test" tends to confirm that.

    These are not able to be detected by eye usually, they look quite "normal", so diagnosis and repair often cost several times more that another monitor.

    It could also be the cable from the card to monitor. Check that there are no loose or bent pins on the cable, and examine the length of the cable for kinks or tears. Also try squeezing and bending the cable near the point it connects to the video card while the computer is running to see if there are internal breaks in the cable.

    If it were the cable, you could fix it, or rather get it fixed by a profesional.

    I have found on 2 different monitors, that there is an anti-magnetic button that needs to be pushed occassionally. Our granddaughter has a gateway that was REALLY PINK and after I used the button a few times, it corrected itsself.

    The3 button you refer to is the "degauss" button.

    It demagnetised the CRT shadow mask, but as the original poster mentions that the situation suddenly changes with the percussive maintenance (whack) then I would not expect it to be a magnetisation issue.

    A screen in need of a degauss will have blotchy colour usually (colour purity over parts of the screen), seldom complete screen tinting.

    The poster did mention that the cable had been checked, as I recall.

    Checked. Tint's still present.

    I've also degaussed it several times, but to no avail.

    Also, it doesn't always change colours every time I do the 'percussive test'.

    Is there absolutely no other way to get rid of this problem? I'm your garden variety broke college student.

    I can get used crt's in and around vancouver for about $25. Thay usually arent that great and are far from reliable, but they are not $150. Keep your eyes open and shop at Value Village or other thrift stores. Otherwise, you could seek out a pro who would look at it for free and give you a price for a fix.

    Post a bulletin at the college, "looking for a free monitor; will pick up and buy beer!"
