My monitor had a beautiful white screen and eventually turned yellow, it has now turned to a light shade of red. What could be causing this?  Or how can it be fixed?

I hade a monitor like that ounce i would hit on the side and it would fix it for a while.heheh
But realy sounds like you got a real proublem. There are the three color controls in the back and it sounds like one of them is going bad.
you can take to a tv repare shop or a computer tech and proubly get it fixed or you may have to get a monitor.
BTW i had to get a new monitor.

This is a common sign that the monitor is old and hurting. 1 possiable fix may be to take the cover off of the monitor and (with it unplugged) blow out all of the dust. Dont use a high pressure compressor or anything but maybe some canned air. Be careful not to damage any of the settings on the tube (they are the plastic pieces right where the tube connects to the board). If it is really dirty then that can cause the monitor to get very hot in places it doesnt need to. There are also alot of additional settings inside of the case that you can adjust for color- one of them may be going bad.

DON'T OPEN THE MONITOR UNLESS YOU KNOW WHAT YOU ARE DOING!!!!  This is really dangerous.  You can get killed because there is a charge so powerful that it can blow you clean across the room.  The charge will stay even if the monitor hasn't been plugged in for many many years.  Anyway, what you problem seems to be is that the monitor must have been pressed up against a wall.  The cord that runs either out of the monitor or out of the computer has been squished and craked some of the individual wires inside.  If you try, while the computer is on and the monitor is on, move the cord around either the spot where it is connected to the monitor or the spot where it is connected to the pc.  If you find the colors then change, the cable is junk.  If you are one of the lucky ones and the cable is unscrewable, just get a loan of a new cable.  If that doesn't work, try the monitor on another computer.  If that doesn't work, either take it to a repair shop (expensive) or purchase a new or second hand monitor.  If you are purchasing a monitor, remember to buy one that allows you to unscrew the cable from the monitor.  I have had the same problem and the monitor goes from yellow to green, to red, to purple.

My monitor is sitting on a desk that is at least 5 feet from any wall, which means the monitor has been in plenty of free air space.  The cables look fine and are not squished against anything.  So the problem is coming from something else.  Thanks for your help.

Thanks for your help, but I think I would rather take it some where to have it looked at rather to go in it myself.  I'm thinking that it would probably be just a cheap the purchase a new monitor than it would to have it looked at and repaired.

Well I'm confused as to why I got the points if it didnt answer your question, but I'm wont complain!. Anyways to whoever made to post about getting killed or something. There is the main wire conecting to the tube that can carry like 10k volts of electricity; however just because you touch it doesnt mean your gonna die or for that matter even cause a discharge (get shocked). Its not the amount of voltage that hurts you its the amps!!! So if you really want to get technical you can take a pair of pliers and pull the spring clamp (which is how that big red wire connects to the tube- located under the rubber seal) and pull it out. The tube just wont discharge unless you short it or use a discharging tool- but that also doesnt mean go do it- because people like you may get hurt
