A red or pink tint on LCD monitors indicate that the back light florescent bulbs are about to go out. Just like on regular florescent these bulbs are just much smaller but burn out just the same. Check the date on the back of your monitor, if it is less than 3 years old then its still under warranty but if its not then its time for a new monitor. The bulbs can be replaced but it really is not worth the trouble.
Have you tried replacing the cable first, I had a similar problem with my monitor(only it was blue tint). I would also check and see if the monitors connections are hooked up properly. I hope i could help.
Unplug the monitor cable from the computer and look into the cable where the metal connector are at. Everytime I've had a problem with one color not showing on the monitor, there has been a bent or flattened pin on the connector. Those pins can be bent out but be VERY carefull, they can break very easily.
Check your cable... see if is loose or pins damaged. If you have a DVI connection, switch to that cable. If the cables if OK...Then you need to replaced a new AD Board. Check out this website @ www.3rd-rocks.com They have the necessary replacement parts for your LCD monitor. Have a nice day!
Make sure your VGA cable is seated properly. If it is seated OK, it could be the start of a problem with a backlight. When a backlight goes bad, it typically shows up as pink/red color where white should be displayed.
Check with www.lcdrepair.net if you want a repair. Something is wrong with your LCD controller and or GUI interface circuit or the circuit supplying power to it. If your technically endowed, you may want to open the monitor case and clean the dust and lint from around the circuits using a Small paint brush to sweep away any built up dust. These circuits take the Signal from the computer and controls the 2.5 million pixels on the LCD screen. Dsut can cause major problems with handling all that data. Give it a shot, what do you have to loose, its not dangerous if the monitor is unplugged.
