Re: Syncmaster 913v color problem
Appears to be something in the connection. Check the video cable and pins on the video connector. Also verify the color settings have not been changed on the monitor. There should be an area where you change the RGB levels.

The problem can be caused by bad caps in the power supply, bad inverter circuits, worst will be bad lamps. Look inside for bad caps first, report back what you see so we can guide you further, see example of failed monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums
This problem often occurs in samsung SyncMaster LCD monitors.
solution is open your look for the LCD monitor power supply module
(which have PCB connector to the AC power), on that board look for
capacitors, now look for broken one which upper part is bloated, like
the image below:
If you find a damaged capacitor as in the picture then you should replace it with the same value.
Looks like u have lost one or more of the color channels (RGB) make sure the video cable is plugged in securley (both ends computer and monitor) and locked down with the screws, restart the computer and monitor.If this fails check video card and then monitor, can u plug the monitor into another computer this will determine if the monitor is ok or not. If monitor is ok then problem most likley will be the video card.
Either you messed badly with the system color profile management, or, more likely, the VGA cable is faulty or improperly seated. Try unhooking the PC end of the cable (and, if you got yourself a model with removable cable, also the monitor end), and hook them back again, seating the connectors gently but firmly and tightening the connectors' retainer screws.

Check the video cable connection at both ends. If it is secure, then move the cable in circles at both ends.
If the cable breaks a single wire, it will still be close enough to make contact under this test.
The red is almost always the one that will break first and cause the green and blue signals to be the only ones to be active resulting in a blue/green tint.
If you have another cable just try that instead.
Most likely it is your VGA cable gone bad. I remember doing a warranty call for HP once, I was the third tech to go out and replace a motherboard. When I got there, I found out that the cable was bad and it was giving everything a blue tint. I would certainly recommend replacing the VGA cable. I bet if you wiggled the VGA (monitor) cable on the back of your computer, it will come and go.
