Your monitor is no longer in production but there might be some support for it. Go here to see what's available: Product Support You might need to upgrade.

Thats what I did and it worked

check the cable connetor

If Blue colors display properly in pictures or graphics check the display and size settings of your computer in relation to the size monitor.

If there is a problem with the blue color because of a problem with the monitor you might be able to compensate for it either with controls on the monitor or with the control software of your video card.

don't waste your time, the lives of your display is over, get another.

If you're trying to project video, then the unit needs professional service. If you're trying to project from a computer, you may have a loose display cable, broken pins in one or both ends of the display cable, or broken conductors (wires) within the display cable. The computer sends its image information as a template of RED image components, GREEN image components and BLUE image components with the projector overlays to create the complete image with blended color values. (The computer also sends HORIZONTAL and VERTICAL synchronization signals, but those don'e affect the color content of the projected image.) That's why I'm suspicious of the display cable, conductors or pins.

Hi

pls check the board before the color wheel, as it is noticed that this problem comes with the main PCB Board.

The problem is most likely the LCD is dying
