The projected image has inverted colors.

• When the cable was manufactured, the Red, Green, and Blue pins were switched causing colors to cross over.
• A new VGA cable should correct the distorted colors.

The projected image has a blue, pink or green tint.

• The projector lamp needs to be replaced.
• If a new lamp does not correct the color issue, the projector is in need of manufacturer repair.  Most projectors have a 3 year manufacturer warranty.
