clean the dust out of it with canned air and make sure the fans all spin. the dust keeps in the heat that the projector is trying to expel.

3m S50/X50 - purplish hue


Hi Larry

Try using a different RGB cable , if this doesn't fix the problem you will have to get the Mainboard of the Projector either repaired or replaced.

3M S151 Projector for the classroom


You will need to have a dvi to vga converter. If you have a Macbook, it is a mini dvi to vga. You can get this adapter direct from Apple for about $20. A wireless connection is not available with this model projector.
