•
This pattern is a color breaking noise that occurs in a DLP system . This is not a
malfunction.

Securely plug the cable connecting the external equipment to the bottom.
•
Keep the projector away from equipment generating interfering radio waves.

a malfunction.
• If POWER can not be turned off, turn off the main power switch and leave the
projector to cool for more than 10 minutes. Then, turn on POWER again.
• On rare occasions, a metallic clank occurs because the color wheel is rotating at a
