Make sure the color wheel cable is connected
The color wheel cable must be fully inserted into its ZIF connector. To check the connection, hold the
cable with a tweezers and gently tug on it. The cable should not move. If the cable moves in and out or
side to side in the connector, it probably is not making good contact. Release the latch, re-insert the
ribbon cable, then tighten the latch.
