4.The projector will power down if the lamps were installed incorrectly or have failed. If the projector powers down during lamp replacement, it likely indicates the interlock has been in the open state for more than the allowed 2-minute time frame. During a hot swap, make sure to install a lamp (good or bad) back into the lamp compartment within 2 minutes otherwise the projector will power down.

2.The horizontal or vertical scan frequency of the input signal may be out of range for the projector. Refer to Section 6, Specifications for scan frequency ranges.

3.The sync signal may be inadequate. Correct the source problem.

CAUSE / REMEDY: 1. Brightness and/or contrast and/or gamma may be set incorrectly.

2.The source may be double terminated. Ensure the source is terminated only once.
