Check
• If the picture is normal, the sound is due to cabinet shrinkage caused
by room temperature changes. This will not affect operation or
performance.
• See “Maintenance Indicators”.
• The keylock is set.
If the keylock is set to “ON”, all the buttons are locked.
• Change the input signal type setting.
• When you cannot select an input signal type, select “Color is faded
or poor” in the “Help” menu, after selecting an item other than
“sRGB” in “Picture Mode”, and then select an input signal type.
• Image adjustments are incorrectly set.
• When temperature inside the projector increases, the cooling fan
runs faster.
• The lamp indicator is illuminating in red.
Replace the lamp.
• Cables are incorrectly connected to the projector or the connected
equipment works improperly.
• Select “Vertical stripes or flickering image appear” in the “Help”
menu and make the necessary adjustments.
• If this happens frequently, replace the lamp.
• The lamp will eventually need to be changed.
While the remaining lamp life draws to a close, replace the lamp.
• Operate the remote control while pointing it at the projector’s remote
control sensor.
• The remote control may be too far away from the projector.
• If direct sunlight or a strong fluorescent lamp is shining on the
projector’s remote control sensor, place the projector where it will not
be affected by strong light.
• The batteries may be depleted or inserted incorrectly. Make sure the
batteries are inserted correctly or insert new ones.
