Q The projector doesn't start when I turn on the power. What could the problem be?
A Check the following:
  • Be sure that the power cord is properly connected to the projector and plugged into the electricity outlet.
  • Turn on the main power switch.
  • Check if the lamp lid is open.
  • The airflow passage may be blocked. Check to see if the air inlet/outlet vents or air filter are clogged with dust or another object. If so, remove/clean the passage.

Q Why does the power indicator blink red when I turn on the projector?
A The reason may be one of the following:
  • The projector was turned on again too soon after it was turned off. Wait for the lighting sequence to correct itself.
  • The power switch was turned off while the fan was running, during or after lamp operation. Repeatedly turn the power switch on and off several times.
  • The room temperature is too high for proper operation.
  • If the lamp is not working, it may be burnt out. Replace it with a new lamp.

Q The projector suddenly stopped projecting the image. What happened?
A The projector may have overheated. The airflow passage may be blocked. Turn off the main power switch and check to see if the air inlet/outlet vents or air filter are clogged with dust or another object. If so, remove/clean the passage, and leave the projector turned off for 10 minutes. Turn on the projector and resume.

Q Why is the image projected distorted?
A The projector may not be perpendicular to the screen. Adjust the projector so that it sits at a right angle (90-degrees) to the screen. If the image still seems distorted, try using the Digital Keystone Correction function.

A Check the following:
  • The projection distance may be beyond the focus area capability of the model you own. Refer to the specifications in the User's Manual, and adjust the projection distance accordingly.
  • The lens may be dirty. If so, clean it.
  • The image projection size may exceed specifications. Please check the desired screen size.
  • Brightness and/or contrast may need correction. Adjust accordingly.
