Troubleshooting (continued)

Images aren’t projected correctly.

Problem

 

Cause and solution

 

 

Projected images are shaking.

• Check that the cable connected to the external device isn’t intermittent.

Connect the cable’s plug with the external device’s connector firmly.

Projected images are displaced.

Press the AUTO POSITION button.

 

• Some computers output out-of-spec signals on rare occasion. Adjust the SIGNAL menu. (See page 19.)

 

 

 

Projected images are distorted.

Adjust the projector and the screen so that they are perpendicular to each other. (See page 12.)

 

 

 

• Adjust BRIGHTNESS in the IMAGE menu. (See page 18.)

Projected images are dark.

• Replace the lamp. (See page 22.)

• Remove the lens cap.

 

 

• Check SET UP function in Signal menu.

 

 

 

• Adjust the focus. (See page 13.)

 

Clean the lens.

Projected images are blurred.

Remove the lens cap.

 

• Adjust BRIGHTNESS and CONTRAST in the IMAGE menu. (See page 18.)

 

• Adjust the projector and the screen so that they are perpendicular to each other. (See page 12.)

 

 

 

White dots are seen on projected images.

This symptom is normal for a DLP projector and is not a malfunction. (A very small number of pixels may stay

Rainbow blur appears in projected images.

This is due to color breaking noise that occurs in a DLP system and is not a malfunction.

 

 

Fine streak pattern appears in projected images.

• It occurs because of interference with the screen and isn’t a product malfunction. Change the screen or read-

 

just the focus of the projector.

 

 

 

 

 

• Connect the cable’s plug with the external device’s connector firmly.

Projected images (and/or audio) appear wavy and

Tint in projected images is incorrect.

• Check that COMPUTER INPUT in the SIGNAL menu is correctly set. (See page 17.)

• Check that the cable connected to the external device isn’t broken.
