whether images are projected correctly. If images are projected correctly, use an RGB

signal ampliﬁer along with the extension cord.

Images are not displayed correctly.

Problem Solution

Projected images are

shaking.

Projected images are

displaced.

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

• Connectthecable’splugwiththeexternaldevice’sconnectorrmly.

• PresstheAUTOPOSITIONbutton.

Afterimages persist on

the screen.

• This phenomenon is improved by keeping projecting an evenly bright image. (Such

“image burn-in” phenomenon where afterimages persist on the screen may occur if a

stationary image is kept displayed on the screen for a long time.)

White dots are seen

on projected images.

Black dots are seen

on projected images.

• ThisphenomenonisnormalforaDLP™projectorandisnotamalfunction.(Avery

small number of pixels may visibly or invisibly be persistent all the time, but they are

notasignofsystemmalfunctions.Over99.99%ofthepixelsareeffective.)

Fine streaks are seen

on projected images.

• Thisisduetointerferencewiththescreensurfaceandisnotamalfunction.Replace

the screen or displace the focus a little.

• Verticalorhorizontalstreaknoisemayappearontheprojectedimage,dependingon

the type of the DVD player, game console or computer you use. In such a case, you

can reduce such streak noise by enabling the LPF.
