Troubleshooting (Cont.)

Symptom

Specific colors fail to be displayed.

The upper part of the video image bows or distorts.

The projection position on the screen has shifted.

Video image suddenly goes out.

Lens shift adjustment is not possible.

Remote control unit does not work.

Probable cause

Has the lamp’s life come to its end?

While computer system signal is input, isn’t a sync signal for composite sync (Cs) or G on sync being input?

Isn’t signal with much jitter or skew distortion being input from a VCR?

Is sync signal being input correctly?

Has the projector been moved?

Isn’t video turned off by pressing the remote control unit’s HIDE button?

Are all video signals being input correctly?

Is the shift center lock pin for shipment left attached?

Are batteries installed correctly?

Are batteries exhausted?

Is there a shielding object between the remote control unit and the remote sensor?

Is the distance too long?

Is the remote control unit’s LOCKÔUNLOCK switch set to LOCK?

Corrective action

Check the lamp’s use hours on the menu, and if the lamp life is near its end, consult the dealer where you purchased the projector.

Input separate sync signals for vertical sync (V) and horizontal sync (H) signals.

Input signals with little jitter or distortion.

Check sync signal and related connection.

Check the installed position.

Press the remote control unit’s HIDE button to turn video on.

Check signals and connections.

Remove the shift center lock pin, and then make adjustments. (For how to remove the shift center lock pin, consult the dealer where you purchased the projector.)

Match the polarities of batteries correctly (+ to + and – to –).

Replace with new batteries.

Remove any shielding objects.

Use the remote control unit at a nearer point.

Set the remote control unit’s

LOCKÔUNLOCK switch to UNLOCK.
