9 CLEANING AND MAINTENANCE

The Projector and DigiOptic™ Image Processor do not require internal cleaning. There are no user serviceable parts inside the projector. Please refer all service requirements to qualified personnel.

Cleaning the projector’s cover:

Use a soft slightly damp cloth. Do not use abrasive cleaners, solvents or other harsh chemicals, as this will damage the finish of the cover. Avoid direct cleaning of the rear panel’s screen- printing.

Cleaning the lens:

The lens may be cleaned with a very soft, non-abrasive small brush, in order to remove dust particles. Alternatively, use a soft dry cleaning cloth (of the type used for camera lens cleaning) to remove fingerprints and grease marks.

10 TROUBLESHOOTING GUIDE

No power (Green and red LED are OFF)

-Check the power switch at the rear: it must be in position I.

-Check if the power cable has been connected correctly to a working socket.

-Check the power socket fuse, at the rear of the projector.

-Replace the fuse on the mains socket with an identical type (T 3.15A H) (Fig. 2).

-Should the problem persist, seek authorised technical assistance.

The lamp is not coming on

-Allow a few minutes pause between switching off and turning on again (from stand-by). This will allow the lamp to cool down sufficiently.

-If the lamp doesn’t come on – even though the projector has had sufficient time to cool down – seek technical assistance from your nearest Dealer.

No image

-Check that the selected input is actually connected to a active video or graphic signal.

-Check that the above source actually works.

-Verify compatibility of video/graphic signals with the technical specifications of the projector.

-Check the integrity of cables used to connect various sources.

-Check the cooling air inlets or air outlets on the units are not obstructed and the room temperature is below 35°C (95°F).

Image is disturbed, unstable or noisy

-Verify compatibility of video/graphic signals with the technical specifications of the projector.

-Check the integrity of cables connecting projector to various sources.

-If the signal source is a terrestrial broadcast (via a VCR) check that the receiving channel has been correctly tuned in and that the aerial system is in good working order.

-Should the problem be present with a signal coming from a video-recorder, ensure that the videotape is an Original “first generation” copy and in good condition.

-Adjust the VCR’s tracking control for optimum picture perfor- mance. Ensure the VCR mode is active in the Picture menu.

Incomplete image along borders (vertical and horizontal)
