17 TROUBLESHOOTING GUIDE

Problems Solutions

No power: - Check the power switch at the rear: it must be in position I.

Green and red LED are OFF

- 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. 8)

- 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.

- If you are using the Remote Input Interface, do not to

confuse the menu for selection of projector’s inputs

(Source Selection), with the menu for selection of re-

mote inputs (Source Selection / RI2).

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

performance. Ensure the VCR mode is active in the

Picture menu.
