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.
