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).

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.
