MAINTENANCE AND TROUBLESHOOTING
MAINTENANCE AND CLEANING
The units in the system do not require internal adjustments
and do not contain any user-serviceable parts.
For replacement of the lamp or any other service requirements
seek qualified technical assistance from your nearest Dealer.
A soft cloth is normally sufficient for cleaning the DigiOptical
Image Processor or the Display. Use a slightly moistened cloth
to remove more stubborn dirt. In this case, before proceeding
switch off and disconnect the unit, and ensure that no liquid
penetrates to the inside.
TROUBLESHOOTING GUIDE
No power (LEDs always OFF)
•
Check that the units’ power switches are set to I.
•
Check that the power cables are correctly connected to the
units’ power sockets.
•
Check the condition of the fuse located on the power socket
on the rear of the Display.
•
Replace the fuse located on the display power socket with
an identical type (T 3.15A H).
•
If the fuse blows repeatedly, seek technical assistance from
your nearest Dealer.
Lamp fails to switch on
•
Allow a few minutes between switching off and switching on
again. This will allow the lamp to cool down sufficiently.
•
If the lamp fails to illuminate - even though the unit has had
time to cool down - seek technical assistance from your
nearest Dealer.
•
Check the state of the connection by interpreting the code
displayed by the system LEDs in accordance with Table 3.

If the problem occurs on a terrestrial broadcast source signal,
check that the receiver has been correctly tuned in and that
the aerial system is in good working order.
