Proper service and repair is important to the safe, reliable
operation of all Philips Consumer Electronics Company**
Equipment. The service procedures recommended by Philips
and described in this service manual are effective methods of
performing service operations. Some of these service
operations require the use of tools specially designed for the
purpose. The special tools should be used when and as
recommended.
It is important to note that this manual contains various
CAUTIONS and NOTICES which should be carefully read in
order to minimize the risk of personal injury to service
personnel. The possibility exists that improper service
methods may damage the equipment. It is also important to
understand that these CAUTIONS and NOTICES ARE NOT
EXHAUSTIVE. Philips could not possibly know, evaluate and
advise the service trade of all conceivable ways in which
service might be done or of the possible hazardous
consequences of each way. Consequently, Philips has not
undertaken any such broad evaluation. Accordingly , a
servicer who uses a service procedure or tool which is not
recommended by Philips must first satisfy himself thoroughly
that neither his safety nor the safe operation of the equipment
will be jeopardized by the service method selected.
* * Hereafter throughout this manual, Philips Consumer
Electronics Company will be referred to as Philips.
WARNING
Critical components having special safety characteristics are
identified with a by the Ref. No.in the parts list and
enclosed within a broken line*
(where several critical components are grouped in one
area) along with the safety symbol on the schematics or
exploded views.
Use of substitute replacement parts which do not have the
same specified safety characteristics may create shock, fire,
or other hazards.
Under no circumstances should the original design be
modified or altered without written permission from Philips.
Philips assumes no liability , express or implied, arising out of
any unauthorized modification of design.
Servicer assumes all liability .

Automatic Power Saving
If you have VESA / DPMS compliance display card or software
installed in your PC, the monitor can automatically reduce
power consumption when power saving function active. And if
an input from keyboard, mouse or other devices is detected,
the monitor will automatically wake up. The following table
shows the power consumption and signaling of this automatic
power saving feature:
This monitor must comply with the Microsoft On Now
specification, with two power management states, as defined
by the VESA DPMS document. And must appropriately display
the DPMS states. Also comply with Environmental Protection
Agency (EPA) Energy Star and TCO03 power management
standard strictly.
ENERGY STAR is a U.S. Registered mark. AS AN ENERGY
STAR PARTNER, PHILIPS HAS DETERMINED THAT THIS
PRODUCT MEETS THE ENERGY STAR GUIDELINES OF
ENERGY EFFICIENCY.
