- To have a reliable operation of the EEFL backlight, the backlight should be driven with a maximum PWM duty
cycle during the first seconds. Only after this first one or two seconds, the PWM may be set to the requir ed output

the picture should only be unblanked after these first seconds.

is working) and all repair information is directly available.
4. ComPair features TV software up possibilities.
Specifications
ComPair consists of a Windows based fault finding program
and an interface box between PC and the (defective) product.
The ComPair II interface box is connected to the PC via an
USB cable. For the TV chassis, the ComPair interface box and
the TV communicate via a bi-directional cable via the service
connector(s).
The ComPair fault finding program is able to determine the

How to Connect
This is described in the chassis fault finding database in

ComPair.
Caution: It is compulsory to connect the TV to the PC as
shown in the picture above (with the ComPair interface in
between), as the ComPair interface acts as a level shifter. If
one connects the TV directly to the PC (via UART), ICs can be
blown!
How to Order
ComPair II order codes:
• ComPair II interface: 3122 785 91020.
(using 3.5 mm Mini Jack connector): 3138 188 75051.
• Software is available via the Philips Service web portal.

There are several mechanisms of error detection:

• Via polling on I/O pins going to the stand-by processor.
• Via sensing of analog values on the stand-by processor or
• Via a “not acknowledge” of an I
Take notice that some errors need several minutes before they

needs to be measured, no protection triggered here.
There are several types of software related protections, solving
a variety of fault conditions:
• Related to supplies: presence of the +5V, +3V3 and 1V2
• Protections related to breakdown of the safety check
mechanism. E.g. since the protection detections are done
by means of software, failing of the software will have to
initiate a protection mode since safety cannot be
guaranteed any more.
Remark on the Supply Errors
The detection of a supply dip or supply loss during the normal
playing of the set does not lead to a protection, but to a cold
reboot of the set. If the supply is still missing after the reboot,
the TV will go to protection.
Protections during Start-up
During TV start-up, some voltages and IC observers are
actively monitored to be able to optimize the start-up speed,
and to assure good operation of all components. If these
monitors do not respond in a defined way, this indicates a
malfunction of the system and leads to a protection. As the
observers are only used during start-up, they are described in
the start-up flow in detail (see section “5.3 Stepwise Start-up
The only real hardware protection in this chassis appears in
case of an audio problem e.g. DC voltage on the speakers. This
protection will only affect the Class D audio amplifier (item
