ComPair
Introduction
ComPair (Computer Aided Repair) is a Service tool for Philips
Consumer Electronics products. and offers the following:
1.
ComPair helps to quickly get an understanding on how to
repair the chassis in a short and effective way.
2.
ComPair allows very detailed diagnostics and is therefore
capable of accurately indicating problem areas. No
knowledge on I
2
C or UART commands is necessary,
because ComPair takes care of this.
3.
ComPair speeds up the repair time since it can
automatically communicate with the chassis (when the
micro processor 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
problem of the defective television, by a combination of
automatic diagnostics and an interactive question/answer
procedure.
How to Connect
This is described in the chassis fault finding database in
ComPair.
Figure 5-2 ComPair II interface connection
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.
•
Software is available via the Philips Service web portal.
•
ComPair UART interface cable for TPM9.1x xx.
(using DB9 to 2mm pitch JST connector): 3122 785 90630.
Note:
When you encounter problems, contact your local
support desk.

Software Upgrading
5.5.1
Introduction
The set software and security keys are stored in a
NAND-Flash, which is connected to the PNX855xx.
It is possible
for the user
to upgrade the
main
software via the
USB port. This allows replacement of a software image in a
stand alone set, without the need of an E-JTAG debugger. A
description on how to upgrade the main software can be found
in the electronic User Manual.
Important:
When the NAND-Flash must be replaced, a new
SSB must be ordered, due to the presence of the security keys!
(CI +, MAC address...).
Perform the following actions after SSB replacement:
1.
Set the correct option codes (see sticker inside the TV).
2.
Update the TV software => see the eUM (electronic User
Manual) for instructions.
3.
Perform the alignments as described in chapter 6 (section
4.
Check in CSM if the CI + key, MAC address... are valid.
For the correct order number of a new SSB, always refer to the
Spare Parts list!

Main Software Upgrade
•
The “UpgradeAll.upg” file is only used in the factory.
Automatic Software Upgrade
In “normal” conditions, so when there is no major problem with
the TV, the main software and the default software upgrade
application can be upgraded with the “AUTORUN.UPG”
(FUS part of the one-zip file: e.g. 3104 337 05661 _FUS
_Q555X_ x.x.x.x_prod.zip). This can also be done by the
consumers themselves, but they will have to get their software
from the commercial Philips website or via the Software Update
Assistant in the user menu (see eUM). The “autorun.upg” file
must be placed in the root of the USB stick.
How to upgrade:
1.
Copy “AUTORUN.UPG” to the root of the USB stick.
2.
Insert USB stick in the set while the set is operational. The
set will restart and the upgrading will start automatically. As
soon as the programming is finished, a message is shown
to remove the USB stick and restart the set.
Manual Software Upgrade
In case that the software upgrade application does not start
automatically, it can also be started manually.
How to start the software upgrade application manually:
1.
Disconnect the TV from the Mains/AC Power.
2.
Press the “OK” button on a Philips TV remote control or a
Philips DVD RC-6 remote control (it is also possible to use
a TV remote in “DVD” mode). Keep the “OK” button
pressed while reconnecting the TV to the Mains/AC Power.
3.
The software upgrade application will start.
Attention!
In case the download application has been started
manually
,
the “autorun.upg” will maybe not be recognized.
What to do in this case:
1.
Create a directory “UPGRADES” on the USB stick.
2.
Rename the “autorun.upg” to something else, e.g. to
“software.upg”. Do not use long or complicated names,
keep it simple. Make sure that “AUTORUN.UPG” is no
longer present in the root of the USB stick.
3.
Copy the renamed “upg” file into this directory.
4.
Insert USB stick into the TV.
5.
The renamed “upg” file will be visible and selectable in the
upgrade application.
