5.9.6 Display option code
Caution: In case you have replaced the SSB, always check the
display option code in SAM, even if you have picture. With a
wrong display option code it is possible that you have picture,
but that in certain conditions you have unwanted side-effects.
5.9.7 Upgrade EDID NVM
To upgrade the EDID NVM you must short circuit pin 7 of the
EDID NVM to ground. Therefore some test points (EDID1 and
EDID2) are foreseen near the HDMI connectors, see ComPair
for further instructions.

5.10 Software Upgrading

5.10.1 Introduction
The set software and security keys are stored in a NAND-
Flash, which is connected to the PNX85xx via the PCI bus.

• The above overview of the NAND Flash shows the content
of the different partitions. It also shows which part of the
one-zip file erases and programs which part of the NAND
Flash.
• Remark: the above does not mean that you can reprogram
your HDMI keys with the "UpgradeAll.upg" file from the one
zip file. This can only be done in a secure environment (e.g.
the factory).
• The "UpgradeAll.upg" file is only used in the factory.
• The "FlashUtils.upg" file is only used by service centers
which are allowed to do component level repair on the
SSB.
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 03801 _FUS _Q582E_
0.37.0.0_commercial.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 DFU). The "autorun.upg" file
must be placed in the root of your USB stick.
How to upgrade:
1. Copy "AUTORUN.UPG" to the root of your USB stick.
2. Insert USB stick in the side I/O while the set is in ON
MODE. The set will restart and the upgrading will start
automatically. As soon as the programming is finished, you
will get the message that you can remove your USB stick
and restart the set.
Manual Software Upgrade
In case that the software upgrade application does not start
automatically, you can also start it manually.
How to start the software upgrade application manually:
1. Disconnect the TV from the Mains/AC Power.

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 DFU.
Important: When the NAND-Flash must be replaced, a new
SSB must be ordered, due to the presence of the security
keys!!! (copy protection keys, 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 DFU for instructions).
3. Perform the alignments as described in chapter 8 (section
"Reset of Repaired SSB").
4. Check in CSM if the HDMI keys are valid.
The software image resides in the NAND-Flash, and is
formatted in the following way, see table 5-3 NAND-Flash
content.

2. Press the "OK" button on a Philips DVD RC-6 remote
control (it is also possible to use the 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 that you have started the download application
manually, the "autorun.upg" will maybe not be recognized.
What to do in this case:
1. Create a directory "UPGRADES" on your 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 your USB stick.
3. Copy the renamed "upg" file into this directory.
4. Insert USB stick in the side I/O.
5. The renamed "upg" file will be visible and selectable in the
upgrade application.
Back-up Software Upgrade Application
If the default software upgrade application does not start (could
be due to a corrupted boot 2 sector) via the above described
method, you can try to activate the "back-up software upgrade
application".
How to start the "back-up software upgrade application"
manually:
1. Disconnect the TV from the Mains/AC Power.
2. Press the "CURSOR DOWN" button on a Philips DVD RC-
6 remote control (it is also possible to use the TV remote in
"DVD" mode). Keep the "cursor down" button pressed
while reconnecting the TV to the Mains/AC Power.
3. The software upgrade application will start.
