PHILIPS - 37PFL 5603D_ SOFTWARE UPGRADE



UPGRADE 'EDID' NVM

In case the SSB have been replaced, always check the display option code in SAM, even if there is picture.  With a wrong option code it is possible there will be a picture, but that in certain conditions will have unwanted side-effects.

EDID NVM Upgrade

To upgrade EDID NVM, short circuit [pin-7] of the EDID NVM to Ground.  Therefore, some test points [EDID1, EDID2 & EDID3] are foreseen next to the HDMI connectors.  See the figure.


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

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 can be found in the DFU.

PERFORM THE FOLLOWING ACTIONS AFTER 'SSB' REPLACEMENT

  1. Set the correct Option Codes. [See the sticker inside the TV]
  2. Upgrade TV software.
  3. Perform alignments.
  4. Check in CSM if HDMI keys are valid.

Automatic Software Upgrade

In normal conditions, so when there is no major problem with the TV, the main software and default software upgrade application can be upgraded with the 'AUTORUN.UPG' (FUS part of the one-zip file).  This can also be done by the customers themselves, but they will have to get the software from commercial Philips website or via the Software Upgrade Assistant in the user menu. The 'autorun.upg' file must be placed in the root of the USB stick.  

UPGRADE PROCEDURE
  1. Copy '"AUTORUN.UPG" to the root of the USB stick.
  2. Insert USB stick in the side I/O, while the set is ON.  The set will restart and upgrading will start automatically.  As soon as the programming has been finished, will get the message that the USB stick can remove and to restart the set. 
MANUAL SOFTWARE UPGRADE
  • Disconnect the TV from Mains AC Power.
  • Press the 'OK' button on a Philips DVD RC-6 remote control.  Keep the 'OK'  button pressed while reconnecting the TV to the Mains AC power.
  • The software upgrade application will start.
