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
- Copy '"AUTORUN.UPG" to the root of the USB stick.
- 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.
