5.8.13 SSB Replacement
Follow the instructions in the flowchart in case a SSB has to be
exchanged. See figure "SSB replacement flowchart".
Before starting:
- prepare a USB memory stick with the latest software
- download the latest Main Software (Fus)
- unzip this file
- create a folder "upgrades" in the root of a USB stick (size > 50 MB) and
save the autorun.upg file in this "upgrades" folder.
Note: it is possible to rename this file, e.g."S54x_SW_version.upg"; this in
case there are more than one "autorun.upg" files on the USB stick.
Due to a possible wrong display option code in the received Service
SSB (NVM), it's possible that no picture is displayed. Due to this
the download application will not be shown either. This tree enables you
to load the main software step-by-step via the UART logging on the PC
(this for visual feedback).
1) Start up the TV set, equiped with the Service SSB,
and enable the UART logging on the PC.
2) The TV set will start-up automatically in the
download application if main TV software is not loaded.
3) Plug the prepared USB stick into the TV set. Follow the
instructions in the UART log file, press "Right" cursor key to enter
the list. Navigate to the "autorun.upg" file in the UART logging
printout via the cursor keys on the remote control. When the
correct file is selected, press
4) Press "Down" cursor and "Ok" to start flashing the main
TV software. Printouts like: "L: 1-100%, V: 1-100% and
P: 1-100%" should be visible now in the UART logging.
5) Wait until the message "Operation successful !" is logged in
the UART log and remove all inserted media. Restart the TV set.

Attention point for Net TV: If the set type and serial number are not
