Overview of model numbers and SW ID: Q554x_SW_ID.xls

INFO:
An upgrade of the Stand-by software is needed to counter issues like:
- Picture freezes.
- No response to remote control commands.
- TV set sometime switching off by itself and rebooting.
- Not able to change channels.

CURE:
Upgrade the Stand-by software of the TV to version 99.0.0.0 (or higher).
There are two upgrade methods: via USB stick or via Remote Service. See instructions below.

Before you start, ensure that you have the following:
• A USB flash drive (= stick) with at least 100MB of free space (note: do not use a USB hard disk drive for a software update).
• A file compression application (the latest version of WinZip® is recommended).
Note: This procedure assumes that you use a Microsoft® Windows® PC with the latest version of WinZip installed.

USB-stick
Step 1. First, check the Main TV software:
- Be sure to have the latest Main TV SW loaded: v0.96.0.0 (or higher). If okay, proceed with Step 2.
- If not okay, download the file from the Philips support website and follow the given instructions.
When ready, go to Step 2.

Step 2. Upgrade Stand-by software:
- The upgrade file is attached: select and download the "StandbySW_Q554x_99.0.0.0.zip" file (the "x" is model dependent: M is for M/08 sets, the rest uses E).
- Insert the empty USB flash drive into a USB connector on your PC.
- On your PC, create a folder named "upgrades’ in the root directory of the USB flash drive.
- Extract the UPG-file to the "upgrades" folder on the USB flash drive (do not place in the root dir).
- Using the archive utility, extract the UPG-file to the "upgrades" folder on the USB flash drive.
- Safely remove the USB flash drive from the PC.
- Remove all USB devices (such as Wi-Fi adaptor) from the TV, then switch ON the TV.
- Connect the USB flash drive to a USB connector on the TV.
- Press the Home/Menu button, and select [Setup] > [Software settings] > [Local updates].
- Select the correct UPG file and press OK.
- A prompt appears, select [Continue], then press OK.
- The software upgrade starts automatically.
- The upgrade is complete when a notification message appears on screen.
- Remove the USB flash drive from the TV.
- You need to disconnect the power cable from the power outlet. Wait one minute then reconnect it. After that you can start your TV in the usual way.
