Preparation

Check the firmware version

Your firmware may already be up to date, especially if you have a new Home Theater System. If the version number is 1.279 or higher, you do not need to update.

If you're not sure, it's easy to check which version of firmware you have:

  1. Turn on your TV and make sure that it's tuned to the input your Home Theater System is connected to, so if the Home Theater System is connected to the HDMI2 socket, choose HDMI2 as the input.
  2. Turn on the Home Theater System.
  3. Press HOME on the remote control and wait until you see the HOME screen
  4. On the home screen, select SetupAdvanced Settings with the arrow keys on the remote control and then press ENTER.
  5. Select System SettingsSystem Information with the arrow keys on the remote control and then press ENTER.
  6. On the TV screen, if the version number is 001.279 or higher (the 1st and 2nd zeros of the software version number can be ignored), you already have the most recent firmware version.

Important Notice

  • Read the instructions carefully or you may damage your HT-A9.
  • Do not turn off the HT-A9 or disconnect it from AC power while it is updating.
  • Do not press any buttons, except the ones mentioned in the instructions.
  • Do not pull out the power cord or network (LAN) cable while the software is downloading and updating. It may cause the system to fail.

  • After the Update via Internet procedure has started, the message Download capacity: xxxxxxKB/xxxxxKB and xx% is display in TV screen is displayed but the progress bar on the display has not changed.
    Depending on the network connection, the Update via Internet procedure can take a long time (up to 60 minutes). That is why the message Download capacity: xxxxxxKB/xxxxxKB and xx% is display in TV screen is displayed and the progress bar on the display will not change for a long time.
  • When running the Update via Internet procedure, the TV displays the message, Connection status cannot be confirmed. Cannot communicate with the server. Please try again later. and you cannot perform the firmware upgrade.
    1. Make sure the LAN cable is connected.
    2. Make sure you have confirmed whether or not your Home Theater System has its own IP address in the network settings. (If you use a proxy server, type the IP address of the proxy you use into the Proxy Server field instead of the proxy hostname.)
    3. Try the update again.
  • The power went off while the update was in progress.
    Turn the Home Theater System on and try the update again.
  • The update has been going on for over 60 minutes and hasn't finished.
    If the Home Theater System is connected to the network wirelessly, connect to the network with a cable and try the procedure again.
    If the problem continues, the network transmission speed may be low. In that case, please try to update your system following the Update via USB Memory procedure.
  • The message Already Updated is displayed on the TV screen.
    The firmware version currently installed on the Home Theater System is the latest version
