If your TV is connected to the internet you should be able to update it via the TV menu. Keep in mind that not all TVs have updatable software.

So, if you cannot proceed to update through the menu, you can always connect the dedicated customer service to find out if an update is possible.

If you experience a sound delay on your TV channel and occasionally have audio and video out of sync on TV that you noticed recently, try changing it to another program to see if the same error still occurs.

If the issue appears on all other channels this is a clear sign that the issue is local.
