How to synchronise video and sound of Philips TV?

Ensure that:

• The latest software has been installed

• The sound of the viewed media is timed correctly with the video. For example, use a recording checked on another device such as a PC, smartphone, laptop or another TV

1. Test with YouTube

Check if the audio and video are synchronised on other sources on the TV, for example on the YouTube App, or with a Blu-ray disc.

A restart resets the software buffer, which might help to synchronise the audio and video.

To perform a power cycle, proceed as follows:

• Switch the television OFF

• Unplug all cables and accessories from the television itself

• Wait for at least one minute before plugging all cables in again

• Switch the television ON again

Determine if the audio is too early or too late in relation to the video

If the audio is later than the video, proceed to scenario A .

If the audio is earlier than the video, proceed to scenario B .

Note: please note that not all TVs have the same functionality.
