Philips Smart TV No Sound — Fix Guide

What Does This Error Mean?

A Philips Smart TV with no sound is most often set to mute or has its audio output routed to an external device (soundbar or ARC/eARC) that is off. Press the Mute button on the remote to check, then go to Settings > Sound > Audio output and confirm it is set to TV Speakers.

Affected Models

  • Philips 4K UHD Series
  • Philips OLED Series
  • Philips The One Series
  • Philips Ambilight TV Series

Common Causes

  • TV is muted
  • Audio output is set to HDMI ARC or optical — external speakers are off or disconnected
  • App-specific audio fault — audio works in other apps
  • Software crash affecting the audio stack

How to Fix It

  1. Press the Mute button on the remote. Check that the volume bar appears on screen and is not at zero.

  2. Go to Settings > Sound > Audio output. If it is set to HDMI ARC, Optical, or Bluetooth, change it to TV Speakers and test.

    If you have a soundbar connected via HDMI ARC, the TV routes audio to it automatically. If the soundbar is off or the cable is unplugged, the TV produces no sound.

  3. If sound is missing only in one app (e.g. Netflix but not YouTube), close and reopen the app. If the issue persists, clear the app's cache: Settings > Apps > [App name] > Clear cache.

  4. Perform a soft reset by holding the power button on the TV for 10 seconds. A software crash affecting the audio renderer is cleared by a hard restart.

  5. If no sound appears on any source or app after all of the above, go to Settings > TV Settings > Factory Reset to restore default audio settings.

    A factory reset erases your apps and settings — note down your WiFi password and any custom picture or sound profiles before proceeding.

Frequently Asked Questions

My Philips TV has sound on broadcast TV but not on HDMI — why?

HDMI audio requires the connected device to send an audio signal. Check that the source device (game console, Blu-ray player, streaming box) is not muted and that its audio output is set to HDMI. Also try a different HDMI cable — HDMI cable faults often affect audio before video.
