Now that you have a better idea of which fixes for the Philips TV we will try, let’s first examine the causes behind the sound issue.
Why Does My Philips Roku TV Have No Sound When Not Muted?
If you notice that your Philips Roku TV does not produce any sound or your sound devices connected to it don’t properly work, it’s likely due to an issue with the settings.
In rare cases, it could be due to a hardware issue with the speakers or your home audio system.
Here are some of the more common causes of Philips Roku TV having no sounds:
Now that you know about the biggest culprits for sound-related issues on your Philips Roku TV, let’s try out some fixes.
How to Troubleshoot Philips Roku TV Has No Sound But Not Muted
Tip: Check that the power strip where your TV is connected is not overloaded by other devices.
Solution #1: Restart Your Philips Roku TV
Philips Roku TV’s no sound can oftentimes be caused due to a runtime error with the TV software that glitches out the audio channels.
To fix this issue, power cycling can be used to clear any residual electricity on the circuit board.
Here are the steps to power cycle your PhilipsTV:
- Turn off your TV using the power button on your remote or the TV itself.
- Unplug the TV from the electrical outlet.
- Wait for about 60 seconds with the TV unplugged.
- Press and hold your Philips power button while it’s unplugged for half a minute.
- Replug the TV into the electrical outlet.
- Turn on the TV using the remote or the power button on the TV.
- Play a video to check if the sound issue is resolved.
Note: Your Philips Roku TV allows you to easily access streaming services, which might have their own volume control remote.
Solution #2: Check Audio Settings
The second most common reason why your Philips has no sound, even though it’s not on mute, is due to incorrect audio settings.
These settings can sometimes become overwritten and default to the wrong audio output.
Here is how to manually set the proper audio settings for your Roku device:
- Press the ‘Home’ button on your Philips TV remote to access the menu.
- Select ‘Settings‘ from the menu.
- Navigate to and select ‘Audio‘ settings.
- Try switching the audio output by ensuring the Audio Mode is set to ‘Stereo’ or ‘Auto.’
- Disable ‘Leveling‘ or ‘Night‘ modes in Volume Mode if they are enabled.
- Play a video to see if the sound issue is fixed.
If adjusting the settings doesn’t work, try switching to a different audio output, such as an external speaker or headphones.
Note: Your Philips TV should support most multimedia formats like AAC, AC3, or MP3 through USB playback.
Solution #3: Update Philips TV Software
If your Philips Roku TV is running on old or non-updated software, it can run into issues such as incorrect audio output.
To prevent this instance from affecting your Roku TV, you have to manually check for pending updates.
Here is how to check your Philips for outdated software and install new updates:
- Press ‘Home‘ on the remote to go to the Home Screen.
- Note, based on your TV model, these steps might vary, so check with the TV manual if you are unsure.
- Find and select ‘Settings‘ by using your Philips or Roku TV remote.
- Navigate to and select ‘System‘.
- Choose ‘System Update‘ and update the software if available.
- Restart the TV after the update.
- Check the sound by playing a video.
Afterwards, test different streaming channels or inputs to ensure the sound issue isn’t isolated to a specific source.
Note: If you have trouble installing the updates through a WiFi network, they can be installed through a USB flash drive.
Solution #4: Check External Devices
Sometimes, the external devices you use for audio playback or multimedia use can cause sound issues due to incompatibility or wrong settings.
To ensure this isn’t affecting your Roku TV, you have to verify that your external devices are in working order.
Here are the steps on how to check your external devices connected to your Philips TV:
- Ensure all cables connected to your TV are secure.
- Try using a different HDMI or audio cable, as it might be causing no sound issues.
- Turn off any connected devices like soundbars or consoles.
- Reconnect the cables after disconnecting them.
- Turn on the connected devices and check if they are the cause of the sound issue.
- Select the correct input source on your Roku TV.
- Play something to test the sound.
If the issue persists, test your external devices with another TV or audio output to rule out device-specific issues.
Note: Check if your TV is in listening mode, as some voice-activated Philips TVs can use assistants like Alexa.
Solution #5: Reset Audio/Video Settings
A surefire way to fix most audio issues is to restore them to the default values.
This can have a two-fold effect – one, clear up potential configuration issues, and two – fix compatibility issues.
Here are the general ways to reset and reconfigure your Philips audio settings:
- Use the remote to open the primary menu of your TV.
- Select ‘Settings‘.
- Choose ‘System‘ from the menu.
- Find and select ‘Advanced System Settings‘.
- Choose ‘Reset audio/video settings.’
- Confirm the reset and then check the sound.
When you are ready with the steps above, play content from different sources to check if the audio problem is consistent across all inputs.
Note: You can try to clear your audio settings from the Roku App on some Philips TVs.
Solution #6: Factory Reset TV
A factory reset is often the last tool in your kit when troubleshooting a Roku TV device, as it deletes any saved settings, user profiles, and such when performed.
The reason for a factory reset is that it can fix some hidden settings or parameters that prevent audio playback.
Here are the steps on how to perform a factory or hard reset for your Philips TV:
- Press ‘Home‘ and go to ‘Settings‘ to access the Settings Menu.
- Navigate to and select ‘System‘.
- Choose ‘Advanced’ or ‘System Settings‘.
- From the menu, pick the option ‘Factory Reset,’ then check for any code and enter it as shown on the screen.
- Confirm the action to reset the TV.
- Complete the initial setup and test the sound.
After these steps, check for any available software updates post-reset, as these might not be applied automatically.
Note: Ensure your Roku TV has a solid WiFi connection so it can automatically download and install any updates.
Solution #7: Check Devices and Remotes for Mute Functions
If you have successfully reset your Roku TV but still face a sound issue, perhaps the fault is within a mute function being turned on.
While you might not be muting your Philips TV from the remote, there could be a mute function on your audio playback devices instead.
Here is how to check your Roku TV and sound devices for hidden mute functions:
- Ensure the mute button isn’t stuck on the remote.
- Check if there’s a plug in the headphone jack of the TV.
- Remove any headphones if they are plugged in.
- Check if individual channels or apps are muted.
- Adjust the volume to a higher level.
- Play a video to test the audio.
- Try adjusting the audio sync settings in case there’s a delay causing the sound to seem absent.
If the steps above didn’t resolve your issue, inquire about warranty coverage or recommended service options.
Note: Some audio speakers or soundbars might have a mute toggle - check that as well.
To fix the Philips Roku TV has no sound but is not muted, start by resetting your TV and going through its audio settings.
Next, check if the issue is not with your audio devices instead.
