Philips Tv No Sound

Having issues with no audio or low sound on your Philips TV? Don’t worry – you’re not alone. Sound problems are among the most common technical issues reported by Phillips TV owners. The good news is that most sound problems have simple solutions that you can fix yourself without an expert.

In this comprehensive guide, we’ll walk you through all the typical causes of Philips TV sound issues and provide step-by-step instructions to resolve them.

An Overview of Sound Issues on Philips TVs

Before jumping into troubleshooting, let’s quickly go through the most prevalent sound problems faced by Philips TV owners:

No sound – The most obvious issue where you get no audio at all from the TV speakers or connected external audio system. This points to a connectivity/settings issue.

Low volume – TV volume is simply too low even when volume settings are maxed out. Easy fix by tweaking audio configurations.

Muffled/muddy sound – Sound feels stuffy and lacks clarity. Usually a problem with the equalizer settings.

Intermittent sound – Sound works fine for a while but keeps cutting out randomly. Indicates loose cable connections.

Sound delay – You see the video but the matching audio comes in late, causing a lag. Caused by incorrect audio sync settings.

The troubleshooting steps outlined in the following sections will help you diagnose and resolve all the above problems. Let’s get onto it!

Step-by-Step Philips TV Sound Troubleshooting

Follow these steps sequentially to pinpoint and fix sound issues on your Philips TV:

1. Check Physical Connections

Loose or incorrectly connected cables account for a majority of Philips TV sound problems. For troubleshooting tips on additional issues like TV won’t turn on.

  • Inspect cables connecting TV with audio sources like set-top box, Blu-ray player, etc. Reconnect if loose.
  • If using external speakers/soundbar, check those physical connections as well.
  • While at it, also check that all connected devices are turned ON.
  • For Philips TVs with built-in Chromecast, check WiFi connection strength.

This simple check will solve most cases of no audio.

2. Verify Sound Settings

If connections are fine, access your TV’s sound settings menu to adjust configurations:

  • Navigate to Sound Menu > Speaker Settings and turn ON TV Speakers if disabled.
  • In Sound Menu > Volume Levels, turn up volume, check that Mute is disabled.
  • Under Sound Menu > Sound Style, try different presets like Movie, Music, Sports, etc.
  • Adjust equalizer under Sound Menu > Sound Mode Settings if sound feels muddy.

Cycling through the different audio presets is an easy fix for issues like muffled sound.

3. Check Source Input Audio

The problem may also lie with the connected audio/video source like a DTH box or media player.

  • If using a set-top box or Blu-ray player, check their audio settings. Turn up volume if too low.
  • Try playing content from a different source device to isolate the issue.
  • For antenna TV connection, rescan channels. For DTH connection, check RF cable.

This will clarify if the problem is with a particular source device or input method.

4. Reset Audio Settings

If tweaking settings doesn’t help, reset your Philips TV’s audio configurations:

  • Go to Support > Factory Settings option and select Reset Audio Settings.
  • This will revert all audio parameters back to their default factory values.
  • Post reset, make incremental audio adjustments starting with speaker volume.

Factory resetting audio eliminates any incorrect configurations that could be causing problems.

5. Update TV Software

Outdated TV software can also lead to audio glitches.

  • Navigate to Support > Software Update to check for pending updates.
  • If an update is available, download and install it.
  • This will upgrade the TV OS to the latest patched version.
  • After update, check if previously observed audio issues are now resolved.

Regular software updates often include critical bug fixes for common device issues.

6. Isolate Hardware Fault

In rare cases when software troubleshooting fails to fix sound problems on your Philips TV, it likely indicates a hardware malfunction:

  • Hardware issues can arise due to ageing TV components or physical damage.
  • Try connecting external speakers/headphones to TV audio output.
  • If same problem reproduces on external audio devices, TV hardware components like internal speakers or audio IC chip may be faulty.

Don’t attempt DIY repair of hardware issues. Call certified Philips TV technician for assistance.

Advanced Troubleshooting Tips

Let’s now go beyond basic troubleshooting to resolve tricky, intermittent sound problems on Philips TVs:

🔹 Enable Audio Passthrough – For media playback issues from streaming sticks/consoles connected via HDMI-ARC, enable passthrough in Sound Menu > Advanced > Audio Out Format. This will allow an uncompressed signal transfer without TV audio processing.

🔹 Change Audio Format – Switch between audio formats like Dolby Digital and PCM Stereo under Sound Menu > Advanced Settings if you face codec compatibility issues with your home theater receiver.

🔹 Adjust AV Synch – If audio noticeably lags behind video, access Support Menu > AV Synch Adjustment and tweak +/- settings till sync is correct. Useful for streaming/Bluetooth issues.

🔹 Test Individual Speakers – Navigate to Sound Menu > Speaker Settings > Speaker Test to check all internal speakers one-by-one for functionality if volume imbalance is noticed. Replace faulty speakers that emit no sound.

🔹 HDMI-CEC Troubleshooting – Intermittent sound when using HDMI-CEC compatible home theater? Under Support Menu > HDMI-CEC, disable System Audio Control and ARC features, then re-enable one by one to identify problematic setting.

Hopefully the advanced pointers will help resolve unique, case-specific sound problems on your Philips TV.

FAQs – Philips TV Sound Issues

Here are answers to some frequently asked questions related to troubleshooting audio problems on Philips TVs:

Q1. Why is my Philips TV sound intermittent?

A1. Loose HDMI or audio cable connections usually cause dropping audio. Securely reconnect cables. Faulty speakers can also trigger intermittent sound – get them checked by service technician.

Q2. How to improve muffled sound on my Philips Smart TV?

A2. Navigate to Sound Menu > Sound Style, change setting from Standard to Movie/Music/Sports to get clearer audio. Also adjust equalizer bands like 100 Hz, 300 Hz etc. under Sound Mode Settings.

Q3. Why is the volume too low on my new Philips Roku TV?

A3. Access Volume Levels setting under TV Sound Menu. Increase volume to max permissible limits. Check speakers under Speaker Settings are enabled. If volume still feels low, connected external audio equipment may have configuration issues.

Q4. How do I sync audio with video lag on my Philips Android TV?

A4. Too much lag indicates the ‘Audio Out’ mode is incorrectly set. Under TV Sound Menu > Advanced, change Audio Out Format from Bitstream to PCM Stereo. Still facing lag? Access Support Menu > AV Synch Adjustment > Audio Delay to sync sound.

Q5. Philips TV sound works on internal speakers but not on soundbar over ARC?

A5. This points to HDMI-ARC connectivity issues. Under Support Menu > HDMI-ARC, disable ARC feature and re-enable it. Also re-check physical HDMI cable connections between TV and soundbar.

Hopefully these common audio-related queries provide more context into the kind of sound problems you may encounter on your Philips TV.

When to Call a Technician

While a majority of the sound problems can be fixed by following the software troubleshooting steps outlined so far, it may be wise to call a certified Philips TV repair technician for assistance with complex hardware faults like:

  • Physical damage to internal TV speakers – possibly caused during transit or improper handling.
  • Burnt audio IC chip on main TV board – requires soldering replacement.
  • Power supply issues triggering sound cut-offs – needs diagnosis of backlight voltages.

Unless you have requisite skills and equipment, it is best left to professionals when hardware repair/replacement is needed. Locate an authorized Philips TV technician near you for cost-effective assistance.


I hope this detailed troubleshooting guide helped you get to the bottom of annoying sound problems on your Philips TV. We have covered a wide range of causes – from loose connections and incorrect settings to faulty hardware – along with matching solutions.

While tweaking configurations and running audio tests, be patient and make incremental changes to isolate the issue accurately. Don’t hesitate to reach out to the friendly Philips TV support team for more tailored troubleshooting tips specific to your model.

As a takeaway, make it a habit to periodically check your TV hardware health to identify and fix problems early. Keep your TV, external devices and connectors dust-free and properly ventilated to prevent overheating issues. And consider investing in a good surge protector – electrical spikes can damage those delicate audio components over time!

Here’s wishing you an immersive, cinematic viewing experience on your Philips TV without any pesky sound problems in the way!
