Sony A90J No Sound

If you're experiencing Sony A90J no sound issues, you're not alone. Audio problems on this premium OLED television can stem from software glitches, incorrect settings, or hardware connections. This guide walks you through proven troubleshooting steps to restore audio on your Sony A90J, whether the problem affects all sources or just specific apps and inputs.

Quick Fixes for Sony A90J No Sound

Before diving into advanced troubleshooting, try these simple solutions that resolve most Sony A90J no sound cases:

Check the Volume and Mute Settings: Press the Volume Up button on your remote and verify the mute icon isn't displayed. Navigate to Settings → Sound → Volume to confirm the TV isn't set to minimum. Also check if headphones or Bluetooth audio devices are connected and redirecting sound away from the TV speakers.

Restart Your Sony A90J: Perform a full restart by holding the power button on the remote for 5 seconds until "Power off" appears, then select it. Wait 30 seconds, then turn the TV back on. This clears temporary software glitches that commonly cause audio failures.

Test Multiple Sources and Inputs: Switch between different inputs (HDMI 1, HDMI 2, built-in apps like Netflix or YouTube) to determine if the no sound issue is source-specific. If sound works on apps but not HDMI devices, the problem likely involves external equipment or port settings.

Verify Audio Output Settings: Go to Settings → Sound → Audio Output and ensure "TV Speakers" is selected if you want sound from the built-in speakers. If using a soundbar or receiver, confirm the correct output (ARC/eARC or Digital Audio Out) is active and properly configured.

Advanced Troubleshooting Steps

If basic steps don't resolve your Sony A90J no sound problem, proceed with these deeper fixes:

Update the TV Firmware: Navigate to Settings → System → About → System Software Update → Check for Updates. Sony regularly releases patches that fix audio bugs. Install any available updates and restart the TV afterward. Enabling "Automatically check for update" prevents future issues.

Reset Sound Settings to Default: Go to Settings → Sound → Reset to restore all audio configurations to factory defaults. This eliminates problematic custom settings that may be suppressing output. You'll need to reconfigure any personalized sound modes (Cinema, Sports, etc.) afterward.

Warning: A full factory reset will erase all your apps, login credentials, and personalized settings. Only perform this as a last resort via Settings → System → Reset → Factory Data Reset. Back up important configurations beforehand.

Frequently Asked Questions

Why does my Sony A90J have no sound only on HDMI inputs?

This usually indicates an HDMI-CEC or ARC/eARC configuration issue. Check that your connected device isn't set to output bitstream audio formats your TV can't decode. Try disabling eARC temporarily in Settings → Sound → Advanced settings → eARC mode, or switch the HDMI cable to a different port. Also verify the external device's audio output settings match your TV's capabilities.

Can a software update really fix no sound problems on the A90J?

Yes. Sony has released multiple firmware updates specifically addressing audio dropouts and no sound issues on the A90J. Version updates have resolved Bluetooth audio conflicts, eARC handshake failures, and built-in app muting bugs. Always keep your TV updated to the latest firmware available.

My Sony A90J sound cuts out intermittently. Is this the same issue?

Intermittent audio loss shares similar root causes with complete no sound failures but often points to specific triggers. Check for overheating (ensure ventilation around the TV), test without any audio accessories connected, and disable "Auto picture mode" which can sometimes conflict with sound processing. If cutting out occurs only with Dolby Atmos content, verify your audio chain supports Atmos passthrough.
