For TVs with only one button, press and hold the power button on the TV itself while plugging the power cord back in, continuing to hold until a white LED light appears (usually within 10-30 seconds).

Step #2: Check Audio Settings

Sony TVs offer various audio settings that can be adjusted to resolve sound issues. Here's a quick guide to checking and adjusting these settings:

Setting	Action
Volume	Ensure TV and connected devices are not muted or set to low volume
Audio Output	Verify correct audio output is selected (TV speakers, sound system, etc.)
Sound Mode	Try different sound modes (Standard, Cinema, Music)
Equalizer	Adjust bass, treble, and balance settings
Digital Audio Out	Check if set to PCM for compatibility with all devices
Audio Description	Disable if unintentionally activated

If audio issues persist after adjusting these settings, check all cable connections between the TV and external audio devices. Ensure HDMI or optical cables are securely plugged in and try different ports if available.

For smart TVs, check if the issue occurs in all apps or just specific ones, as this can indicate whether the problem is with the TV hardware or a particular streaming service.

When troubleshooting Sony TV issues, it's important to approach the problem systematically. If the steps outlined in this guide don't resolve your audio problem, remember that Sony provides comprehensive support resources. Visit Sony's official support website to access model-specific troubleshooting guides, firmware updates, and contact information for customer service

. For complex issues or potential hardware failures, professional servicing may be necessary. Always ensure your TV's software is up-to-date and consider the warranty status before seeking repairs

However, for persistent issues that affect theatrical sound quality, such as a lack of dynamic sound or issues with sound louder settings, reaching out to Sony's expert technicians is advisable. They can help maintain your TV's optimal performance and longevity, ensuring features like virtual surround sound processing and MTS (Multi-Channel Television Sound) remain effective. For more complex audio concerns, such as achieving a balanced sound with a connected third-party sound bar or adjusting the subwoofer sound for a brighter effect, expert assistance may be necessary. Sony's technicians can guide you through setting up external sound modes, selecting the right preset sound modes, and ensuring your surround sound mode or untouched sound settings are correctly configured. This professional support can help you achieve an awesome sound experience, even with complicated sound setups.
