8 ways to fix your NEC TV with no sound
There are several basic fixes to an NEC TV with no sound; here are a few checks.
Adjust TV volume settings
Check if the TV volume is set to zero or muted. Unmute your NEC TV if it’s muted.
Alternatively, increase the volume above zero by using the up and down buttons on your NEC TV remote.
Adjust the volume of the connected media device, like the streaming player and satellite box.
Unplug and reconnect the power cord
This is the easiest and most common way of fixing an NEC TV with no sound.
Unplug from the socket and wait for 1 minute before plugging back in. This clears any issue with interference from nearby electronic devices.
Ensure the cables are securely connected
If the cables connecting to your TV are secured connected, disconnect and reconnect again for best results.
Check to ensure the wires are in perfect condition, not frayed, and plug in securely.
Check external audio
Switch the external sound system, like the sound bar or surround sound, with the default speakers to test where the issue lies. If they produce sound, the external speakers are the problem. Get them fixed; if not, it’s the NEC TV.
Check the signal
The signal is the issue if the audio works with a different feed.
Check what is transmitting feed to your TV and switch to something different for testing. For instance, switch to WIFI or connect a PC and project to the TV if using a cable.
Perform a software update
Check if your NEC TV is running on the latest software version.
Software updates install automatically when your TV is connected to the internet. However, the process may sometimes get disrupted, making your NEC TV run on outdated software.
Resolve this issue by updating the software by connecting to reliable internet or manually via the settings option.
Steps for manual update include;
- Press the V key on your remote
- Click systems tab
- Check for updates in the drop-down menu
- The TV will look for updates, if any, and confirm the installation
- Restart the TV, and your problem is solved
Revert your NEC TV to factory setting if all the above hacks fail. This will erase all data eliminating any software problems.
- Select Settings on your TV remote
- Click system
- Click reset & Admin
- Select reset TV to factory setting
- Press OK and wait for the TV to turn off
Suppose you don’t have a remote; press and hold the power button for at least 10 seconds. This should turn off the TV, reboot it, and factory reset it.
Check for an active warranty
If the issue persists after trying the above fixes, contact NEC customer service.
Describe the problem, and the team will replace or repair the TV if it’s covered under an active warrant.
