Why is my Vizio M51a-H6 remote not working?
If the remote for your Vizio Speaker System isn’t working, try replacing the batteries with new ones. Ensure you are pointing the remote directly at the center of the sound bar when pressing a button.
What to do if my Vizio Speaker System has no sound?
If your Vizio Speaker System has no sound, first increase the volume by pressing the VOLUME UP button on the remote or the sound bar itself. Also, ensure that the sound bar isn't muted by pressing the MUTE button on the remote. Try selecting different input source by pressing INPUT on the remote or on the top of the sound bar. When using the Digital Optical input, try setting the TV output to PCM or connect directly to your Blu-ray or another source, as some TVs might not pass through digital audio. For digital inputs, if the input LEDs flash rapidly, set the source to output PCM. Check that your TV audio output setting is set to FIXED or STANDARD, not VARIABLE. If you're using Bluetooth, make sure the volume on your source device is turned up and that the device isn't muted.
How to troubleshoot a Vizio M51a-H6 Speaker System that has no power?
If your Vizio Speaker System has no power, begin by pressing the POWER button on the remote or on the sound bar itself. Then, make sure the power cord is securely connected. Finally, plug a different device into the electrical outlet to confirm that the outlet is working correctly.
How to fix buzzing or humming sound on Vizio Speaker System?
If you hear buzzing or humming from your Vizio Speaker System, make sure all cables and wires are securely connected. You can also connect a different source device (TV, Blu-ray player, etc.) to see if the buzzing persists; if it doesn’t, the problem may be with the original device. Also, try connecting your device to a different input on the sound bar.
