TU or N5200 model TV displays a USB error on the screen

The TV, smart monitor, or projector may display the following error messages, mode not supported, no signal or weak signal, check signal cable, no time information, locked, or the HDCP has been compromised. Instructions for correcting the conditions that cause the screen to display each of these error messages are available in this guide.

If you are connecting your HW-A40R to your TV via Bluetooth you may have experienced the sound intermittently cutting out. A simple software update to the sound bar will solve this issue and keep it from happening.

If your soundbar or subwoofer is making an abnormal or distorted sound, in most cases, it requires a firmware update, but checking connection cables can also solve the issue.

If you notice that your Q600A, A650, or T650 soundbar is out of sync with your TV or randomly disconnects when connected via HDMI ARC, there is a simple solution to correct this issue. 

If your soundbar sound drops out, or is not making sound while watching the TV source, there is an easy way to resolve the issue. Generally if you change the channel on your TV or Set Top Box the sound should come back, but to permanently fix the issue you can update the firmware on your soundbar.
