Article: Many people have recently reported various issues with their audio-visual electronics, the most common ones being insensitive volume adjustment, abnormal display, and power button malfunction. These problems may arise from prolonged use or improper operation. To help address these issues, we will provide some solutions below.
Firstly, if the volume adjustment on your audio-visual device is insensitive, we recommend checking if the batteries in the remote control are low, or if the buttons on the remote control are dusty and affecting responsiveness. Additionally, check if the device is on mute or if the volume settings are incorrect.
