How to troubleshoot an LG M2241A with picture but no sound?
If you have a picture but no sound on your LG Monitor, begin by pressing the VOL + or - button to adjust the volume. Check if the sound is muted by pressing the MUTE button. Try switching to another channel to rule out a broadcast issue. Finally, ensure that the audio cables are correctly installed.
Why does my LG Monitor power off suddenly?
If your LG Monitor is suddenly turning off, check if the sleep timer is enabled and review the power control settings. Note that the monitor will automatically switch off after 15 minutes without an input signal to conserve power. Also, if playing a corrupted file in USB mode, the monitor might turn off; verify the file on your USB storage device.
