Why is there no sound coming out of the screen's speakers?

Make sure the volume is turned up to a high volume (50% to 75%). Check to see if the volume is raised to a proper level by pressing the volume buttons (the + and - buttons at the bottom right side on the front of the monitor). If the volume buttons on the monitor are not responding, please refer to the replacement guide and purchase new buttons. If all of the above do not apply to your situation, please refer to the speaker replacement guide and purchase new speakers.
