• Press the A/V Mute button on the remote control to resume video and audio if they were temporarily
stopped.
• Press the Source Search button to switch to the correct input source, if necessary.
• Check your computer or video source to make sure the volume is turned up and the audio output is set
for the correct source.
• Check the audio cable connections between the projector and your video source.
• Make sure any connected audio cables are labeled "No Resistance".
• If you are using the USB Display function, turn on the Output audio from the projector setting in the
Epson USB Display Settings program on your computer.
• If Standby Audio is enabled (PowerLite 935W), the projector's fans may be louder than usual when
the product wakes up from standby mode. The projector's fans should resume normal noise levels
within 2 minutes.
