  If the remote control for your Sharp Home Theater System isn't working correctly, first check that the batteries are inserted with the correct polarity. If they are, try replacing the batteries. Ensure that there are no obstructions between the remote and the sound bar, and that you are within the correct distance and angle. Also, strong light shining on the remote sensor or another remote sensor being used simultaneously can interfere with the signal. Try eliminating strong light sources and ensuring only one remote sensor is in use.

  If your Sharp Home Theater System isn't detecting your device or playback won't start, make sure the device contains MP3/WAV/FLAC files. Ensure the device is properly plugged in and that it is not an MTP device. If the device only contains AAC files, use a device with MP3/WAV/FLAC files. Also, check that a false MP3/WAV/FLAC file is not being played back.
