The Sharp LC-20B5M may enter a mode where the screen shuts off while the sound continues. This happens when the BRIGHT key on the remote control is pressed, setting "BRIGHTNESS [OFF]". In this mode, only the on-screen display (OSD) appears, but channels and volume can still be adjusted. To exit this mode, press the BRIGHT key again and select any brightness setting other than "OFF".
