This may be random, but I experienced random shut downs during singers, skipping background music, and lyric screen not refreshing on my display (singer's display worked fine.) I discovered all my problems were resolved by running my HDMI through a splitter. I was able to reproduce the problems by connecting HDMI directly from laptop to TV and resolve them by using a splitter. I have no idea why it works, but it does.
