Question about Sharp LC-42D64U 42 in. LCD HDTV
About once every 5-10 minutes my Sharp LC-42D64U will flash a blue box in the top right hand portion of the screen showing that it is switching between stereo and mono sound settings.
While the sound switch is barely noticable, the blue box constantly poping up in the top right is incredibly annoying.
I had the same problem.
All I did was unplug the standard cable wire from my tv and used RCA cables to connect my TV to my digital cable box the the Input 1 jack in the back. It also increased the video quality.
