So I felt the screen on my jvc kwv 960bt was too bright. It’s predecessor had black and white adjustment which enabled one to dim the screen. I am one who appreciated this. The 960 after addressing reviewers complaints of too dim in direct sunlight this feature is no longer available. So I got some 35% reduction tint and put that on the screen. I did use windex as a lube before squeegeeing w my cc. Now the lower right hand corner is unresponsive. Hence my problem. I imagine some got in the body of the radio frame. It does work and sounds the same. Any idea’s other than investigating the possibility of ordering a new screen or sending the whole unit in to jvc?
