I just installed my screen about three days ago and everything was working great. After about 5 minutes of using the screen today, it began to make a blueish type background. I dont really know how to describe it other than when I try to play a movie, parts of the screen such as character outlines are a blue or cyan. The blueish tint also appears to be wavy. I have a 7 inch in dash tft lcd hooked up through a s-video convertor to a composite connection on the screen. Any help is greatly appreciated
