Hi, we bought our son a used 2005 Golden Tee at auction for his game room. all of a sudden the monitor seems to have lost all color except what appears to be blue and black. the picture and sound are there, but the picture is a strange color. what I see seems to be blue and black and no other colors. has anyone seen anything like this before? could it be something simple like a bad connection? something dirty? or is this something expensive? thank you all for any help. and if I have posted in the wrong place please let me know.
