Purple haze/tint RCA big screen HDMI, how to fix?

Ok so i have a RCA HD56W58 hdtv big screen, i have not had any problems with it until a couple of days ago i turned on the tv and everything has a purple tint/haze like as if you were tearing at it through purple gles. but it is just when i choose my HDMI as the source everything ells looks fine composite 1, 2, 3 ,4 and front inputs look good its just the HDMI. Does anyone know how to fix this?
