How can i fix Conia tv model CLCD2638DHD?

My LCD has a problem with its Color and i have been trying to fix it in the menu but playing around wit the constrast brightness and Color don't seem to do much other than brighten and darken the screen i think it might be an internal problem as i have had many people playing with the color settings to no gain. I was wondering if there was anyone in Singapore who could repair the tv or help me any other way if you are not in Singapore please still answer as I need all the help I can get
