Dimness On Screen

Noticed that the lighting on our 67" Samsung Rear Projection is dim. All colors are still present, but the lighting is dim. After researching we found this tv is powered by 3 led lights (red, green, blue). We don't know if one of these bulbs is goind out resulting in the dimness of the screen since all three colors are still present. Also, none of the indicator lights on front of the tv are blinking. Just wondered if there are any other components of the tv that could be causing the dimness on the screen?
