At first the color on the tv had an orange tint to it. Now the color is a dark blue almost black color and i cant see a thing. I took off the back cover and only the blue lamp seemed to be on. The green lamp had very little light and was very dim. And the red lamp had no light. Does anyone no what the problem is and how to fix it please help. thank you
