I messed up with my camera and now it's pink

Hi, i'm an electronic enthusiast, recently my Yoosee camera stopped working (normal light bulb also tend to burn in that spot), so i opened it to tinker with it and it came back to life! But now the image has a pink tint, everything is pink, i do not know why xD, i mean, i will try to buy better cameras and put it in a place with more stable power output in my house, but I am still curious as to why the image is pink XD, can someone enlighten me?
