Jul 11, 2017
My TV recently started looking pretty dim. We first thought that it might be the lighting considering we had just got the TV couple weeks ago but then the TV's picture went out and now I have sound but I have no picture and there is a red and green flashing lights in the front of the TV so it flashes green and red and then my TV shuts off all by itself is it the bulb that needs fixefd
