36" TV is 8 years old, has been working great, never a problem or glitch. Now TV turns on, picture comes on then goes blank for a split second, then goes blank again. Picture goes on/off, audio is never an issue, doesn't matter which input I use. I did notice that the tube has a much more of a greenish tint to it without any video inputs. Any help / advise is greatly appreciated. Thanks
