Hi, I dont know much about TV's, so I was hoping someone with a better understanding than myself could offer some advice on a problem I have with my TV. I have a Samsung rear projection TV, today when I turned it on the picture appeared very green and the sound is gone. The picture is still there and clear but is looks like the green colouring has has been turned up way too much....similar to when you adjust the brightness. Sometimes the picture (normal colour) and sound come back, but only for a few seconds. It is a big telly and a mission to move so I am hoping it is something simple. I hope someone has a suggestion.
