I have a Samsung LNT5271f LCD tv.
the image keeps changing to a negative image both with and without anything plugged into it. I had read that going thruogh the Plug and Play on the menu might fix this , but I can not access it as it is not highlighted. Also someone had suggested holding the exit button on the remote until promted to reset , but this does not work on my TV. I did reset through the pic menu but that did not help either. This problem comes and goes but it has been stuck like this for days now. Any help would be greatly appreciated.
