Bought a 32" JVC 100hz flatscreen, about a month ago. To be frank ,the geometry was terrible, along with some other issues. I've gotten a fair grasp of the sevice menu, so I was able to correct hese issues to the best of my abilities. However, two days ago, a new problem has emerged. There is an almost constant 'pulsing' effect on everything I watch. I have a dvd player, Xbox, video recorder, and cable box connected to it, and thought it might be feedback from one of these, so tried the old faithful of connecting and disconnecting, seeing if when something was turned off, if the problem went way. No dice I'm afraid, and it's starting to cheese me off, having finally gotten a tv, which I'm fairly happy with. Is it a voltage or power supply problem, that's suddenly appeared, or what is it? can it be fixed by the service menus? Engineers are generally incompetent, in my experience. Any help would be appreciated. Thanks.
