I had DirectTV until about a month and a half ago when I switched to digital cable with a HD reciever. Not too long after we switched out tv started acting up. It started with the left side of the screen the color was dragging, but when I moved the tv it fixed itself. Well as time has passed it started acting up across the top of the tv. From black lines jumping across to the entire left side of the screen will go black. You have to move it around and sometimes it will stop. This tv is not even 2 years old. Any help would be apprectiated. Thanks in advance.
