PANASONIC (PT-47WXC43G) VIDEO PROBLEMS

I have a Panasonic Projection TV MODEL # (PT-47WXC43G) All the bulbs work (RGB) and it has sound.  BUT.... Only a small strip of video (about 3 in wide) in the middle of the screen shows up.  I looked for obvious burns in the board but didnt find anything.  Im hoping its something fairly simple...  Please help me out.  Thanks
