Question about Televison & Video
if this is under warranty still, i would take it to a service center or rma it to panasonic.. if it is not under warranty, you can try the following.
1) try a different video source and verify the problem is happening on all video sources and modes.
2.a) if the problem is not happening in all modes, remove and replace the cable that is causing the issue. if this doesn't remedy the problem, the controller for that particular input is going out
2.b) if the problem is happening in all modes, you can open the case and carefully disconnect and clean (de-oxit or rid-ox) the hirose style connectors on the back of the display panel.
3) disconnect and clean all ribbon cables around the display panel
this sounds like either the connectors are not performing adequately or are loose, the top ribbon is acting up for some reason, or the graphic controller is going out.

For me it was the cable box settings...
I'm not a tech person, so take this for what its worth. I had the same problem with my Vizio and my Time Warner Cable HD/DVR box using the HDMI cord connection. HD channels were always fine, and non HD channels were fine until I went to an HD channel and back. When switching back, the non-HD channels would be shifted to the left as you describe. After much back and forth with both Vizio and Time Warner (each saying its caused by the other), I stumbled across the following fix...
I went into the cable box (scientific atlanta 8300) "settings", under "display," under "output resolution." There was a list including 480i, 480p, 720p, 1080i, and "auto select." I unchecked both 480 options and left 720 and 1080 checked. Problem solved. The other "Display" menu settings are as follows: Picture Size = Stretch, Aspect Ratio = 16x9.
Hope this helps.

it seems to be a bad connection somewhere but I disconnected the ribbon cable and got a verticle line of snow instead of a blank line. the line is about 34 mm wide and starts 285 mm from the left edge starts on the Blue and goes to the Red pixels. so if they are 1mm wide that would be 34 bands of color.
I would sure like to figure out the solution to this one or I got a TV I need to throw away cause the o'lady is gonna bust my balls if I can't fix this!
