Open the back cover and check the fuses on Y Sus Board and X Sus Board. If you can find a blown fuse, just replace that board and your problem will be fixed.

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!

This model was known for issues with the Y-sustain, Y-drives, and the Z-sustain boards. These boards help process the picture image to the screen.
When one or more of these boards fail, the screen stays black, and you only have audio & on/off.
You could call LG and try to get your TV repaired at a discount if you can convince LG to honor this known issue.
Another issue could be the actual panel has gone bad. The plasma panel in your TV has a two warranty and LG would fix that for free. Well…it would be free as long as it’s not past two years of your date of purchase.
What zip code are you in?

Ok, first make sure you or someone in family didn't hit the "HD Zoom" on your cable remote or whatever kind of remote you have. On ours - Cable- if you hit it once it is in "Normal" picture which on ours has black around edges on a non Hd channel. Then if you hit it again it Zooms once makes pix very large and if you hit button a third time brings it into a wide screen Zoom that fills the Tv screen. If we are viewing HD channels I put it on Normal which will fill the screen and give you the best HD pix. If we are viewing a NON HD channel, then normal will have black on sides, so I hit the Zoom a couple times to fill in the screen. My brother in law had this problem and couldn't figure out why his Sports channel Scores were always half cut off the screen! it was zoomed in too much for that channel. His sports channel was in HD so needed to be on normal instead of zoomed in.
if it is not the Cable remote then this is a second possible cause:
The other thing that happened to me was - we hardly ever use our original TV remote that came with the TV. but one day our picture looked weird and the cable remote didn't adjust it. One of us had hit the "P SIZE" button on the TV remote. this changes your pix from - 4:3 ratio to 16:9 ratio and vice versa. I put clicked that button and on the TV it shows whether it is at 4:3 or 16:9. For newer wide screen TVs you want that set at 16:9 ratio.
All cable company remotes probably are a bit different so check with your company ... to find out where the zoom control is on their remote.
