Have a widescreen flat panel that has 4 vertical lines. 2 on left side, 2 on right side. 1 set where the 480 resolution screen ends, one set where 720 ends. Only see them when running wide screen. Set is 2-3 years old. This started after viewing a copied DVD. DVD aspect ratio was 2.35:1 instead of the normal 2.40:1. Could this have damaged the set? Also the lines are there on all the inputs. Movies were viewed on set using a playstation 3 as the player. Any ideas? Can the software in the set be reloaded? No service contract on this.

I assume your Misubishi is not close to anything electrical. However, it sounds like you have had an interference for some time. This will ineviteably cause the HDTV LCD to collapse. LCD's don't respond well close to heat. Is there a vent close? LCD's do well in a properly vented area but with all this said.......they will pick up interference from anything electrical. A few questions to ask ones self........are there any wireless devices or chargers close to the LCD? Might there be an oven, a/c unit or other wiring with 220 volts anywhere close to the LCD such as in the wall?
The Mitsubishi LT is a very reliable, multi component ready set that allows great viewing with surround sound. However, stop and think about this interference. It is not something in the unit. It is an interference. Look hard and when you've discovered it.....you won't believe how crystal clear this set will be.
Let me know what you find...Thanks for using Fixya and add any comments that may help us help you.

Bad/Going Bad/Will go horribly bad TCON board (small circuit board sitting at the top of the panel in the back).
Most likely, the whole panel will need to be replaced in order to rectify the issue.

I've got the same TV with the same problem. Sometimes by moving it on the stand the lines will go away but it only sometimes temporarily fixes the problem. For a while it seemed like it needed to heat up to go away but that is not the case. It seems like there is a bad connection somewhere but i cant seem to find it. One day, one thing will fix it, then the next day it wont do the trick. It gets very irritating.

That is bad sign of the bad LCD panel itself, but you can try replacing the LCD driver board first. The new LCD panel will be very EXPENSIVE! It will get worst as time goes by.
