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.

SOURCE: red vertical line down right side of the screen

hi

I think your TV have a trouble inside lcd panel
the controller board contains driver IC. Deffective driver IC can cause of line display.

Three reasons why one vertical line accross screen can happen in LCD;

1.The missing signal from the controller IC to
LCD driver.
2. LCD driver IC itself defective
3. Dry contact in the tape carrier package.

Use masking or electrical tape to mark it where the line was located. press it if the line back to normal but when release your hand came back i think it was intermittent. Open the LCD panel

SOURCE: Mitsubishi 40" TV, LT-40134 Vertical lines on left side of screen

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.

Similar problem with an eleven and a half month old LT-40148. Approx. 1 inch vertical banding line on left side of screen on all inputs. After about two weeks, same problem on the right side of the screen.

Fortunately this occurred two weeks prior to the one year warranty expiring.

Called Mits customer service and they referred me to an authorized service center who I happened to have dealt with before.

They picked up the set. The front panel (LCD screen ) had to be replaced. Set was gone for two weeks as parts were not in stock. There was no charge. I hope this screen last more than a year.
