Question about Mitsubishi LT-40133 40 in. LCD HDTV
13 month old tv
lines are 12 inches wide color
now constant; but started and stopped after tv was on for 30 minutes
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.

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.

My LT-40133 devloped a 3-1/2" banding line on the left side of the screen. It is very subtle and is only really noticable when brodcast colors are bright (whites or blues). Lucky for me I caught this in the 10th month of my warranty. It took them around 2 months for the service center to repair it because they had to order a new LCD panel. The tv was returned as good as new and I felt very fortunate to have caught this problem. It is now been 11 months since the repair has been made and the line is back! I guess I am just going to live with it..............

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.
