Does it come and go? I would try reseting the ribbon cables between the LCD panel and the T-CON board first.
The Flexible Printed Circuit BoardS (FPCB) are ultrasonic welded to the LCD TFT panel, they are not SOLDERED on! The connections do get bad due to very delicate nature of how the LCD panels are made. You can also try squeezing the around the top area of the screen where the lines are to see if the lines go away.

It is possible that you have a bad power supply, or the TV has been hit by a small power surge and if you unplug the set from the wall for 40Min., it will rest back to normal.

Misubishi LT-46244. On the left side of screen there is a fine black line that goes from top of TV to bottom of TV. It almost looks like a string of emitters are off.


That is a good guess. You have a row of lcd's that are bad. The only fix for this is to replace the lcd panel. This is very expensive. You should just buy a new tv.
