Line in left side of screen

I have a 46" Mitsubishi LCD HDTV that has a line on the left side of the screen from the top to the bottom. The line had only been there when the TV was 1st turned on and would go away after about 15 mins.
I called Mitsubishi support and was told to reset the TV using the TV reset button on the side of the screen. After doing so, the line is constant on the screen and does not go away after it "warms up "
LT-46133
TV was purchased 10-07

White Band On Screen - Remove It!


if a white band is seen---go to a blank or unused video input and examine the screen---both sides---if it is seen on both (even if more so on one side) you may have burned the screen by using the 4x3 format.

If this it is permanent damage.

2 year old Mitsubishi LT-46149 46" LCD Flat Panel


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.

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

Screen damaged from fall, colored vert lines on left side from the damge


Unfortunately the LCD panel would need to be replaced. Even if there is not any signs of damage to the outside portion of the panel, one of the inner screens may have been fractured. I am not sure if the panel would be available because if i'm not mistaken Sharp just started making replacement panels.

Honestly you have a big problem because the driver IC & Tape Carrier Package inside controller board at vertical area are damage or itself defective could cause you have 2 inches line appear in your display. The best solutions for this replace lcd panel to fix vertical line.

The TCON board at the top of the panel is causing the issue. You will need to replace the whole panel.

When the set warms up, the TCON behaves. Replace the panel now to avoid what will eventually become a permanent line (if not several)
