Can’t get rid of red vertical line on Vizio tv screen.

I have a permanent red line going down the left hand side of my Vizio TV . It’s there even when the tv is on but the screen is black. Model M70-C3

Here is a photo.

i have tried disconnecting and reconnecting the cables to the tc board and the pressing at the cables going to the screen by the line both did nothing to change the line.

Pressing on the screen will make the line slightly fade for a split second or two but then the red line of pixels just comes back. The line also fades toward the bottom of the screen for the last 6 inches or so.

@amongiello that most certainly looks like a tab error. TAB is the way the very thin ribbon cable that enters your LCD panel from its control boar, is connected. Remove the back from your TV and find that cable on top of your panel. (Small ribbon cable the enters the panel right where the line is) Press on it. That will most certainly change the line. Problem is that you cannot really fix it. Sometimes wedging something between the housing of the TV and the top of the panel provides enough pressure. You’ll have to play around with it a bit to get the best point of pressure etc. If unsure post some pictures with your question so we can see what you see. Adding images to an existing question

Remove the cover of the TV and find the ribbon wire that supplies the LCD of your screen. Clean it with a contact cleaner for possible lose contact. Then try to turn on the TV. Most cases lost contact is the cause of that line.

After checking for possible lose contact but the problem still appear, that is more likely the T-CON Board was partially defective. You can replace the t-con board whole assembly. That is available now in the market.
