This could happen due to several reasons. There could be a slight crack on the screen or the panel. on the other hand, it could be the mainboard. needs further investigation.
First there was only one line on the left side and then they show more and more by time. TV stands on his feet all time, no movement to plug in anything. I cleaned all ribbon cables and if I switch the flex cables from left to right from the ton I got no picture, only noise sound of electronic failure. Maybe this is a point who is nice to know for pros
hmm. you might be having an issue with the video processing chip. ( so mainboard fault)
Thank u to spend time to answer in my case.. I will give the main and t-con a last chance in the oven for 5 minutes by 200°C. I will report what happens. The TV works 8 years, that's more as I expected.

SOURCE: sharp lc26sh20u 26"flat panel has vertical lines on left side,What coulb be problem?
This line would either indicate a horizontal problem cropping up or a power supply problem
I would suggest getting a service tech to look at it to determine where
your problem is coming from but most likely it will be the power
supply /deflection board that is the problem but I can't know for sure, it will have to be checked.
A lot of sets have had damages after a long hot summer a/c
flipping off and on and current demand being peeked from the
utilities storms or quick power loss off and on can cause problems
like this to occur
Please let me know if you have any other questions, thanks

defect in panel call Sony some of those panels have 2 year warranty.
Testimonial: "Sony replaced the panel for free and the TV is working great. The early models of that TV had a manufacturing defect causing delamination."
SOURCE: Two vertical 1'' white lines on right side of Lcd panel
If the lines are parmanent, Then suspected part is LCD Panel.

I really do not know there is the "Stuck Pixel Fixer programs" I think that Program Breakdown another IC. For this issue is absolutely the Plasma display panel have problem. You shall exchange it.
SOURCE: Toshiba 57LX177: Right side of screen darker than left
I am not sure...but I have the identical problem. I believe the vertical lines are caused by the inverter board and the darkness is caused by the one of the back lights that needs to be replaced. I am tearing my unit apart now and will find out.
