I had a similar problem with my LCD screen TV, and to my dismay, my warranty just ran out. A thin red line began to appear on the right side of the screen, and since many online and expert sources pretty much say replace the expensive LCD screen or get a professional to fix it (in which I suspect to be a business plot to get people to go to pricey experts), I decided to look for other possible alternatives. 
Here is some tips/solutions I was given (and it worked! at least for me): 
1) Turn off the LCD and unplug the power source and let it rest for 5-10 minutes. Turn it back on and see if it disappears or improve. (This is the one I used.)
2) While turned off, try jiggling gently all chords connected to the TV (cables, power chords, etc.); you could even try unplugging and replugging the chords/cables. Turn the TV back on and see if the red line disappeared or improve. (This is the one I heard worked for others.)
If the above doesn't work then I'm afraid you do have a bad panel on your screen and will need to call in the experts or get a new TV. I hope this will help. Best Wishes.

Unfortunantly you have a bad lcd panel or control board, but the only way to get the lcd control board is to order the panel. Philips does supply lcd panels for most of their models but they are very expensive. Sorry for the bad news but I hope it helps you.

    I have the exact same as above, Sony Bravia 4100 W series about two years old. Today a thin red line appeared on the right side. I troubleshooted and nothing helped. Eventually today it went away- so we will see how it progresses from here.

I have a Samsung LCD. I have parallel lines on the middle of the screen from top to bottom... I'm not sure if this is a re-call issue. My TV is 3 yrs now, and I noticed this a couple days ago. Although, something with the capacitor was messed up on this TV about a year after I bought it (the TV took a long time to turn ON) and some tech sent by samsung fixed the problem.

While a permanet line of any color indicates a bad screen wheather hot or cold, I believe a intermitent line coming in from the sides L or R after warm is another issue and possibly not the screen.

    this thin red line fades away if i change color temperature and contrast such as in game mode their is also red haze in the black color areas of picture and boarders like a vidio card issue and /or auro borealis in the skys. it is a garage tv now, and would still like to find out if it is a vidio card issue.. I personaly dont think it is the screen , however the backlighting has issue and may be the root cause.. Hmmmmm

I have a 42" Sceptre that too has a thin solid red vertical line going down toward the left side of the LCD screen. I'm told it possibly needs a t-conn board & that it's pretty easy to fix myself. What do you think???

Sanyo flat screen tv about 2 yrs old has thin colored horizontal lines down the right side


Nothing you can do about that...get used to it or change the TV.
It's a defect in the panel that can't be reliably fixed.

More than likely your control board. Available at www.partstore.com Cost could be between $130 and $200. Not that complicated to install if you can use a screwdriver and are careful. Let me know how this works out.

Red thin line on left side of screen / black colours have a burnt red tinge over them. TV is 30 months old


If that line is permanently on the screen  - even when you are using the AV signal then the LCD panel is busted, no way to repair it. Try getting it replaced under warranty, it shouldn't have failed so soon

Pencil thin red line going down lefft hand side of screen


Unfortunately, pixel thin lines are usually failures of the actual panel. If you can touch it and effect the problem, it depends on where. If it is in the middle of screen or away from the edge, you have broken connections on the TFT layer of the lcd panel.. meaning you need a new lcd panel. If you touch near the edge to effect, it is possible that the ribbon cable inside the lcd panel could be reseated to resolve. Opening the tv is one thing, but opening the lcd panel is another, its quite tricky and dust can get in between the layers. Only attempt if you have good disassembly skills and some compressed air to keep the dust out of there. The ribbon cables are very fragile and repairing by reseating is a hopeful but unlikely solution. A new lcd panel costs about as much as a new tv. Might just live with the issue or use as a tv for the kids.
