Rajesh Ravindran this sounds like a TAB error. You need to let us know which direction the line goes (horizontal vs. vertical. Take the back off and see if you can see the flat ribbon cables that go into the LCD panel. Apply some pressure on those cables at the place where the line originates from. If that changes the line you know that it is a TAB error. Sometimes applying that pressure is enough to fix it before replacing it. Take some pictures of what your TV looks like with the back off so that we can show your were the tabs should be. Also post an image with the TV on so we can see that line. Use this guide for that.
"Hello. I had the same issue a few years back with my Samsung tv. After taking the back panel and trying to also find the source of the problem, i watched a YouTube video with a man that just tapped the rear top of the tv were the lines where somewhat hard and the lines disappeared. So i did the same and they went away till this day.
We have a 52” Samsung 1080 HP flat screen tv with a thin red vertical line and a little thicker purplish-red vertical line. Do you think tab or panel? I tried to find a light background so you could get a good view. Thank you!
I have the same problem , only it was a red vertical line and I tapped the bottom like I watched on you tube and now have 3 lines instead of the red one , can anyone help
"I have two thin vertical lines near the center of the screen on my 13 year old 46” Samsung LN-T4665F.
Lines appear on cold start up. Squeezing the TV at the top, right above the top of the lines will sometimes change their color (yellow, red, blue, black, magenta), or make them go away.
