Thin red line on TV screen

Hi,

I have samsung UA37D5000 tv. There is thin vertical red line appearing in TV. When I called up the local samsung service guys to check, they said they have to replace the panel and costs almost 23K. I don't believe in their words. Will you be able to tell if it's the real panel issue or some board issue.

If I have to open the TV, it would be helpful to have a teardown guide for my TV.

Attached the picture of the red line on the screen.

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.

Rajesh Ravindran yes Sir that is a Tab error. You'll have to remove the back of your TV and see where the flat ribbon cables enter the top of the LCD panel. Put some pressure on that cable and you should see the line disappear. LEt us know what you find. If you are unsure take pictures and post with your question so we can help you further.

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.

I hope this helps.

I just read this advice and got up and knocked on the top back of the screen where the line originated and it intermittently went away and returned so I squeezed the top and knocked it a few more times and it went away for good. Fantastic advice Angiel!!!

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 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.

The lines go away after the TV gets warm.

Does this sound like the TAB problem?
