Blue band about 6

A 5" wide dark band in the middle of a Samsung Smart Series 7 TV screen could be caused by several issues. Here are a few potential causes and solutions:

1. Faulty LCD Panel: If the LCD panel is damaged, it may cause a dark band in the middle of the screen. Unfortunately, a damaged LCD panel usually requires a professional repair or replacement, which can be expensive.
2. Loose or Damaged Connection: A loose or damaged connection between the TV's internal components could cause a dark band on the screen. Check all of the cables and connections between the TV and any external devices to ensure they are properly connected and undamaged.
3. Picture Settings: The dark band could be caused by the TV's picture settings. Try adjusting the picture settings to see if it improves the image. For example, you could try adjusting the brightness, contrast, or sharpness.
4. Software Update: A software issue could cause a dark band on the screen. Check if there is a software update available for your TV and install it if necessary.
5. Magnetic Interference: If there is a strong magnetic field near the TV, it could cause a dark band on the screen. Try moving any magnets or magnetic devices away from the TV to see if it improves the image.

If none of these solutions work, it may be best to contact a professional TV repair technician who can diagnose and fix the issue. They can ensure that the repair is done correctly and safely, and can help prevent further damage to the TV.

It sounds like it was dropped or banged hard. I would suggest just replacing it.

Could you provide more information? What do you mean when you say, "closing?" Do you mean there is a black band around the picture? If so that means the original picture is recorded at a lower pixel density than your TV will display.
In the past most TV program signals provided a picture dimensions (in computer standards) very roughly 600 pixels wide by 400 pixels tall. What this means is that a picture of that pixel size will display as a small, squarish image slightly wider than it is tall on a (now) standard 1080p LCD television--which produces an image 1920 pixels wide by 1080 pixels high.
That would be nearly unwatchable (picture too small) except for the fact that most TVs compensate for the relatively small size of "standard definition TV (SD TV, as opposed to HDTV) by enlarging the image so that the top and bottom edges of the picture touch the top and bottom of the TV screen. This will leave black bands on either side of the picture. Some LCD TVs will automatically stretch BOTH dimensions of the image, which yields a distorted, "sqaushed" image.
All my comments above apply to both standard LCD and 3D-LCD TVs, by the way.

All projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

• Screen looks 3D
• Colors don't line up
• One or more colors can't be adjusted when using the convergence menu.
• Screen is bowed or warped.
• TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.

Here are some pics of convergence problems.






Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

The tv have a problems known as a convergence problems,it dead.The tv have colors lines R,G,B misalignments,have colors shadows pictures or 3D pictures look alike?The tv convergence board have dead 2 STK convergence ICS and some or all of it resistors are dead too.These parts on the tv convergence board,must be replaced to solved the tv pictures convergence problems.The shop,will cost u like $300-350 for parts and labors.

Hi and thank you for using fixya

Here is how to do your 3d effect

1-open illustrator

2-create new document any size you like

3- create image or object you want to 3d on artboard

4-select object

5- click on the menu bar click effect then click 3d then click extrude and bevel

6- you will get a menu with all the different options for 3d

Have fun

Thank you

Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs.

You will need to pull out the engine and check for any smudge on the lens. then proceed with the polarizers 3 of them they are sitting in front of the DLP chips, this is a delicates operation. the blue polarizer is the one which usually suffers burn-in (dark spots on the glass). if everything looks ok, then it means that the dlp chips are faulty, at that stage it will be uneconomical to be fixed.


Hope this helps!
