All it means is if there is dirt or just hand prints and its really just a part how they made it just cause u can see it it means nothing.
Vertical lines usually indicate bonding tab issue, the screen would need to be replaced
That is cause by the speed of the camera recording and the refresh rate of the monitor or TV screen.
i think they do read from a tv screen
looks like a problem i cant fix
画面 (gamen) means "screen" as in a TV screen.
Generally most any TV problem can be repaired. Squiggly lines could come from a number of sources, like aged or dried out components and from different places in the TV. Without being able to see it, best thing is to call a TV tech with big screen experience.
screen as in tv or monitor sceen
A high-definition (or HD) television recieves a digital signal, while a standard television uses an analog signal. The HDTV is superior to its standard counterpart because it displays a picture on its screen that is comprised of more "lines" than a standard screen (typically double the number of lines). This increased number of lines in the signal creates a more clear, more vibrant image.
The screen could go "fuzzy", have lines or distortions, or go to a blue or black screen. Also the picture may freeze -- these all could be signs of a defective cable box.
screen size of any computer or tv screen is measured along the diagonal. so screen size 14 inches means that the length of the diagonal of the screen is 14 inches
If you mean a TV's actual size, you measure the screen diagonally
Why TV Retrace Lines OccurI am no expert, but I will try to explain A standard TV screen is made up of 480 lines from top to bottom. Retrace lines will only happen on a TV with a regular Picture tube (known as a CRT), they will not happen on a LCD or Plasma screen. So before I say how retrace lines happen, lets first get little understanding of how the TV puts an image on a CRT. The lines on a CRT are made by a device in the back (known as the neck)of the picture tube called the electron gun. By use of magnetic fields controlled through a device called a Yoke mounted on the neck of the CRT. Now the electron beam emitted by the electron gun is made to go across the front of the CRT screen that is coated with a layer of Phosphor that glows when the electron hits it. When that beam starts at one side reaches the opposite side of the picture tube it has to quickly return back to that first side in order to make that next line. On a standard TV, in order to make the image of a single frame, it creates this line across the screen 240 times from top to bottom, it then returns to the top and starts down again with a second set of 240 lines that fill in between the first 240 lines to create one full frame image of 480 lines, and it does this 30 times a second. Now the retrace lines you are asking about happens when a circuit in the TV known as the Blanking Circuit, fails causing the Beam that is moving from the bottom to the top of the screen to become visible.
