The weather is wet, and there is a horizontal bar on the TV screen.

There are horizontal lines on the TV screen, so it is necessary to check whether the wires connecting the TV screen and the host are loose and plugged tightly. If it doesn't work, press the AUTO button on the display to manually adjust the TV resolution. If it still doesn't work, you need to contact professional maintenance personnel.

1. Stripes are horizontal lines: usually white. The main reasons are: 1, connection problems inside the TFT panel, signal input terminals and static electricity. Generally speaking, we can initially determine the cause by visual observation of defects. The lines formed by static electricity are generally single lines, which are not so thick. Thick lines are usually caused by short circuits. 2. The internal short-circuit signal input of TFT is short-circuited. The use environment is too humid, which will have a certain impact on the input line and produce line defects. But this is not the only reason. This situation should be solved by contacting the manufacturer after eliminating the reasons for its own use.

Second, stripes are vertical lines: usually colored. The cause of formation is similar to the horizontal line. One is an open circuit, many are short circuits. It is recommended to contact a professional for maintenance.

Third, stripes are crosshairs: relatively rare, caused by short circuit or static electricity inside TFT.
