Please help me see if this 12864 is bad. [Copy link]

There was a line in the middle on the first day and it was the same the next day. Is it a problem with the line or the LCD itself? I feel like the screen itself has a problem.

It is best to find a good program to try, this generally will not cause any problems

The second line is not lit when the power is turned on. Is it related to the program? And I didn't re-download it. It was displayed before, but there was a dark line in the middle of the screen.

If this happens, there may be something wrong with the screen. Replace it.

Take a confirmed good screen and replace it with the new one, leaving the other screen intact. If the new screen displays normally, it is basically confirmed that the screen is damaged.

The second picture looks strange. The color of the pattern is not right. It is probably a hardware problem.
