Why the headrest DVD player disc cannot be read after opening the cover

After closing the disc cover, the headrest player displays "Open" and the disc cannot be read

Some guests reported that they were unable to read the disc after closing the disc cover and seeing "OPEN" appear at the top left of the screen. We also attach great importance to this topic. The reason for this problem is that the disc cover is slightly displaced, so it cannot be pushed to the switch after the disc cover is closed. The solution to this problem is also very simple. Just stick the gasket on the plastic column as shown in the picture and extend the length of the plastic column to solve this problem perfectly. The following is a reference image.
