When troubleshooting display devices the first thing you should do is a visual inspection of the device and the cables connected to it for any damage or loose connections. The second step when troubleshooting is to check if the device is getting power by checking both if the device is plugged in and testing the cable by switching it out or using a multimeter tool. Another step that you should take is figuring out what type of display issue is occurring because many different types of issues include a burnt-in image on the screen, certain pixels dying, or the brightness being set wrong. If the issue is a burnt-in image you should inform the user to leave the screen turned off for a while because the image could’ve been on the screen for so long that the pixels start to stay there.
