Troubleshooting issues with displays can be hardware or software related. Hardware related issues can be associated with power, cables and connectivity, the graphics card, or physical defects in the monitor itself. Software related issues can revolve around drivers, and display settings. Blank screens can be related to power, or incompatible or corrupted graphics cards. Just speaking from a logical, common-sense perspective, I think the first thing to ask when troubleshooting a display is to always find out whether or not the display is plugged in and powered on. This is probably the first thing to check for most electronic devices. Other issues you can encounter are burn in, which is a result of leaving an image on the screen for an extended period of time without changing causing the image to be permanently burnt into the display. This can be avoided prior to occurrence by changing your screen saver options in display settings. Another issue commonly seen can be flickering images which occur when images waver or vary in brightness on the screen. This can be a hardware result such as cables not being connected securely. It can also be a software related issue such as the result of an unsupported display resolution, or an incompatible display driver.
