Wait until the room cools down some before trying to use the monitor again.Īlso, if you're using an older CRT monitor, upgrading to a newer flat-panel display resolves many heat-related issues in a hot environment. If the computer room is very hot, cool it down by turning on a fan or the air conditioning system. Then, if you have canned air (anti-static, for electronics), try to blow out any dust inside the monitor casing. If the monitor is overheating, unplug the monitor and let it cool down fully before using it again. Causes of overheating include dust build-up, excessive heat or humidity, or blockage of the vents that allow the heat to escape. When a monitor overheats, it shuts off to prevent damage to the circuitry inside. One reason the monitor could shut off is because it's overheating. It's operating according to your power management features. If your computer turns off when not being used, but wakes up when pressing a button, there's nothing wrong with your monitor.
