Question about Computers & Internet
Assuming the system power comes up, does the monitor power come on? Most monitors have a status LED on the front bezel that should show green, orange, or blinking if the monitor is powered on. You can hear CRT monitors power on with a gentle sound, though I can't describe it beyond saying it's the sound of a CRT tube warming up. Make sure the monitor is plugged into a good outlet by testing the outlet with a lamp or any other device that will prove beyond a doubt that the outlet is good. Make sure that the power cord is either permanently attached at the monitor end or that it is seated fully in the socket, since partial cord insertion is the most common failure for monitors with detachable cords.
LCD displays don't make any sound when you turn them on, but they don't have a simple power cord, either. Older LCD monitors are usually powered by an external transformer, which in turn is powered from a regular AC outlet. If the LCD display doesn't show any signs of life, make sure that the cords into and out of the transformer are fully seated. Some transformers are equipped with a status LED to show when they are operating. The power connection to the LCD display is often awkward to inspect, recessed into the back of the display. The important thing is to make sure it is started correctly, then seated all the way.
