Check power supply section for bad caps first. Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed ACER monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums Post back what you see inside so we can guide you further and it will help out other people in the future also. http://en.wikipedia.org/wiki/Capacitor_plague http://www.badcaps.net
Check your connections to the PC. Make sure that they are nice and secure. If there is a resolution problem setting it should display the boot process and then go blank after starting the operating system.
Some monitors have multiple settings. For example, mine has digital and anolog setting. If it is on digital, it will do exactly the problem you are saying, try finding a button on the monitor called source, or something along those lines.
