Screen goes black then flashes grey to black.

1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or flashing, but nothing displays, borrow a monitor from a friend. If that works, your monitor needs replaced.

Anyone answer this? This is really annoying!

Your computer is in sleep mode, a low power mode that conserves power by turning off the screen and hard drive.

Push the power button on the system and the computer will resume.

If you don't like this feature, you can turn off sleep mode in the power options in Control Panel

When the system is going back into sleep mode what color is the power button flashing. It should like the system my not be going into sleep mode but have a more serious problem.

Also let me know what you see on the screen as you turn on the system.

Another thing to try is after you unplug the system hold down the power button for 30 to 45 seconds. This will reset the power state of the system. Note if you have the system plugged into a power strip you will want to reset the power strip too.

The high pitch sound is coming from the inverter. It is faulty and needs to be repaired or replaced. The inverter supplies high voltage to the CCFL lamp, this lamp gives the backlight to the LCD so you can see the LCD images.

it is going into sleep mode, good luck with this.... i am currently asking how to get my hard drive to quite putting my monitor into sleep mode.

although it hasn't worked for me because my screen stays black, one of the options given to me is to try to start in safe mode and then adjust your settings to "never" on the energy/sleep/hibernate mode

some one else suggested that i remove and reseat the video card

hopefully one of those will work for you

Next time you reset, check both the monitor settings and your BIOS settings for wake up

Is this monitor and LCD flat Panel? If so this is due to a bad power supply, an inverter board going bad or LCD backlight bulb blown. When the backlight goes bad it gets just enough power to start up, but when it is on for a long period of time it goes black because the bulb is not stable enough to hold the charge because it is going bad. These bulbs can be changed, but they also can be costly!

Same problem here. Does anybody have an answer?
