SOURCE: monitor goes black............

try checking the cables first.

Posted on May 28, 2009

SOURCE: Power on - blank (black) screen

Disconnect the monitor signal cable from PC and switch on your monitor. It should show some logo with Red, Green and Blue colors with a message similar to "No signal". If so, your monitor is working fine. Sometimes if the brightness and contrast is set to zero using controls present in the monitor, it will not show up anything. check wheather somebody set your monitor brightness and contrast to zero. If so incease them. As a last try connect to different PC and check before approaching a service center. I hope this will help you out. :)

I have a Dell Dimension E521. When I cut the power on everything comes on including the monitor, but the monitor will stay black. It does say something about power save hit any button but the screen


A solid green light means the computer is operating normally.

A solid yellow light indicates the power supply is operating normally but the computer is not processing data.

This could mean there is a problem with the CPu or another component on the motherboard.


((A blinking yellow light indicates the power supply is receiving power from the wall, but not functioning properly.
This generally means the power supply itself is bad and should be tested or replaced.))


A blinking green light means the computer is in standby mode.

You should consider visiting Dell Support and downloading the manual for your

your Dell computer. So use the LED power light codes if your Dell computer has them.

hope this helps

My dell optiplex light is solid yellow


That usually means the switch on the power supply has been moved to 220v vs 110v. The switch is located just above where the power cord plugs in.

If you tried to install a BIOS up-grade and it failed, then your motherboard is toast.

Monitor won't come back from "sleep" setting.


Yes it can be, try it on other PC first to narrow down the problem.
Most problems in the Dell are failed transistors, poor solder works, see pictures here for guide: http://s807.photobucket.com/home/budm/allalbums

Powerbutton flashing yellow


If the main power button LED is flashing or solid yellow, this could indicate a hardware problem.

 

Was it running good before?

 

Are the diagnostic LED lights all green?

 

Here is what dell says:

 

If the power light is blinking amber  —

 The computer is receiving electrical power, but an internal power problem might exist.

  • Ensure that the voltage selection switch is set to match the AC power at your location (if applicable).
  • Ensure that the processor power cable is securely connected to the system board.

Do you remember what the BSOD said?
