Blank Screen Whenever the system is turned on the screen will come up then go immediately off while the comp boots up. I can turn the moniter off then back on to get it to come back up, but then it goes right back off. It remains off while the computer is on, but can be turned off then on to see what im looking at quikly before it goes right back off.

    Hold down the FN key and the press the Fuction key up on the top of your keyboard that has the icon of a monitor and see if that does it. That should change the output to the lcd on your laptop instead of the external monitor.

If the screen turns off check display adapter
or driver is going bad
you might need a new power supply

Power on emachine T6420 and moniter is blank. The moniter soon loses contact with the computer. The fan run and power is OK there is no beep code.

If you mean after the computer performs the self test the screen goes blank and stays blank, eventually turning off you are having a hard drive problem. When the computer boots you should see an E-Machines logo and/or a self test on the screen. That is done by the motherboard as part of every boot up. After that the motherboard passes control to your boot device and loads your operating system. If your computer stops booting at that point, your boot device is not working properly. That could be caused by many things - virus, hardware failure, power outage. If you really mean you see nothing at all on the screen when you press the power button your computer simply is not working at all. Open the case, blow all the dust out of it and reseat all components you can, then try again.

BLANK SCREEN

i think your system has crashed so you need to do recovery or do a fresh installation of your operating system. Your system is unable to boot due to corruption in system files.

Moniter won't turn on

SOUNDS LIKE POWER SUPPLY IS OUT OR POWER RELAY IS Bad.

Probably cheaper to replace this mointor with a new lcd which uses 50% less current.

even if you find the parts to fix it i suggest replacing this moinitor altogether electrical failure is a sure sign of other problems in the future.

My Toshiba laotp's screen goes half blank help!!

Well try to boot into the safe mode.hit F8 on the startup and see if you get the same acreen.If its working fine in safe mode than you need to reinstall the video driver and that should resolve the issue.If it is still not working try connecting a external moniter.If you get the same display on the external moniter than its an issue with the video card and if you get a normal display on that than its an issue with the Laptop screen and you would ahve to get either of thses replaced by contacting the manufacturer.
Hope this helps!
