Computer monitor don't work at all.

My computer monitor don't work at all. The power indicator light don't lit up at all. Nothing comes on the screen. Totally blank. The remains like this even when pressing the power button on the monitor.

The power indicator lights works on the system unit (unit that contains the hard drive, floppy disk drive, cd-rom drive & motherboard), speakers & keyboard. Can hear fan running. Could play music cd and turn off the PC by using the short-cut method (by pressing ALt+4 & then pressing Return button) till I replaced the battery.

I changed the fuse in the socket, system battery (as mentioned above), switched off & on the wall socket several times and made sure the monitor cables are correctly and securely connected.

The computer monitor was working fine. No sign that the monitor was wearing out. Next time I tried to use the computer 2 days later the monitor suddenly stopped working. Monitor totally blank.

I haven't got another monitor or PC try on. I posted this message from a library computer.

So basically your monitor's power supply system died.
Nothing much a non-technician could do about it.
Get it repaired, if under warranty, get a replacement before the coverage duration expires.

Power saving mode


Power saving modes are automatic for some LCD monitors some have setting like after 20 ,30 mins to an hour the computer monitor itself will go into standy saving modes like power led switch indication go to yellow led lighting or the monitor of the lcd screen go blank if ur computer have no pictures for displaying as a screen saver modes.Power saving modes it best for uses if ur computer it on all day long.If u don't touch the mouse or a keyboard the monitor will go in the power saving modes for less electricities consumption for less stress for the monitor electronic components for working to hard for the monitor not to malfuctions sooner or the monitor life cut too short because the computer it on all day.

My laptops screen does not come on even though the unit powers up,i have tried another screen,and tried using external monitor,neither worked,the lights by power button also don;t light.


Did you check the power supply? They go bad and if you get no power, nothing else will work. You can check the power supply by plugging the unit into an outlet and then using a volt-ohm meter measuring the voltage at the cylinder which normally plugs into the computer. If there is no voltage (DC) present, then the supply is bad. You can get a replacement online or at the place you purchased the unit.

Amber colored power light on eMachine W3503


The amber power light indicates that your computer has been "sleeping" or "hibernating" and usually all it takes to restart the computer is tapping a key on the keyboard. If this is not the case, try holding the Power switch down for 6-10 seconds to force the system off. Restart in Safe Mode and try to find the settings for Sleep/hibernate, open the control panel and open the Screen Saver. Select "Change Power Settings" and set it for "Never" on sleep and hybernate.

Screen does not turn on but green light is on.


Green light indicates the monitor is getting power. Nothing coming up on the screen indicates, No Signal.

No signal from the computer. This means the computer itself isn't working.

A bad power supply in the computer can cause this. A bad power supply is the leading cause of desktop computer failure. It is replaceable, and can be done by the owner relatively easy.

You may have a computer tower that the Power light comes on, you hear fan/s spinning, (Including the Power Supply fan), and it sounds like the harddrive is running.

ALL the lights in your computer use less than 1 Watt.
EACH fan uses 2 to 3 Watts.
A harddrive sitting there spinning in an endless loop, consumes about 2 to 3 Watts.

A Processor uses 51 to 125 Watts. Depends on what Processor it is.

A weak Power Supply will have enough power for lights, fans, and that harddrive sitting there spinning.
It won't have enough power to turn on the Processor.

[No processor operating, then the harddrive sits there spinning in an endless loop, because there is no processor to find the boot sector]

For a test, connect your monitor to a know good computer. See if it works.
Now connect that other monitor to your computer.

Stuck in power saver


Try the unlock procedure: With the monitor on press and hold the "MENU button for abot five seconds and see if it resets. If that doesn't work tell me a bit more about the screen - is there any OSD (on screen display) or error messages? Is the power indicator light on? If so, what color is it? Blue indicates that that you may need to turn the brightness and contrast up...\ If it is actually in power save the indicator light will be amber. What color is it? If the light is amber and all the connections to the computer are correct and it still won't come-up then it's an internal problem and the protect circuit may be keeping the screen from lighting. Good luck... And let me know. Bill

Screen black


Bill, It could be your LCD backlight giving you problems. With the computer on and the monitor power LED green shine a flashlight in the lower left hand corner of your screen. Look for the ?Start? button, if your backlight is not working you?ll see a faint ?start? button if you look closely. Depending on the monitor this is usually and economically repairable problem. Let us know if you have any other questions and please don?t forget to rate this posting.
