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.

if the power indicator goes light green then turn to red, you must check the power supply board. look for a bulging capacitors.http://en.wikipedia.org/wiki/Capacitor_plague.a panasonic brand capacitors with low esr is a good replacement just look for the ratings and value must be the same when replacing. then make it sure check the polarity the positive and the negative. just let me know if you need further assistance good luck
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.
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.
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.
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.
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.
