If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed DELL monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

My monitor seems to be stuck in sleep mode


This happens when there is no communication with video card. Check cables, re-seat video card, make sure monitor is set to correct mode. VGA (15pin blue), DVI (white), or HDMI.

That means your monitor is not receiving a signal from your video card.

A couple things to check:
*Make sure your cable is ok - unplug and replug the cable to see if it is a loose connection. Or try a different cable.

*Make sure your computer is not in sleep mode - Move your mouse or otherwise ensure your computer is awake and sending a video signal

*If you have another computer, try the monitor on the other system and see if it works.

Hello,
May be the problem comes from the Cpu.
Try to see if the cable from the monitor is firmly connected to the cpu.
One thing more may be the vga card is having problem.
Try to test the screen with another Cpu. Or the cpu with another monitor.
The amber mode is normal as the screen is not receiving signal from the cpu.
At times the memory chip also report this problem (no display or sleep mode)
Do hear any beep sound or any other Errors??
OK try this
Cheers Uttam

Since you tried the monitor on another computer and its doing the same thing. The monitor is the issue. If you can open up the monitor look at the capacitors. Good capacitors will have flat silver tops. Bad ones will look puffy, bloated, pregnant, etc.

You will need to have soldering skills to do this. If you find bad caps then replace them with capacitors of the same UF rating and at least the same voltage or higher. The striped side of the capacitor needs to be aligned with the striped side off the board before soldering the new one back into place.

If you don't find any capacitors that are bad then the screen is the culprit and you'll need to find another monitor.

Sharp light turns green thern turns yellow screen goes black


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

LG Flatron L1710S Monitor stuck in Power Save Mode


Try wiggling the Cord on the backside of the monitor.. Not the Power Plug Cord, The Other Cord that attaches to the PC. Do this once the monitor turns off , grab ahold of the cord about 2 inches from the back of the monitor, then bend the cord to the right, keep bending from the right to the left a couple times to see if your screen comes back, if it does, than you have a Loose connection and this sometimes causes the Symptoms you are receiving.. Hope it helps.

Powersave


If it's going into powersave mode, it usually means it's not getting a signal from the video card. Try plugging this monitor into another machine or laptop and you should be able to tell if that's the issue.
