Learn about bad caps: http://en.wikipedia.org/wiki/Capacitor_plague

Capacitors kit: http://lcdalternatives.auctivacommerce.com/ he can make you a set of caps for you. Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

This is most likely due to the computer itself is not functioning in and this is the typical reaction of a monitor that is powered on and not receiving a signal from the computer. What is the state of the PC when you turn it on? Any lights, fans do you get picture at all on the monitor before the power saver mode kicks in? Most likely scenarios

• Video card is bad on the computer
• Power supply is bad on the computer
• Motherboard is bad on the computer

P.S. Even if you have lights and fans working on the computer one of these three parts can still be bad. You can rule out the monitor by plugging it into your laptop and toggling the display (generally done by pressing the FN key and F7 or whichever F key has a screen icon on it)
Comment back for further troubleshooting. Thanks!

I would say that it doesn't see any signal coming from the computer. Check your output. Check the video drivers. Try another video display.

check in your control panel under power options.
you can select a new power plan

Power board capacitors failing, what you are getting is the inability of the capcitors to hold the charge necessary to power the inverter to fire up the screen, means investigating and replacing the faulty ones

Does it do the same with another PC? If it does, then It may have unstable DC due to bad DC filter caps in the power supply.

If you are going to DIY and already try the monitor with another PC, 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 LG monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/ Post back what you see inside so we can guide you further and it will help out other people in the future also.

Your LCD screen is not recieving a signal from your computer. See my published guide, entitled My Computer is not turning on!!! Is it dead!!! No POST!!!
In this situation you would want to make sure your screen is working by trying it on a friends computer or connecting your computer to a friends screen.

All the best!

On my HP monitor on the stand, I have a locking mechanism that doesn't allow the display to be raised. I need to press a button on the stand while pushing down the display, then the button is possible to be pressed down. then while holding it down, I can pull the display upwards as much as it comes.

the stand locks in my case when pushed all the way in.

Maybe this is the same thing on yours? Maybe not?

push the auto adjust button

no inputs detected

interface cable or video card memory problems

check your video card and update the driver or pe install your video card. add cooling system. another is the motherboard capacitors

it needs repair

i think the problem is in the psu of the monitor, capacitor issues perhaps

push the menu button
