this means your power inverter inside the monitor is dead. This little gizmo lights up the monitor backlight. They dont fail all at once, but slowly die and give problems like you describe, you can order these online for your monitor , or find one on ebay for under 30 dollars, but unfortunately there is no fix, other than replacing the inverter.
sorry. Please use the thumbs up rating if you find my answer helpful, albeit bad news.
Take care.

This could mean that you video card is bad or going bad. Also that the monitor is going out too. Its one or the other.Try to plug the monitor into another computer to test it first. It will give you an idea where to start. then move to the video card.
The high pitch sound is coming from the inverter. It is faulty and needs to be repaired or replaced. The inverter supplies high voltage to the CCFL lamp, this lamp gives the backlight to the LCD so you can see the LCD images.

This is a problem with the power supply unit inside the monitor, there is no easy way out here. If you keep on using your monitor like this eventually it won't switch on no matter how long you wait. Keep on using it like this for the time being without switching off anything but ultimately you will have to take it in for repairs or otherwise purchase a new screen..
Try taking on the back of the monitor and pulling the power plug all the way out of it for about five minutes and then plug it back in and restart the computer see if it solved it thanks
Not likely that you knocked anything loose.
Keeping it clean is a good thing and helps stop overheating of parts.
Power should be unplugged when doing this. There is a slim chance if
using canned air that at times liquid (usually freon) will come out and
could cause a temporary short.
Ironic thing is: Overheating is what yours seems to be doing.
The capacitors on the powerboard or inverter are more than likely
starting to fail from heat and age and should be replaced before it
gets worse and eventually burns out a part that is harder to get and
harder to diagnose.

if the green light is always on that means there is no prob concerning the power and the monitor itself. the problem seems to be coming from your graphic card..
try with another graphic card..
OR
you might not configure the screen resolution to the appropriate level..
can you run your pc correctly in safe mode??
Sounds like you've done all the trouble shooting. If you just need that extra nudge, I would agree... it sounds like you'll be needing to shop for a new monitor.
right click on the desktop. select properties, Gop to the screen saver tab, click on the power button at the bottom right and check to see if its set to turn off or standby the monitor, turn this off.
Keep the screen saver on and set it for like ten minutes.
Also, on the monitor itself, it may have a sleep or power save option set as the default. check all the monitor settings on the actual moniotr itself.
