According to the model type, it has likely reached the end of its service life. It would cost a great deal more to have it repaired than to replace it. Here is an example of an inexpensive alternative in the new market ( http://www.walmart.com/ip/Acer-ET.LBF09.030/5013901 )and there are thousands of used lcd monitors available from places like Ebay.

try to press the recall botton is it works then good for you...
If not then try a degausser tool.

if it still have the same problem after using a degausser tool, then there might be some parts of the monitor which is defective..

my AOC crt monitor 5En model has this problem. it has over width the compress button (<> ) is no longer functioning what particular component should i check or adjust inside the circuit? please i need ur help..

Then the issue is inside the monitor itself. If this is a big CRT monitor I would NOT recommend working on it yourself as it is basically one big capacitor with a bad attitude, you may see if there are any monitor repair technicians in your area. But you may be better of just replacing it as they are very inexpensive now adays.

actually if u repair an aoc monitor alone without getting connected to cpu once u switch on the monitor all led's will lit on ( green light ) it will remain on situation until u connect the vga connector to cpu that's the time led's will lit off and only the power led will remain in green condition.some aoc 5en once u power on power led is in green condition and if not connected to cpu it will be in orange condition.hope u get some idea but i am not sure if it will work with ur monitor. but as long as LEDs lit on i think no problem with ur monitor.

u try to reorient ur vga connection it might be a loose connection between ur monitor and ur cpu otherwise ur vga cable is defective...

I think it's the refresh rate.
In XP:
Right-click, properties on the desktop
Select settings tab
Hit the advanced button
Select the monitor tab
hit the box (hide modes that this monitor cannot display)
Select a new screen refresh rate
hit ok twice.

check your display setting might be to low for monitor

just change the botton switch.... with a new one...

just try to change the horizontal transistor C5386 or CXXXX... with a new one....

replace the vertical IC (TDA9302h or STV9302a) or the capacitor near the vertical IC... the value is 16v/1000uf.....

its eht get faulty change it

first make sure its not the monitor... connect bad one straight to the video card and see if u get video if so then check, control panel / display / settings, are you still multiple monitor mode? try and identify also
