My monitor works fine for 0.5 sec every time I turn on my PC and then nothing
When my computers starts my monitor works for about 0.5sec and after this nothing... The green light shows that the monitor is working fine but I only get a black screen. If I turn off the monitor and turn it on again it works again for 0.5sec and then nothing.. I've tried it in other PCs and it does the same thing. I imagine that the problem has nothing to do with hardware, but then whats the reason?? HELP ME PLEASE

Sound like the monitor is gone.
if it is still in Warranty, you can call Samsung. if it is out of warranty, take it to any computer repair shop. (cost may be prohibitive.) the last option is get a mew one.

try with restarting computer & press F8 at the same time. u will see a menu where choose "safe mode" & start the computer. in safe mode see the display properties, set the refresh rate & resolution according to monitors specifications, apply & restart again. if that does not work, replace the main board of lcd monitor.

this works for Dell monitors with a similar problem: shut down, turn off monitor and pc, turn off at wall socket, and remove power plugs from wall socket. wait about 30 seconds. plug back in, turn on, and all should be well? I have used this 3 times on a Dell PC with a Viewsonic monitor.
i have 3 hannspree monitors 2 were sent back for repair i replacement was faulty when i got it back the other one changes flashing colours never again i tried turning the brightness to full which helped for a time
5 seconds? Hmm, too long for inverter driver turning into protection caused by bad lamps. Also too long for PWM controller in the switching power supply. Rather looks like overheating of the FETs in the inverter, they are driving HV-transformers. Open the monitor, remove metal lid and observe inverter board. If PCB under and around these FETs is darkened, replace them. These Dells hard to open. Take the foot off and unscrew plastic cover. Then using flat screwdriver with wide blade separate plastic halves of the case, starting from bottom edge and moving to opposite. It might be sweaty.
Restart the PC and get into SAFE MODE. Hit and release F8 many times right after turning on PC. If it works, then go into your video setting and either change the settings or remove the video driver. Restart the PC and you'll get 800X600 screen, then reinstall the video drivers. IF it won't go above 800X600, screen internals are bad, LCD toasted. I've seen that happen with LCDs and older monitors.
Capacitors on the power board inside the lcd monitor have blown they can be replaced with new ones and the monitor should return to normal operation. service center or if you feel capable you can do it your self with a soldering iron and the correct caps that have blown you need voltage and micro faradays usually 25 v at 470 mfd (u)however monitors use different kinds and voltages can be different it will be marked on the side of the damaged capacitors. l8r
It sounds like your computer is putting the monitor in power save or sleep mode, and the monitor doesn't respond appropriately. The monitor might be faulty, or overheating. Make sure there is adequate ventilation around the monitor, and that it is clean and free from dust around the vents on the case.
Another thing to try is to check your computer's screen saver and power saving settings. Try turning off the "turn off monitor after [interval]" setting and see if the monitor still shuts off after several hours.
