i have a 19" cicero(model 900p) flatscreen monitor that turns off all the time..i dug out my old crt moniter so i can try and troubleshoot the problem.(by the way my old monitor works fine and i only have the one computer here so i cant plug the broken monitor into a different system) i tried to search the name and model number and noting comes up...is cicero a real name and/or is made from different manufactor name...either way i need some help....

p.s. i also made sure the cords were fine and is ok
Step by step, what do you see from the moment you HIT the 'on' button?not sure which on button you mean ...the monitor or pc......however pc:the computer STARTS normal the start up screen APPEARS and then DISAPPEARS i turn the monitor off then on again the display appears and then disappears...this process is repeated off...then on....apears then disappears...also i might add when the display is gone the monitor light is still on green....also the other day my wife just told me it happened and she turned monitor off for about hour turned back on and worked fine until today...i turned it off for about three hours this morning plus unpluged my whole system and plugged everything back in again....    Can you start the computer in safe mode?sorry i FORGOT to mention that...it was the first thing i did and the same thing happens the picture just disappears
I think you will have to try that monitor on a different computer.
