Monitor with problems [ Microscan G500 Professional 15'' ] An hour ago while I was watching some pics on net my monitor simply flashed ( this happened also in the past and after doing that I was turning it off and then on and that was ko ) . Now the image started to decrease and after that monitor turned off , and then after I press power it sounds an signal and nothing happends .. I ahve turned off pc also and haven't tried to start it again , came to my other pc to ask you about what can i do and what can be safe to do .
