Having problems with your PC Desktops ?

Have a Samsung SyncMaster 930B just went blank and a floating message says check signal cable, digital. I have check cables and find no problem....what else can I do?


Answers :

It means that the main board on the monitor is no longer functional you need to replace it or take it to a technician.
I would check the video card, see if it's still good. also check for your drivers and update if necissary.
