Hello,I have a sony vaio vgn-nr220. I broke the lcd screen and cannot get my external moniter to come on. all I get is a check signal cable' message. I know it works fine, its been hooked up since the screen broke and I used it. It was disconnected for some reason or another and hasn't worked since. Any help would be greatly appreciated.
