Projector stopped workin with my macbook


My projector and macbook pro were getting along fine until yesterday. I've been using a VGA cable. I've tried to resolve the issue by reading forums and trying different resolutions. Also restarting unplugging etc etc. Is there anything else I should try with the VGA? Or is there another way to get the image from my laptop to the projector. Maybe some kind of adapter or media box that converts firewire to s-video or rca...??
