If it still doesn't work after a pram reset, you can try resetting the nvram through open firmware. Startup the cube and hold: Command+option+o+f Hold that until you get a white screen with some black text Type: reset-nvram (press enter) Then: reset-all (press enter and the cube will restart) Hope this helps.

I hope someone can help me. the other day our power went out for just a moment but since then, the monitor says the video input is not supported. I tried an older monitor and then it said: Attention Out of Range H: 79.8 V: 98.5 Hz > Not being able to see anything i don't know what I can do. I also have a pc keyboard so it is hard if not impossible to try a keyboard shortcut to rebuild something or? Also, only a couple months ago I had to replace the original monitor, but since the power button on the cube itself is not working anymore, I still have the giant old monitor hooked up to the cube as it is the only working power button! I really hope to keep my wonderful cube running and would appreciate any and all ideas you might have. > > thank you so much, > > Lisa Davy > Laconia, NH > _______________________________________________ > Cube mailing list > Cube at listserver.themacintoshguy.com > http://listserver.themacintoshguy.com/mailman/listinfo/cube
