Just thought I'd share this just incase anyone has this problem and tries to search the forums for it.

I had my 19" LCD screen go blank and report "Out of Range" immediately after the initial screen where you can select boot options (cheat codes), and linux would start to boot. Then the screen would return right when X Windows starts. Shutting down would also cause the screen to go blank again since it's exiting X Windows.

If trying to set the refresh rate with the vsync/hsync commands doesn't work. Try "vga=normal" with no quotes as a boot option. worked like a charm. Also had display problems on my laptop that this seemed to fix it too.

Hope this helps someone out!
