Hooking Mac Mini 1.83ghz to Sharp LCD TV

I have a Mac Mini 1.83 ghz Intel Core 2 Duo that I'm trying to hook up to a Sharp Aquos 32" LCD TV model LC-32GA5U. I've hooked the Mac Mini up to the TV using the DVI port on the back with a DVI/DVI cable, DVI/VGA cable with the DVI adapter to the Mac Mini, and a DVI/HDMI cable to a HDMI router, all of which have come up with a black screen, except the DVI/HDMI option. That started with the usual light gray screen and then it went to black.

The Mini starts up fine, I hear the drive turning, the front light comes on and I hear the start up chime. I hooked the Mac Mini to a 15" Dell LCD flat screen monitor with a DVI/DVI cable and it worked fine. I was able to run through the initial setup procedures without any problems, so I know it's not an issue with the graphics output or the cable.

If anyone has any ideas, they would be greatly appreciated.

Thank you for you time.
