17" Apple Monitor ceased to display, how can I test it

My 17" Apple monitor suddenly ceased to display. I can't see what I'm doing! It has the two USB ports occupied by bluetooth and usb speakers both of which function ok. The power light behaves as normal. Is it possible that the actual display matrix can have gone? Is there any way that I can test or check it to assess what the problem is?
Any help would be great. Ta

Hello, and thanks for your responses. Its a 17" LCD screen.
When its connected the power light on the front is on permanently and does cycle through any sequence.. I'll try and check it again re the dimmed desktop when I reattach it again to test it out.
I guess I was wondering if it is possible to short out any circuits when attaching a USB 2 device to a USB 1 port as on the back of the monitor. I wouldn't have thought so but I'd be interested to know if anyone has any other input. This was the only change to my set up was when I attached my LaCie USB speakers to the usb port on the back of the monitor. They worked fine for a few days and then one day the screen wouldn't function.
Thanks for the link to the forum but it appears that the monitor I have is of the older variety of cinema display which uses the ADC rather than the newer models which may have a separate power supply. If I could check this monitor on another mac then I could maybe do a wee bit more analysis but due to the ADC connection then its not so easy to find another MAC of that vintage which has the ADC monitor connection on it. Also having to pay around £70 for and adaptor ( http://store.apple.com/uk/product/M8661B/B ) to allow me to connect it up to a powerbook to test it seems a bit much when the monitor may be worth nothing if it is completely dead.
I'll continue to try to resolve and understand this as I don't want to just dump the monitor if it is just a relatively minor issue to be resolved. Any thoughts are gratefully read.
