Very strange failure of 17" Studio Display

Question

I'm running a G5 with 10.4.11 and a 17" studio display. I was out of town for a while, came back night before last and started up. All peachy, no problems at all. I got a system update message, OK'ed it, then restarted when the download was complete. On restart, the screen was black. I know the machine started up and works fine; all the familiar sounds are still there, I can adjust the volume, etc. But even after multiple cold restarts, unplugging everything for half an hour and coming back, etc., no screen.
I find it hard to believe my display just died all of a sudden when it had no problems at all before. The power light in the bottom right corner still comes on, as does the other one in the bottom left (brightness? never use it), so I don't think it's a connection issue (also, the connection was fine up to the failure and nothing about it had changed). I am trying to track down someone with another monitor, but anybody have any idea what could be going on?

Answer 1

DVI (computer) to ADC (display) adapters are only for LCDs, not CRTs. Most do not pass trough the analog video signals needed for a CRT, and do not provide enough power. I have seen reports that the Gefen DVI to ADC adapter
<http://www.gefen.com/kvm/product.jsp?prod_id=1203> does pass the video signals, but the power supply gets VERY hot when running a CRT. You could replace the supply with a bigger one. I think you need 28V 4A.
