No monitor - HW problem

[Dotan Cohen]

A Fedora 4 machine that I haven't touched in a while won't take it's
monitor out of standby mode. When the machine is started, I hear the
hard drive and fan spinning, and the motherboard give the familiar
POST beep. However, the yellow light on the monitor does not turn to
green, and nothing is displayed. I connected the monitor to another
machine (my everyday machine, where it is usually connected) with the
same cable and it works flawlessly, thus eliminatng the monitor and
cable as problem sources. I swapped video cards (A 32mb Nvida and
something else unknown), this did not help. Might the motherboard be
at fault? What can I check? The machine does not have SSH, otherwise
I'd operate it that way.

Thanks in advance for any tips.
