I have a solaris machine that powers up and displays a blank screen?
All the keyboard, monitor and mouse are plugged in. It was booting fine before and when it was disconnected and re-connected (mouse/keyboard/monitor) it just powered on and came up with a blank screen.
One possibilty is your VGA card is faulty.If not, do this:
-use your notebook to serial in
-you should be able to see something
-dro system to OK prompt
-check the input / output device is pointiing to screen and keyboard.
try booting the system again. you will notice that your notebook gets no respond(meaning that your monitor and keyboard has got the signal).
Check again and see.
