I have a old HP-UX machine (HP-UX 9000/755).
Today, I found the monitor (A4033A) screen was just black. I'm not sure the system works properly now because the monitor didn't show up anything but black screen and I couldn't access this system remotely. I used to use the system a few weeks ago remotely but I failed to access today.
The power of the monitor seems o.k. I checked cables but I couldn't find anything wrong.
Thanks for any suggestions.

There are five LED's from top to bottom. The top one should be green and indicates the system has power. The 5th one on the bottom is your heartbeat and should be flashing.
If you will post what LED's are lit and not lit on the outside LED's, then open up the door on the front and tell me what LED's are lit and not lit of the 8 LED's inside we can pretty well diagnose what you problem is.

The top one is green and third and fifth is flashing, as they were second and forth LED of the 8 LED's inside.
I appreciate any reply.

Move the CRT to another system and see if you can get it to work. If not, then it needs to be repaired.
Try and put some other systems's CRT on your 755 to see if it is all right.

2 Network Transmit in progress
3 Network Receive in progress
4 Disk access in progress

During bootup the 8 LED's inside the door of the unit have the following meanings:

Thank you very much.
The attached file you loaded is not opened.
Could you please reload again. I really need the information.
By the way, should I turn off the workstation when I change the monitor? If so, I have to power off the computer because I could not access the system remotely.
I maybe find a same monitor in the campus.
Thank you again.
