Okay, so what troubleshooting have you done:-
- Has the screen got power?
- Does the screen work anywhere else / can you put in a known good screen?
- Is the server running and on the network?
- Are there any attention lights?
- Is the server powered on?
You've not given much to work on, but I certainly wouldn't leap in and be pulling cards out.
