Server does not show anything in the monitor/display.

I have a problem with server HP DL380 G4. My server does not show anything in display/monitor.
I removed memory/RAM and started the server I am not getting the beep sound. So I arranged another motherboard and I still didnt see anything in the screen/monitor.
What could the issue I changed power supply as well. I just want  to start the server and run P2V and convert to virtual.
Appreciate your guidance.

If there is no beep problem is most likely motherboard or power supply. Since you already did the first one, I'm guessing it's the power supply.

Are the hard drive using RAID? If not, you could also try putting the hard drive in another system as a secondary drive and read it from there.
any lights on the motherboard, which give you a diagnostic aid ?

It is RAID5

-->any lights on the motherboard, which give you a diagnostic aid ?
Before chaging motherboard there was amber light after changing motherboard it shows green led but nothing on the display.

I cannot even see the HDD leds blinking.
Hmm, so you have put in a known good and working motherboard and power supply and still nothing? Are there any other parts in the server that you haven't replaced yet? I can't imagine a bad drive controller would cause this type of problem.

What about the iLO port? Was that configured and can you try that?

I didnt know it is configured. And I could not configure without display coming up.

Any idea about if I completely remove the HDDs and put the HDDs to the new server will it work and pick the same RAID?

I removed HDDs and the RAID memory to the new server and it worked.
Thanks to all.
HPE have a guarantee on Smart Array controllers, newer ones will pick up the config and  work with older arrays (obviously not SAS controllers with SCSI disks though).

THAT is good information that bears repeating. Glad to hear an answer was found.

One caveat to the Smart Array guarantee, if the controller fails and gets swapped without the cache module the cache is lost. You should transfer the cache module without disconnecting the battery along with the disks. Sometimes not possible if you have to replace with a newer controller as the cache won't plug in.
Check the monitor and make sure it is properly configured for the video output.  I had an issue myself where the monitor was running at 54 hz and the server port was expecting 60.  I changed the monitor to auto detect and it came up.
