I'm facing a strange problem with my Dell PowerEdge R740 that there is no DATA coming from the VGA from the iDRAC and also even with a physicals monitor connection. iDRAC says (NO SIGNAL) and with a physicals monitor connection, no data is showing-up.
iDRAC is working fine, showing everything expect the RAID controller and the physical HDDs.
I tried to do NVRAM rest then also tried to remove the CPUs and the RAMs and tried to remove the RAID controller but without any luck.
Note: In the SupportAssist file, All my hardware is showing even the RAID controller and the physical disks with their firmware details
Thanks for your reply. Please note that The embedded VGA is enabled and I tried both VGA ports rear and front with the same problem and I don’t have KVM.
Please note also that this server was working fine and this happened suddenly with any changes to the server or even firmware update.
Did you know whether your system is actually booting or it is a video issue. You can check this by trying to access operating system remotely after sometime of booting or by checking POST code on iDRAC (Maintenance -> Troubleshooting page). you can also check boot capture on this page to see whether video is captured on boot capture. I would also recommend to update iDRAC FW again and check the behavior.
Thanks for the details. By checking remote OS I want to see whether vDisk is not actually working on the server or iDRAC only not showing virtual disk details. Is POST code showing any message?
Hi, I'm not sure if I could conclude this as a mainboard issue. To have the deduction, you will need multiple part swapping, cable connection test and etc…

Hello moabdelaal,
I'm sorry to see there is no vga signal. To confirm; you do not get video with a direct connect monitor or in the DRAC virtual console?
Can you check In the DRAC on Configuration > BIOS Settings > Integrated devices screen > Embedded Video Controller is enabled?
NOTE: If the embedded video controller is disabled in BIOS and if you launch the Virtual Console, the Virtual Console Viewer is blank No Signal.
If you have KVM take it out of the equation and direct connect monitor.
Is this known good monitor and cable? Tried a second monitor and cable also ?
Have you tried front and rear onboard VGA ports?
Is this something new that just started? Was it working before and now it does not?
Was anything done recently to the system like adding/removing any hardware? If so, try roll back any hardware changes.
Please let me know how it goes.
