PowerEdge T610 won't post but has no errors

I have a PowerEdge T610 that I bought in 2010.  I ran ESXi on it for several years (until 2014) with no problems.  I then powered it off and stored it (climate controlled) for a few years and fired it back up in 2017.  ESXi started, my VMs were all just as I left them, all was good.

I used it for a couple months and then shut it down again.  I am now attempting to start it back up but it seems that it will not post.  The power supply LED is green.  The power button light is green.  The fans are running.  The front panel LCD display simply shows my service tag number.  The menu buttons under the display work fine and it still knows its IP address, hostname, etc.  I get no beeps, no change to the LCD saying "booting" and no signal to the VGA display.

After reading a number of other posts I tried reseating the power supply, the memory, and the hard drives.  I also removed a PCI NIC that I wasn't using.  There appears to be no change.  I'm not sure what else to try and am really confused that the LCD display doesn't have any errors on it.  Thanks in advance for any information or suggestions.
