Mac Mini (Late 2012): black screen on boot-up, no cursor

I have a late 2012 Mac Mini. Can't get it to run. I get the chime, then a black screen; NO cursor. Nuttin'. Doesn't get to start-up screen. Just a very faint glow around the edge of screen.

I've tried:

• Booted into Target mode with my laptop and used Disk Utility on it (says everything's fine)

• Totally reinstalled OSX Mavericks on it

• Booted into Safe Mode (didn't work)

• Recovery mode (ditto)

• Opt+Cmd+R+P (nuttin')

Help.

Mac mini, 10.14

Have you tried another monitor?

Another cable/adapter)

Connected the monitor to a different type of output port? (Thunderbolt/mini displayport or HDMI)

I tried hooking it up to my TV with HDMI. Worked fine. Back to Thunderbolt: problem returns. I think I need to have someone look under the hood, no? Thanks so much for your help!

It's a Thunderbolt monitor, so the cable is hard-wired into it. There's no HDMI port on it. I have hooked up the monitor to my MacBook Air. It works fine. I don't have another monitor.

I conclude that either the electrons to the Thunderbolt port failed or the fairue is further up in the chain to the integrated graphics. If that is the case then the HDMI port will not work. If only with the Thunderbolt then the HDMI port should work.

If you have TV with HDMI port try connecting the Mini to the TV.

First try resetting the NVRAM
