Mac mini (late 2014) does not boot, only turn on white led in the front, no chime
The last week I was updating my Mac mini with a system software update, don't remember what was it for, and at some point there was a power cut before the update finished. After that, when I turn on the Mac mini, it turns on the white led, but there is no chime and there is no signal in the monitor. I have an Apple wired keyboard and a Black Mamba wired optical mouse, please help!, any suggestion will be appreciated.
Mac mini, macOS High Sierra (10.13.6)
