Orange Pi Zero 2 It does not turn on

nept1

Good morning.  I have had an Orange Pi Zero 2 since February of this year and it has been working correctly for me.  Last week I had to turn it off (via ssh with the shutdown now command) and now that I want to turn it back on it doesn't do anything, it just turns on the ethernet lights.  The cable, the card and everything are as before, but it does not show an image or turn on the LED or anything.  Could you help me?  Thank you.
