There Siglent, fixed it for you
Sorry late to the party and yes that will fix it.

I've only seen the one do this continual reboot, a unit just a few days old that we immediately replaced.
It's the small circular diode bridge failure < replace it = fixed.
For years they used these little circular bridges and seem to not have given any trouble until recently however now I believe a HW mod has upgraded to a better bridge from one of these little critters.

Liking the chunky replacement you did.

Others that find this, within 3 years of purchase it's a warranty issue.
