Need help to trubleshoot my zero

hello everyone, I’m having some truble with my radxa zero, yesterday i was using it and suddenly it stopped working.

when i unplugged it from the power the board was hot,so i waited the board cooldown, then i tried to power on again,the green light blink one time with low intensity and did not got boot, also the board start to heat again.

tried to rewrite my 2 SD cards with ubuntu and dietpi none of them worked for me.
