Hello, having a ASUS Z390-E, from ebay (damaged)

the board is dead, no leds. It poweres on, supplies some voltages (as in the attached picture) but nothing else. CPU fan spins. I replaced a regulator, that supplied 3.7 instead on 3.3 (chip range 3-3.7).

It shows some work sign on chipset, someone heated it (wasn't me)

Can someone with experience please advise?

bios was checked, it has latest version, bit by bit compare OK.
