Seems like quite generic quad ESD protection device. Something similar to IP4220CZ6. There is no need to find exact part, there are more than a hundred of compatible parts. You can desolder it and see if the thing starts working as this part is inactive during normal operation. If it does not work, there is more damage to it.
