No power on, no charge, black screen

Hey guys! Before nothing, thanks for your help. Have a Samsung Galaxy S9+, these become my hands, and not power on, not charge and no display on screen.

When I plugged the cable into charger port the power consumption is 5 volts and 0,07 amps, but no charge. The battery should be in 3,85 volts but this have 1,54 volts, this point make me think the port charger is broken, but I will like first confirm this.

Someone can help me or will say, ¿how can resolve the points?

Thanks!
