Nothing is visible in the pic attached. Did you measured the other end of resistor connected to pin5 of charging IC?? Want to be sure about the status of +3V LDO first. Trace the resistor connected to AD_ID pin of dc jack and measure resistance as well as voltage on both sides of them. Usually 2 resistors are connected to AD_ID pin and they act like voltage divider. Measure voltage on AD_ID pin of SIO also. Which SIO is used here?
