    check 5V on pin#11 and 12..and also check short circuit on PLM2 with ground....also check +B voltage on the Drain (PIN5) on PQM1 if all are OK replace ic RT8207 with working one and check the result.....

                    Low resistance on CPU VCore is normal. You should rather check if you get voltage on CPU VCore…
