Connect the power at the DC input to simulate the power supply, but first try to locate the schematics, likely you have a short at +B rail. (also check the pcb around the dc-jack positive pin if the jack is directly soldered to the board)

First you need to determine where is the short, remove JP6001 and JP6002 and with a DMM check the resistance at both sides, maybe PD6000 (TVS diode got shorted), you need to isolate parts of the cirtuit to discover the short.

No, he's suggesting you remove the solder at these two points which then reveal a break in the trace and you can test which side has the short with your multimeter.

OHM range or diode testing will do the job.
