The technician verified customer complaint of a burning smell.
Unit was picked up and a small rattling noise was heard.
Burning smell was observed with the unit fully assembled.
No attempts were made to power on the device.
Unit was disassembled and when the rear housing was removed, a small piece of ferrite was found loose inside the unit.
Ferrite was broken off of the ac/dc l1 inductor.
Further disassembly found that the burning smell was due to a piece of the broken ferrite becoming wedged between the dc/dc pcba and the chassis, causing a short.
Burn marks were found on the chassis and the dc/dc pcba.
Both ac/dc and dc/dc pcbas were removed.
If information is provided in the future, a supplemental report will be issued.
