1.7.3 C265 PSB/PSE Board
There are two types of the C265 power supply board as listed below.
C265 PSB board:For America, Japan, part of South east Asia
C265 PSE board:The rest of all regions
The C265 PSB/PSE board uses the switching regulator system. Since
the C265 PSB/PSE board uses the power switch on the secondary side,
it keeps applying voltage to the primary side across the T1. Especially,
the heat sink to which the Q1 is attached can not be insulated due to the
circuit’s formation. Therefore, to avoid an electrical shock, be careful not
to touch the heat sink and other metallic parts simultaneously while
troubleshooting.

W A R N I N G
Never touch the heat sink (radiation plate) on the Q1
with your bare hands as it is not insulated. Otherwise,
you will get an electrical shock.
