Cautions: Disconnect the AC Power prior to making any disconnection or connection.
If the power LED continues to blink even after the TV is unplugged, press and hold the power switch on the TV for a few
seconds until the LED turns off.
When taking voltage reading, place the voltmeter probe at the test point, component, or connector’s pin indicated before
connecting the TV to the AC line. This will ensure voltage reading accuracy before the TV shuts down. (Since the TV is
shutting down, expect the voltage to only come up a couple of seconds.)
