When this happens, turn off power and wait at least 10 seconds before turning on the monitor again. If the INPUT SELECT lamps do not flash, you can use the monitor as normal.

●The self-check function does not work when the setup menu “Remote Active On Standby” is set to “Off” and you turn off the monitor (put the monitor in standby).
