If the Projector appears to turn off by itself, try disabling some of the Projector's energy efficiency functions.
1. See if Sleep Timer has been enabled. The Sleep Timer automatically turns the Projector off after a specified period of time. Go to “Setting” > “System” > “Power & Energy” > “Power” > “Sleep Timer”.
2. If the Sleep Timer has not been enabled, see if Auto Power Off or Off Timer has been enabled and disable it. Go to “Setting” > “System” > “Power & Energy” > “Timer” > “Power Off Timer Type” & “Auto Power Off Time”,
Go to “Setting” > “System” > “Power & Energy” > “Power” > “Switch Off Timer”.
