The electrical power cord is unplugged.
Connect the power cord correctly.
The main power source was interrupted (for example
a power outage (blackout), etc.).
Disconnect the power plug from the power outlet, and
allow the projector to cool down at least 10 minutes, then
turn the power on again.
Either there is no lamp and/or lamp cover, or one of
these has not been securely fastened.
Turn the power off and disconnect the power plug from
the power outlet, and allow the projector to cool down
at least 45 minutes. After the projector has cooled down
sufficiently, verify the lamp and lamp cover are securely
attached, and then turn the power on again.
The signal cables are not correctly connected.
Correctly connect the connection cables.
Signal source does not correctly work.
Set up the signal source device correctly by referring to
the source device manual.
The input changeover settings are mismatched.
Select the input signal, and correct the settings.
AV MUTE function is working.
Press AV MUTE button on the remote control.
The USB TYPE B port is the selected picture input
source even if MOUSE is selected for USB TYPE B.
Set USB TYPE B to USB DISPLAY in the OPTION menu
to project the picture input to the port. Otherwise select a
different port for picture input.
The USB TYPE B port is not recognized as an input
port because of electrical noise.
Temporarily set USB TYPE B to MOUSE in the OPTION
menu, and then change it back to USB DISPLAY, so the
projector recognizes the USB TYPE B port as an input
port.
