are locked and do not work, but the projector can be controlled using the remote control unit.
Is the temperature inside the projector too high? When the inside temperature is too high, the
protective function does not allow your projector to be turned on. Wait some time and then turn it on.
Check to see if the connected input has been selected.
Check to see if a cable is properly connected to the input terminal.

warm place after storage in a cold place, the lens and other optical components inside may
develop condensation. In such a case, please wait several minutes until the comdensation
disappears.
Check whether the signal cable connected to the projector is disconnected.
