This Projector uses a cooling fan system to keep the unit from overheating. Operation of the cooling fan may produce noise,
This does not affect product performance and is part of normal operation.
CLASSIFICA
TION
STATE MEASURES
Action 1
The cooling fan system is not
operating normally.
If the symptom remains even after disconnecting and then reconnecting
the power cord and turning the projector on again, contact your product
provider or our service center.
Action 2
The projector has changed to
the Cooling mode because the
internal temperature of the pro-
jector has increased beyond
the maintenance limit.
If the internal temperature of the projector has increased beyond the main-
tenance limit, the projector changes to the Cooling mode before turning off
automatically.
Cooling mode: The velocity of the cooling fan is increased and the LED is
automatically switched to <ECO> mode.
Check whether the ventilation hole of the projector is blocked.
Check whether the surrounding temperature of the projector is higher than
the standard temperature range of the projector.
Cool the projector sufficiently and operate it again.
Action 3
The internal temperature of the
projector has risen higher than
the limit, and the projector has
turned off automatically.
Check whether the ventilation hole of the projector is blocked.
Check whether the surrounding temperature of the projector is higher than
the standard temperature range of the projector.
Cool the projector sufficiently and operate it again.
If the same problem occurs continually, contact your product distributor or
service center.
Action 4
The projector turns off abnor-
mally or is turned on within a
short period of time after a shut-
down, or an LED operation
error has occurred.
Turn the power off, wait for a sufficient amount of cooling time and then
turn the power on to operate. If the same problem occurs continually, con-
tact a Samsung service center.
