It is time to replace the lamp.

will no longer turn on.
The projector can be used for 100 hours after the lamp has reached
the end of its service life.
Replace with a new lamp cartridge.
The lamp cover is open.
The lamp cover is not properly mounted. Mount it properly.
The temperature is abnormally high.
• The temperature protector has been activated. If the room tem-
perature is high, move the projector to a cool place. If the
projector’s internal temperature is high, check the cooling fan’s
ventilation slots and clean them if they are clogged.
• When the temperature protector is activated, the power turns
off and in some cases will not turn back on immediately. In this
case wait about 1 minute, then try again.
The fan has stopped.
Unplug the power cable and contact a store that sells the U4-136/
U4-112/U4-131/U4-111 for repairs.
Should an indicator be in a condition other than normal or flash at a rate other than the aforementioned,
disconnect the power cable and contact your store of purchase.
Thermal Protector
When the temperature inside the projector becomes abnormally high, the STATUS indicator flashes red
(0.5 seconds on/0.5 seconds off), the STANDBY indicator is a steady red, and at the same time the
temperature protector operates and switches off the power of the projector.
Should this happen, please take the following actions.
1. Switch off the power and disconnect the power plug from the wall outlet.
2. Check the following matters and take the required measures.
When the projector is being used in a location that has a high ambient temperature, set it up again in
a cool location. Check the outflow and intake holes and clean them if they are obstructed.
3. Wait about 60 minutes until the temperature of the projector drops.
If after having performed the above matters, the problem still has not been solved, please contact your
store of purchase.
STATUS
The lamp will not light.
Wait at least 1 minute, then turn the power back on. If the
problem persists, unplug the power cord and contact a store
that sells the U4-136/U4-112/U4-131/U4-111 for repairs.
