Understanding the Warning Lamp Flash Patterns

When an internal problem occurs, the WARNING lamp on the Control Panel flashes red.

When dealing with the problem, turn off the projector, wait until the cooling fan stops, remove the power plug from the AC outlet.

Flash Pattern

Meaning

Countermeasure

 

 

 

One flash

Abnormal

The temperature inside the projector is too high for

 

temperature

some reason or the outside air temperature is higher

 

 

than the specified one.

 

 

If the problem is inside the projector, check whether

 

 

the projector is installed and operated normally, turn

 

 

off the projector to cool its inside, and retry projection.

 

 

If the same warning occurs again, the projector may

 

 

be defective. Contact your dealer.

 

 

 

Two flashes

Faulty lamp

The lamp has burnt out. Replace the lamp with a new

 

 

one. If the same warning occurs again, the lamp drive

 

 

circuit may be defective. Contact your dealer.

 

 

 

Three flashes

Faulty lamp

The lamp cover is open. Check whether the lamp

 

cover

cover is installed properly. If it is installed properly, the

 

 

lamp cover detection switch may be defective. Contact

 

 

your dealer.

 

 

 

Four flashes

Faulty

The cooling fan or another component may be

 

cooling fan

defective. Contact your dealer.

 

 

 

Five flashes

Faulty power

The voltage of part of the power supply is abnormally

 

supply

high or any other problem has occurred in the power

 

 

supply. Contact your dealer.
