Abnormal Operation
Power/Remote Control Errors
I cannot turn on the Projector.
• Please make sure your projector power plug is correctly connected to the outlet.
•
If you are using a multi-outlet, check if it is working properly. To check whether a
power strip is working properly, plug the projector's power plug directly to a wall
outlet and observe its operation.
• Try to power on using the button on your projector set.
The screen does not appear for some time after power-on.
•
This is because there is a noise-removal process to eliminate any possible noise
that may appear during power-on. This does not mean the product is defective.
I cannot turn the projector on with the remote control.
• Please make sure your projector power plug is correctly connected to the outlet.
•
Replace the batteries in the remote control. (Use alkaline batteries.)
• Check whether there are any obstacles in front of the projector's remote control
sensor. Sound bars or other obstacles placed in front of the projector's lower
receiver may obstruct IR signal reception.
