If your VANKYO projector can’t power on or shut off instantly, you can check the following items.
Check whether the power plug is working and firmly fitted in the outlet.
If the power indicator lights on but the fan doesn’t work, please contact the seller for assistance.
Overheating of the VANKYO projector will activate the built-in power-off protection panel. Restart the projector when the projector gets cooler.
Overload of power when a USB flash drive of 1TB or above is connected without an external power supply will cause shutting off. Insert the flash drive when the projector is powered off or provide an external power supply for the flash drive would solve the issue.
If all the items above don’t help, please contact VANKYO Support.
