A reset can reboot your product or it can clear all product settings and revert your product to its original out-of-box state.  If you encounter issues like automatic shutdown & reboot, frozen on TCL SmartProjector logo, or colorful lines, please try to factory reset the projector.

To Restore to the Factory Default Settings:

Go to Settings > System > About > Reset

Note: This will reset everything, erasing all downloads, passwords and log ins.
