# System reset

A system reset can resolve persistent issues that other troubleshooting steps haven't fixed. Follow these steps to reset your Lü correctly:

 

**1. Turn off the computer and the projector.**

**2. Find the breaker on which Lü is installed and turn it off for 2 minutes.**

![](https://help.play-lu.com/hubfs/Knowledge%20Base%20Import/lights-Apr-20-2026-03-53-59-0047-PM.png)We recommend identify the breaker if it's not done already.

 

**3. When the breaker is back on, turn the projector on again. The computer will automatically reboot.**

It's very important to turn off the computer and the projector before turning off the electrical breaker to prevent any damage to the devices.
