How to fix a BenQ MS521 that does not turn on?
- RRickey ElliottJul 26, 2025
If your BenQ projector does not turn on, ensure the power cord is securely plugged into both the projector's AC inlet and a working power outlet, and that the power outlet switch is on. Also, if the projector was recently turned off, wait for the cooling process to complete before attempting to turn it on again.
