What to do if the internal temperature is rising in my ViewSonic PJL3211 Projector?
- BBrandon MillerAug 11, 2025
If the internal temperature of your ViewSonic Projector is rising, immediately turn the power off and let the projector cool down for at least 20 minutes. Then, check for any blockage of the air passage, if the air filter is dirty, and if the surrounding temperature is above 35°C. If the issue persists, set the FAN SPEED in the SERVICE item of the OPTION menu to HIGH.
