What to do if Canon LV-S1U does not light?
- SSherri StaffordAug 9, 2025
If your Canon Projector doesn't light, first ensure the power cord is properly connected and the Lamp Replacement cover is closed. If that doesn't work, open the projector's top cabinet and check if the Thermal Switch is open. If it is, reset (press) the Thermal Switch. Also, check if the Fuse in the power unit is open. If the Thermal Switch is activated due to increasing temperature inside the projector, investigate the cause of the temperature increase, such as a clogged air filter or a malfunctioning fan.
