If the projector is shutting down after 15 minutes it could be either a lamp or a temp issue. You should look to see if either the lamp or temp LEDs are coming on on the projector after it shuts off. If it is a lamp LED you will need a new lamp. If it is a temp issue it could be a fan failure that would require service.
To get your projector serviced or for additional help, please contact our customer service team at 888-289-6786.
