Your Projector Does Not Turn On
8 out of 10 times it’s a lamp issue :
If the projector senses an issue with the lamp it wont fire up. Again, did you recently replace the lamp and if so does your projector need you to reset the lamp timer? See owners manual. However there have been a lot of fake lamps on the internet (mostly Amazon marketplace.) They are a fraction of the normal cost. They also usually fail after about 2 months and they often destroy the projector.
power supply issue :
The unit has a power supply issue or it’s not getting power from the power source.
Make sure all covers and latches are closed :
If you recently installed a lamp, make sure all covers are closed. The projectors have safety features that prevent it from powering on if it detects that a latch is open.
