Hd20 flashes green but wont come on.

When I push the power button the light flashes green, the fans cycle on and off but the bulb does not come on.  I made the mistake of blowing off the side vents while it was on and since then it wont come on. I assumed i blew the bulb so I got a new one, that didnt work so I got another one. So im pretty sure its not the bulb, as i have tried 4 in it.  Please help.

    Hi JpHilgner,

    Thank you for posting on the Support Community.

    With regard to the issue raised, when you start the projector and turn this on, do you notice a sequence to the LEDs?
    For example, the Power LED may flash 7 times, before pausing and repeating this sequence until eventually the projector powers down.

    Can you also help to confirm the model number of the projector?

    Kind regards,
