Re-setting Dell 3400MP Projector

  • My friend's projector was password protected and now she can't even get to the main menu.  Does anyone know how to do a hardware factory reset?  The manual says to hold down the "+" and "-" to enter a self diagnostic mode.  Would this enable one to reset the password?  Thanks.

  • My projector has the same problem, call dell and ask for the bill to giveme a master password, and with that in, just do not have the invoice,if your friend has a bill to call dell support and give you the billpassword. and ready when you please pass me the password

  • Hi

    I also had this problem, and Dell support chat help. A password is generated according to the serial number of the equipment.

    good luck
