If you don’t know the password, do not continue to enter the incorrect password. If you enter the password incorrectly three times in succession, the projector’s operation is locked and you’ll need to disconnect the power cord, then reconnect it to redisplay the password screen. If you enter an incorrect password 30 times in succession, the projector will be locked and you’ll need to speak to an Epson support representative for repair options. (See Where To Get Help.)
If you enabled the password before you set one and you see the prompt to enter the password, enter the default password 0000 to proceed.
If you set a password and then enabled it, but have now forgotten it, you'll need to contact Epson. (See Where To Get Help.)
