The factory default password is to hold down the number button and press 1793 on the remote control
did you try it?

Sorry to bump this year old topic, but... I come with good news;

I managed to get ahold of such projector for 30 EUR second hand. Came without a remote. So I used a Logitech Harmony 300 to mimic it's movements (USE profile Epson EMP-822H) because the correct one does not have the button bindings for 0-9 keys !

When the projector was connected to the mains outlet, the standby LED was on. And shorted the two pins RST-PW a few times. Maybe later on i've turned on the projector while 'running' and did the same. I recommend to try the 'passive' power mode for the reset first.

The beamer went in panic mode, because of the lamp-cover sensor which did not register as closed, while the complete top was off of it. It runs without the cover, the almost 'dummy' keypad in the top cover was not needed to operate the projector.

Also managed to connect it trough a lan cable, and manage it by "epson projector management ver 5.20" however not much was interesting to change of modify.

Forgot to mention, once the projector is turned on without the coversensor of the lamp engaged; it will not start properly. You will need to turn it off fully, engage the little switch (so that it is shorting) and you can run the projector topless. For the reset purpose.

After the reset the code 1793 was accepted into the projector and the boot logo and warning will remain each time you will power it up. I have not succeeded to either change or remove the security features. As I suspect these are part of the firmware. As you'll need the remote anyhow to turn it on, the four digits passcode (1793) are not that big of a problem.

For me it was the absolute thrill to get this thing back to operation again, otherwise it would be e-waste. And 10.000 views in this topics shows, that more people will be able to repurpose old electronics that otherwise would go into the landfills. Here in The Netherlands you literally drown in the ultrashort throw projectors from epson. As they get scrapped from educational and medical industries after certain years of use, and go for almost little to nothing second hand.

Also thanks to the other contributors in this topic regarding the discovery of the reset feature.
