"Err 1" is a loss of tachometer signal. Does it clear when you plug it back in? Can you manually release the lid? The release is located on the underside of the machine, at the front right corner. It's a small plastic plug in the base - pry it out, and pull the cord until the lid releases. If you've had trouble closing in the past you may have to push down on the lid before pulling the cord, as it sounds like your latch isn't properly adjusted and is too tight, or possibly the switch is damaged, faulty, or loose. If you get a normal display with the power cord plugged back in, and with the lid open, spin the rotor by hand to see if you get a speed reading. If you don't, there's a tach issue.

So, you popped out the the white plastic plug with a screwdriver and there was no cord looped through the eye?

Bummer. The cord must be loose inside. How about the lid release key, does it not open the lid with the error reset? If the lid is jammed you might have to press it down first before pushing the button. Otherwise you'll have to fish around with a paper clip or something to try to hook the cord out. Beyond that, you'll have to cut a hole in the front cover.

I have a similar problem, and yes, I do have the model that you posted an image of.
