In a nutshell, sometimes the display will not come off the reel glass.
sooo....remove the fluorescent lamp 1st, remove the three fluorescent nuts
and lamp holder...store aside or let hanging down.
Now remove the two hardest-to-get-at nuts from under the deck for the display panel.
Undo the two black Molex connectors and let hang down.
Break loose the last, easiest nut with a socket screwdriver then remove it with the
other hand protecting the reel glass from smashing into something.
Tilt back the reel glass and remove both the display that's stuck to the reel glass
and the glass at the same time.
The reason why the reel glass sometimes gets stuck to the display is that the display has a rubber-like pad
around the edge and it likes to semi-permanently stick to the reel glass backing.
If you try to pull it off too fast - you'll rip the vinyl right off the back of the reel glass
and it will never look the same again.
Instead you'll have this annoying "bubble" of black forever on one corner.
I've seen sellers selling reel glass that looks like crap because they just ripped apart the display from the glass
and took off some of the vinyl as well....

Once the glass is removed along with the display.
Gently pry the display away from the reel glass backing.
Using a couple of fingertips...press the vinyl against the reel glass while pulling against the display.
Pressing the vinyl against the glass will help you pull off the display without pulling off the backing.
