You're totally right Royce!
Even if those ribs in figure 13 can be released, I'm not certain if the hinge releases too.
I was thinking that if the bottom of the door could detach, then that might allow it to loosen downward and let the tape get out from the heads.
Ok cool I'll try it outThe top is part of the front panel you kind of lift it up and forward the door should release by itself don't force it. I repaired one of these recently its a killer box.
