I remove two panel underneath the steering column. The first panel is removed using a 10 mm socket. The second panel is removed using a torx socket (can't remember the size). Removing these two panels gives you room to get to the clip on speedomter. Looking at the speedometer, you should see two rectangular holes on each side of the speedometer cover. I use a awl to push in the clip (you could use a screwdriver). Looking underneath the dash, you should be able to see the clip you are pushing on with the awl. I take my 2nd awl and put it behind the clip. I get the left side to release. One the speedometer cover releases, you can see the speedometer. You will see the 4 torx screws (t20) and two smaller clips holding the speedometer. All that is left is the wiring. (I take a sharpie pen and mark one of my wire locations on the speedometer. I am not sure what it does. It is a single wire.)

The transistors are BST80, the numbers are just SMD codes, but the reason to make transistor to fail is the illumination layer is faulty. There is also a transformer which may have open circuit You should check that either

On the inside trim, you can remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge.
