I'm a firm believer in "if it ain't broke , don't poke".

I forgot to mention 2 points, 1 on each side of the competing procedural
time/costs equation.
I also tapped the 2x 1.5mm holes with 8BA threads for the screws.

there is a silly powered gizmo on the display casing that you'd have to pay
for also . Even then I'm assuming its phenolic ribbon supply has a socket
receiver inside the gizmo, not soldered in place, as its all very thin,
probably fixed in place. If so then replacement full LCD + inverter, many
way, replacement ribbon as well.
