This guy fixed the Blacked LCD screen problem on Casio fx-3800P

After I completely watch on each steps then I try my own with the

Casio fc-100 Business Consultant that also got the same Blacked LCD screen problem.

I highly recommend to try with other cheap calculators or digital clocks first

for practice. I did successfully did it on a Weather Digital Clock.

My next project will be the HP OmniGo 100 the LCD now totally Blacked this one
will be hard, but I'll try it carefully.

Hint: On the back size of the LCD glass I use regular reflexive aluminum foil tape not perfect but good enough.
