@sayefwasif Permanent missing lines on the screen (instead of random garbage like mine) could mean that the other flex cable is bad, the one from the LCD controller chip to the glass screen itself. Check the solder joints on that one or try pressing the flex in certain spots and see if the missing lines come back.
I have one of the from when i was at Uni, powered it up recently, works fine thank goodness, cost me £70 new :o) Can't remember how to bloody use it though lol wow, great fix, I want mine to go wrong now so I can do that lolol
What's the buttom combination for the self test? :o)
hurray! You saved the calculator from being tossed! If there is anything to learn from the video, it is that with a little tender loving care, some items can be fixed!
how did you get the display test eg all pixels on, all pixels off? Btw, the self-test worked my screen works like new!

Nice repair. What would be the cause of an LCD showing part of a digit? Would it be an easy fix?

@sayefwasif Does the calculator seem to work fine aside from the screen issues?

I would have done two things differently, I think.
1) I would have added some gentle heat to the flatflex to make it come loose easier.
2) I think I would have used ribbon cable to replace the data wires.
