I have 2 of these calculators, one working and one with the LCD broken. I've emailed casio several times about a replacement screen over the years. The first time was late 90s early 2000s. And they quoted £25 to repair the calculator, I waited several months and then got in touch again ready to send the calculator to be repaired and pay the fee. Unfortunately, the several months from my fist inquiry until I acted on it was long enough for casio to no longer repair them. I've also asked them several times if any models of a similar age use the same LCD, but they don't have details on such things and no interest in looking I guess.
Does anyone know if there are compatible screens on similar casio calculators? I'd love to revive my old one
