But when I press ENTER the calculator turns off. After a few minutes it appears on. The blackout occurs the same if I do sin, cos, tan or even LOG, gold key, etc. operations. It seems to turn off only with the top keys. It seems like it can't perform stack operations. The ALPHA, PRGM and USER keys work.Hi there, did you try the test which Robert Prosperi suggest you, I mean "pressing firmly/gently on the two outer rails, between the top two rows of keys, to press the buttons for your testing while maintaining the pressure"? Yes, indeed. I did the test as I understood it, without opening it, pressing in the space between the upper keys, pressing firmly. And the calculator behaved the same. I understand that the test is to check the tenacity of the posts. But I must say with regret that nothing happened. It's a shame, because this is my first 41 |
