If you go into that thread, there's a gentlemen in Brazil who repairs HP calculators.

Take a look at his "before and after" pictures with center spots on the displays of a 42S and a 32SII that look similar to that on your 19BII:

Excellent and thanks for the information. I think the arrangement would be more expensive than what I paid for the calculator. But if this person fixes the displays, I wonder what methods can be used for that, and do it yourself as a learning and so the cost of repair is not so high?
