RE: Dark patch growing in LCD screen
The fix would require opening the calculator up and replacing the reflective backing on the LCD. There is a thread covering this process for a HP-22S: https://www.hpmuseum.org/forum/thread-12652.html
An alternative would be to replace the entire LCD module using a HP-17B or HP-17BII (but not a HP-17BII+) as a donor. (I'm not sure about the 17BII+, but since it is a reimplementation of the HP-17BII, I'm guessing the LCD module would be different.) — Ian Abbott |
