Joshua --
These Pioneer-series calculators are not really desgned to be repaired, but it can be done. Here are several contributions from the Articles Forum on this website:

I should mention that, even after being discontinued in 2002, the HP-20S is still plentiful and readily-available from eBay and other sources, for a reasonable price.

And if you find it not repairable, the Hp33s algebraic mode is AOS just like the Hp20s. Therefore the Hp33s is the closest direct replacement for the older Hp20s also.

Thank you for your replay, I don't like the hp's style of current model . I like the old model such as hp22s , hp20s , hp 12c , hp15c. I prefer repair my hp20s .
