This specimen had poor LCD contrast.
The issue was fixed after cleaning the battery holder connection pads on the PCA.

I know this was a while ago, but i must thank you very much for the great pictures of the FX-4000P
internals!
It helped me a lot now when i needed to take it apart, and then to get it back again!

edit: hmm, why do i always type FX-4000P, when its fx-4000P ?
