HP42S with bad LCD

[Geoff Quickfall]

I second Didier’s recommendations!

Make sure the zebra strips and the PCA and LCD contact points are CLEAN! Otherwise you will have LCD segment dropouts.

Also, when releasing the tabs to gain access, they do fatigue so you do not have unlimited attempts to get the connections on the LCD working to perfection.

Done this on the 48GX, replacing the blue with black LCD panels.


Cheers, Geoff

Didier, any more work on the PC-1300s now that you have the manual in English?

Will be presenting more on that at HHC2024.

Cheers, Geoff
