Hi all,
Ive got a frontlit sp that has decided the light is optional. I just need a bit of guidance on what to test. I think the pins on the back of the pad are voltage for the frontlit. I know a pin on the ribbon is responsible but not which one.
The tactile buttons have been dying out slowly so I need to test that one too.

Does the pins on the screen ribbon send power and button signal?

Hmm. Light seems to be working again. May have just been some dirt or a bad cable seat
