My steam deck up directional button is not given any input or not working at all. My other buttons on my steam deck does including the left, down, and right d pad inputs. I took it apart to see what was wrong with it I can't seem to brainstorm what's going on as everything looks normal inside. So what I need a new membrane Dpad or the entire left bumper board with the d-pad cable?

I had the similar issue so here is the solution log
Issue:
Steam Deck D-Pad "Up" button stopped working. Instead, the Steam and Quick Access ("...") buttons acted as if the "Up" direction was being constantly pressed. Problem persisted even in BIOS, so not OS-related.
Symptoms:
Fix (worked for me):
Theory:
It might not have been a physical connection issue. The BIOS input controller may have glitched and started misinterpreting D-Pad input — causing "phantom presses" and remapping behavior. Disconnecting/reconnecting the ribbon cable likely forced a soft reset of the controller's state. So the root cause may be firmware-related, not hardware failure.
Conclusion:
Bad input state or firmware glitch caused phantom input. Simply reseating the D-Pad cable forced the controller to reset. No need for cleaning — just unplug–replug.
Hope this helps someone avoid replacing half their Deck.

Thanks a lot! Worked for me
Yup, re-attaching the D-Pad cable did the trick. No need to turn the SD inbetween the processes, it registered that action naturally.
Thank you so much! That solved my problem perfectly.
Had a similar issue, but it was down and left that weren’t working. It would also randomly turn on the screen reader. Regardless of the differences, this fixed it. Thank you so much!

I had this on my D-pad cable:
I couldn't find this with the naked eye, after inspecting everything I tried using a magnifying glass, and voila - I found it.
What worked for me was cleaning the space between contacts with a needle.
