I wonder is this might be due to a leaking capacitor?

 

Have you explored it to see if there is some way to remove the discoloration?

 

No, there is no capacitor to leak on this board. The problem is eink display reaches the end of life. However, the capacitive touch layer is still working that's why you can still control the function keys despite the blur eink screen.

 

The F1... symbols are from eink layer, the metallic semi reflective layer is the capacitive touch sensor.

FWIW I opened the lid on my X1C2. There's no sign of discoloration on the plastic strip. Perhaps there was a manufacturing defect in some production batches?

Likely and probable.

 

On another note just a general rant. My CX! 2nd gen touch screen started going nuts (ghost clicks) so I removed the said cable. Touchscreen gone but at least I can use laptop. Screen developed 3-4 small dead pixels. Still quite useable.

 

Next adaptive keys discolored badly and progressing.

 

Most recently the nonfunctional key row.

 

The realistic way to replace these parts is buying a used donor CX12 but I don't think it is worth throwing much more money into this. I ordered a 40 dollar new keyboard as they are still available. The seller has sold many already which suggests common issue for keyboard to fail.

 

Though I'm not a apple fanboy but my 2011 macbook pro used daily is still rock solid. no issues, screen like new. 4.5 lbs though as opposed to CX1 3
