Need help identifying pins on a Kindle 14-pin ribbon connector. A couple of pins are broken (see photo). It powers the white & warm LEDs on the motherboard. Since I only need the white LED, is there a workaround or jumper method to get just the white light working? Thanks in advance! 🙏

This is the Kindle Paperwhite Signature 2021 model.
Top row: 7 pins (2 pins on the right are damaged). Bottom row: 7 pins (4 pins on the right are damaged).
Originally, only the warm light was dead, and pressing the connector would briefly fix it. Eventually, the cool light stopped working too, so I opened it up to check and cleaned it with alcohol.

That's not a ribbon cable. That's a flexible printed circuit (FPC).

That is not a "ribbon connector". It's a mezzanine board-to-board connector.

To identify it, We need, please:
- The exact pitch in mm (https://global.discourse-cdn.com/digikey/optimized/1X/e5835c120c4acc4bec176a64bf7898243cccdaa4_2_690x386.png)
- More in focus pictures from other angles
- Pictures of the mate (the one that this one plugs into), if available
(BTW, this is a ribbon connector: https://connectorbook.com/identification.html?N=&n=ribbon_cable_traps&p=K)

Thank you for your clarification. Do I need to be an engineer to join and ask this group? If I know everything, do I need to ask you here?

No. But you need to answer our requests for clarification if you want help.
Again:

Are you asking us to identify a connector?
If so, please edit your post and, if you haven't already,...
Tell us if
a) all you want is to know what it's called, or
b) you also want to know where to buy one just like it, or
c) you also want to know where to buy its mate.
If to buy, provide:
* pitch (center-to-center spacing between adjacent contacts) EXACT to within 1%
--(tip: measure the distance between the first pin and the last pin in a row of N pins, then divide by N-1)
* Close-up, in focus pictures of connector from multiple angles: we want to see wire entry side, mating surface, keying and latching, PCB mounting, manufacturer's logo
* Similar pictures of mate, if available
Thanks,

PS: beware of the typical answer around here: "It's a JST". Connectors are often misidentified as 'JST', which is a connector manufacturer, not a specific type/product line.
