Part No: 5C10Z23917

Camera,HD-IR,Front,2MIC,ZIF,Azw
Part No: 5C20W42992
Substitutes: 5C20W42993 and 5C20W42994

And it says exactly what you posted SC20F27116 (for 5C20W42993), so it's an IR webcam, on the regular 720p cameras if i select only 20TD the number on the sticker is completely different

You can click on the images on the lenovo parts site and check

The serial number is: PF3JCYGJ (i had written above... ) again it shows 2 camera suitable for that laptop as a replacement .

They're equivalent, both IR, listed as substitutes for each other, the LCD cable is the same 5C10Z23917

Likely they grab whatever supplier they got cheaper for a given batch

EDIT: Go figure, I just got an ebay ad on this forum (browsing from my phone) for "EDP Screen Cable+RGB Camera IR Cable DC02C00MF10 for Lenovo ThinkPad E15 Gen2" Coincidence?

Yes , the day has come.

Yes, the cable arrived , yes i changed it, also i changed the fuse just to be sure, and just to be sure the FPC connector. The laptop doesn't anymore shows signs of ground beeping ,and it can power on with charger connected and ,screen cable connected.
I cannot believe that the cable was the problem that didn't allow it to turn on.

But!

The laptop still shows in external screen but internal screen doesn't . But the new let's say symptom is that the screen flickrs like it tries to show something ,for 0.000001ms it does like a flash from black to backlight black but again still remains the same.

I did update the BIOS to the latest one to be sure, again same nothing changed....

I have given up.

Does the screen show an image if you shine a flashlight to it?

EDIT: Now we have to figure out what prompted your customer to replace the LCD cable in the first place, so I think the original fault is what you have now
