This is partly correct. You can replace the touch id sensor, but you will lose the ability to use the fingerprint. I think it depends on if you encrypted your disk if you might be able to just reinstall it, but I have not read that you cannot do it, just that fingerprint unlock is not possible. There is a specific chip in it that binds it to the board. With the right equipment you could perhaps transfer it, but that is high level skill - check out Rewa if you’re interested, they do that for some parts and have videos. It's something I personally skip on - and on Apple products all together because of the horrors of repairing them. If indeed the board does not work at all without the flex cable, then the cable has the chip on it. Since I have seen these boards boot without it attached, I cannot imagine it will not work at all, but if that is the case, please be very specific in the how and why before you claim it. Thank you.

Thanks for replying. Not sure if I can relate that picture to an iBook? I think it is no cable problem, I switched it already, same white screen. When I take the cable there is a slight difference. So it seems the image data is not transmitted properly through the cable. I checked the connector, but it seems fine. So either it is not or it is a logicboard issue I guess? Someone here has the same, no fix though. http://discussions.apple.com/thread.jspa... Does anyone know a solution?

Did any1 find a solution? I have the same,internal screen blank,external screen ok. Changing screen and cable did not help. Any1 knows what causes this? Pressing video chip did not help

Hi,

Does anyone happen to know the values of the L2 and L3 parts on this DC-in board?

I am looking to reuse them but I cannot find any specs.

Thank you and regards,

Vincent
