Can TouchID buttons be replaced without replacing the entire board?
Palmrests for these units are being sold without the TouchID / power button on the far right end of the touchbar.
The TouchID button has a small integrated flex/ribbon cable (labeled "00920-A") that then plugs into a secondary flex/ribbon that extends the original and changes its plug type so it can connect to the logic board under the headphone jack ribbon. That extender cable is labeled with "821-00645-A // MFC0517" and I've been able to find them for sale, but I can't find replacement TouchID sensor anywhere.
Powerbookmedic's listing for the palmrest claimed that the TouchID sensor is not included with the palmrest as they are "married to the logic board". Does that mean that if the TouchID sensor/button is damaged or if its cable is ripped, the ENTIRE LOGIC BOARD needs to be replaced?
Please, somebody, tell me that this isn't true.
