How do I repair failed sensors?

[Android Central Question]

My S5 screen has stopped rotating and my pedometer doesn't register any steps. I have tried advice usually given on the net. Sensor tests failed. How do I repair this, which part do I need? The phone is not under any warranty.

Welcome to Android Central! Here's an article showing where the sensors are: https://news.samsung.com/global/10-sensors-of-galaxy-s5-heart-rate-finger-scanner-and-more. But I'd guess that replacing them would not be simple, since they're likely soldered into place. It'd probably be easier replacing the whole motherboard.
