Fingerprint hardware not available

[idkneon]

This problem has been starting some time ago. I used stock firmware and for year everything had good.

I've tried to:

-factory reset

-re-install stock firmware from PC software for Xperia

-custom firmwares

When I intalled custom frimware Fingerprint worked god about a week and than again "Fingerprint hardware not available" (but it works after reboot). 

Right now when I'm goint to Service Menu to Fingerprint test there is a message "Service Menu has stopped".

I'm tired of this problem. So pls somebody help me.

You mean Settings-Support-Xperia Tests? Sometimes I can find Fingerprint sensor in Sensors and sometimes I can't. So sometimes fingerprint can works perfectly but Fingerprint sensor won't be here (Support app), and after reboot (which I have to do because of "Fingerprint hardware not available") Fingerprint sensor becomes visible in Sensors and I can pass it.
