Hello, I have recently came back to cycling and riding again after almost a year, to which my bicycle was just sitting around the garage during the whole time. After changing my cyclocomputer's batteries, it seems to be not reading the riding parameters anymore. Now, before I change it and buy another one, I was asking is if there is any other way to troubleshoot this problem, so as not to waste any money.

So far, I have done:
1. Recalibrating,
2. Readjusting the magnet to the sensors,
3. and also wiping the sensor and magnet itself from dirt, etc.

Btw, the computer itself seems to be running fine after changing its batteries, buttons are responsive, display is fine, etc. Any answer will be greatly appreciated!
