If the leds on both sensors glow it means they are not faulty. Now point the safety sensors at each other. Connect the white wire from the sensor to the white terminal of the garage door opener and then the black and white wire to the grey terminal. Press the button that closes the garage door on the garage wall or on your remote.

Now that you have made sure there are no obstructions and that both sensors are aligned properly your garage door opener should work. Sometimes the sensor may be beyond repair due to wear and tear and in such a case your best bet is to replace the garage door sensor with a new one. Instead your pre wire is broken and you need to get it replaced. In this case you will set up the level aligned with one sensor then adjust the opposite sensor until the beam of your laser level is hitting the sensor.

Start by inspecting the wires that are going into both of the sensors. If you have a laser level you can use it instead of a string to align your garage door. The latest garage door sensors are technologically advanced and even allow you to control the opening and closing through an app on your smartphone.
