Light will not turn off with garage door opener?

You open the door with the opener and the door opens. And the light comes on. both have 3 buttons on them. Then you push the button to turn off the light and it stays on. but you can close the door with the opener. So I tried the other opener as well. Same problem with both. Light stays on till you walk to the far side of the garage and use the manual shut off. Hard wired for the light. So can you replace the sensor for the light in a garage door opener. As I assume that is were the problem is as both openers do the same thing starting today. Every thing else works but the light shut off. I know there is a circuit board in the garage door opener box on the ceiling as well. But have never worked on one. Or is it even worth taking down and trying a repair. And just use the hard wired light shut off from now on.
