Hi there:

Garage door won't come down and the light blinks 10x. If I let go of the button the door goes back up. I have to hold the button until the door closes all the way to get it down. On the light sensors near the floor. One of them is green and the other one is yellow? Not sure if that's a prob.

The sensors are supposed to be green and yellow.
They are most likely out of alignment. Check and see if the green light is blinking,you have to look closely. If it is move it slightly so you have a steady green light.
