after watching your video, you mentioned your safety eyes were ok, is the led light on each lit and glowing steady? If they are, and you are getting the same click response from your wall station button, the lightning might have fried the circuit board inside the opener head. I wouldn't worry about where the trolley stopped in relation to the other door, that's just a matter of where the limit control is set. Also, you won't be able to move the chain by hand like you mentioned. Gear types in the opener head prevent freewheeling. How old is your opener?
