Liftmaster RSL12U Gate Stuck in "Open"

Hi all. Bought a house with a sliding Liftmaster RSL12U Gate. The gate has been working fine for 3 months, but I just got home from a trip to find that the gate is stuck open and can't be closed with remotes, keypads, or using the gate control itself. I'm attaching pictures of the gate control board. The "open" light stays lit no matter what I do. I can use the reset button to manually close the gate. After I manually close it, then any button press will return the gate to the "open" position.

It seems like the gate is being held open by some kind of input to the board that I can't detect. As for other inputs, all I have is a photosensor, which seems to be working. I've tried resetting the board, resetting and reconnecting all remotes, and checking for obstructions. Are there any gate specialists out there who could suggest what else might be causing the "open" light to stay lit and prevent any other inputs? Many thanks!
