Temperamental garage door

Starting a couple of weeks ago, our automatic garage door sometimes goes down about 1/5 of the way and then goes back up.

There aren't any visible obstructions, and there doesn't seem to be an obstruction sensor anyway (the garage door was installed when the house was built, and that was before such sensors became mandatory). The problem only happens roughly half the time we close the garage door (needless to say, regardless of whether operating it from the button inside the garage or from a remote control) and seems random (day or night, hot or cold weather, etc.). When it happens, the only way we can get it down (aside from multiple re-tries) is to stop it when it's going back up and then from that not-all-the-way-up position command it to go back down again. For some reason, if it's not going down from its fully up position, it never fails to go all the way down. Any ideas what could be causing this and how to fix it?
Note that I read this similar thread
but the difference is in that situation the door was going all the way down and then back up, whereas ours is just going down about 1/5 of the way before it goes back up. Looking at the answers in that thread, that seems to be a significantly different type of situation.
