Garage Door sensor eye problem

Garage door won't close because of a sensor problem. Online guide says if light on main unit flashes 4 times, this is the error: "Safety Sensors slightly mis-aligned. Re-align receiving eye sensor or clean lens". It's a Raynor Pilot, dual car garage with matching openers. Installed circa 2003.

The sending unit seems to work fine (steady orange LED). The receiving unit however has a flaky LED. It's dim (dimmer than the other receiving unit on the other garage door), and I can't get it to go brighter, no matter how I try to point it at the other sensor. In fact, it's just staying off now. There has been no activity that I can tell that is causing this (bumped, etc), and the brackets that they are attached to are very sturdy.
So, do I need to replace the sensors? Seems like photo-eye sensors go bad often, but I'm not sure. It's only a $30 venture if that's the case.
