You didn't happen to have replaced any light bulbs recently did you?
Rick, K9AO
I have not replaced anything in the house for a while, no new electronics, nothing new at all.
This is very strange. I understand that some devices may act-up when transmitting, but my two door openers are practically deaf now. I bought new batteries today and the door won't open unless the remote opener is a few feet from the receiver. The wire buttons of course open/close the door perfectly.
Last night when we returned home, the garage door bulbs were off, the garage was dark, and it still wouldn't open - I waived the remote around in the air with the button pressed and it eventually opened.
On a perhaps related note, my Vizio soundbar mysteriously died Friday night while watching a movie. It is dead. I opened it and didn't see any blown/bulging capacitors. Googling the problem, I see many others have similar problems with the Vizio soundbars crapping out after a few years. It is coincidental that the garage door openers and soundbar are both affected the same day.
I was not transmitting when the soundbar died - the radio was off and we were watching a movie.
As I lead-off, very strange.
Could the front-end of the garage door receiver be damaged? I presume it either works or doesn't work. It doesn't make sense that it works but only when the opener is a few feet from the receiver.
