Jerry, take your phone camera and shoot the wording on the screen when you turn the fan off.

I wish the text had stayed on the screen long enough for me to read it. All I could see was "HDMI." I think it did this three times, but three days in a row - although not last night.
I'm not sadistic enough to torture my electrics with all that on and off.

Make a video of the screen so you can slow it down in a video editor.

Most UPS systems run on line power while keeping the battery in standby mode. Upon power interruption the inverter very quickly picks up the load (within a portion of one cycle).
I believe the HSMI connection is usually to a computer to trigger an orderly shut down. Since there is no computer to shut down in this case perhaps the UPS is looking for a connection.

How old is your house and the wiring in it? Have you had work done on any of the electrical circuits by people that weren't qualified electricians? The reason I ask is because my sister had a lot of work done in her house by a handyman that cut into a lot of lighting circuits and has caused some electrical gremlins. One circuit above her dining table for a light had about 5 different (white) neutral wires and when I touched one of them I got shocked. That led me to think he used that lighting circuit for something else and now the neutral is NOT balanced. Circuits that are not balanced can cause all kinds of weird things to happen.

Set up a camera to take a long exposure of the TV screen, open the shutter a fraction of a second after shutting off the fan. The long exposure may then capture the writing on the TV screen and therein may be your resolution to the problem. And there are magnets involved in an AC current motor, there are electro magnets that change polarity with the alternating current flowing trough them.

Not sure what you mean by "balanced" neutral. Usually the neutral is grounded.

I don't have any idea about your TV problem Jerry, but I can say that since I've been a member here you have both bought more new pieces of technology and more of it has broken that anyone I've ever heard of. Good for you for keeping your sense of humor. I would have driven out and burned down Silicon valley by now with all the crap you've had to deal with.

This strange behavior began a few days ago, but it didn't happen last night, so unplugging the fan would have uncertain results.
Plug into a different receptacle.

Everyone does. "Well, it's running fine now."

"Phone camera"? Surely you jest.
I have my D750 right buy my chair, set to shoot continuously. Unfortunately, as soon as the TV saw the camera, it stopped misbehaving.Sep 14, 2021 20:52:32 #

(Also seen in humans, but called the "doctor effect" - you walk into the doc's feeling lousy, and by the time you get to the receptionist, all symptoms have disappeared!) 😱

Exactly. It hasn't acted weird since I posted about it here.
