It’s fine, you’ve essentially replaced it with an infinite resistor. With the low currents that a microphone generate, theres just no signal going into the ADC now so it’s just silent.
So if the remote still works then wouldn’t that mean there is still a microphone? Or have they gone back to line of sight infrared? Or am I just thinking of the really really old remote tech?
Not fully related, but early TV remotes used sound rather than IR. The buttons made a distinctive “click” noise, from a mechanical mechanism. The different clicks were detected in the TV and used as input.
Plus side, no batteries to deal with.
Down side, about as (un)reliable as you would expect.
Cool, thanks! No problem. I understand it was analog electronics and using an ultrasonic signal makes sense, but what I wondered about was how did the receiving end (the TV) differentiate between the signals for the different buttons and then decide to execute different procedures based on that. Still pretty interesting in any case.
While it’s not always the case, try to look for a 2x4 silver rectangle with a hole in it like the one on my finger. The casing is to isolate it from the nearby radio waves and the hole to let sound through.
This should be a web site or YT channel. How to remove such bits without bricking the item.
To be fair, OP didn’t claim that the remote wasn’t bricked…
It works! I was fully prepared for it to not work and explain to my wife why we need to order a new one, but no issue at all lmao
Could probably have measured its resistance, then put a plain resistor in its place.
Probably, but the nuclear option is always more fun
With these people (advertisers), the nuclear option is sometimes the only real option.

The microphone would only be used for voice control. So that would fail, but buttons would still work normally.
…when have remote signals ever used microphones?

That’s wild. How did the TVs identify the distinctive sound? That seems like it would be a pretty interesting engineering trick.
I believe it was old school analogue electronics, but I’m speculating there.
I just looked it up, it was ultrasonic signals. The main one was the Zenith Space Command.

It’s a smart remote, they use bluetooth or IR as a fallback. The microphone is only for voice control.
Looking up which part to nuke took an hour, but anything to calm down my paranoid ass haha
“Oh good, he fell for the decoy”
oh no
Could you share your knowledge here? I clicked this thread expecting to find instructions to help us follow your advice.
