Note: this is not a request for troubleshooting help.
For the past few years my 10ish year old “smart” TV will maybe once a week or so completely lose the ability to play sound in the Youtube app, and only in the Youtube app. Sound works just fine everywhere else. Bizarrely this is always triggered by an ad and never a video. Restarting the app doesn’t fix it, and neither does clearing the cache. Fortunately doing a full restart of the TV fixes it, it’s just irritating to have to restart because an ad somehow broke the sound.
What technological gremlins haunt you?
Not sure about this specific model, but in older cars things like this are almost always caused by either too high or too low resistance in the wiring harness or headlight assembly itself because that’s how the car detects when a light is out.
Hmm… so in theory I could diagnose that with an Ohm meter… if I knew the resistance it was looking for…
