    Hi everyone, description of the problem, maybe you can help :)
    I bought these speakers over two years ago:
    https://www.morele.net/logitech-z533-980-001054-802784/
    A month ago the warranty ended, today the potentiometer broke by itself (coincidence? -,-)
    At minimum volume, it turns on, I can hear it working, etc. Unfortunately, when I change the volume, it turns off.
    In the attachments I recorded a video of what exactly is going on, and in the picture what it looks like from the outside.
    I will definitely not buy new speakers because of such a thing, I can see the dedication to the service on average, what do you advise?

    After all, there is no service without the service.
    Or take it to some electronics, someone eventually has to replace this potentiometer.

    "Working" in what sense?
    The sound from the speakers is?

    I can't see the photo of the potentiometer, but if it's fairly typical, it can be replaced.

    I will connect because the topic is not old and I am currently touched ;) Logitech Z533 set, when turning on the potentiometer, the power indicator blinks and goes out, the speakers are dead. I messed up the pilot:

    in this black stand under the potentiometer there is a switch and it died. I soldered a rude jumper:

    And it works ;) Of course, the set is powered all the time, which I don't like, but tomorrow I will add a switch on the power supply and it will be ok. Maybe someone has an idea where to find such a potentiometer and is it worth looking at all?

    I also had a problem with the potentiometer. Does anyone know where one can be purchased or is it possible to buy a remote control somewhere?

    Two days ago I had the same problem. @thomasc Could you explain how to open this potentiometer at all? I don't want to pull anything by force, and I don't see any screws. Alternatively, can you buy the potentiometer and replace it yourself?

    To unscrew the potentiometer itself, you need to find three screws under the rubber base. The knob itself needs to be pulled upwards. The potentiometer is soldered into the board in as many as 10 places. So maybe it's worth doing as the patch wrote on the forum to bridge the power supply permanently and add an additional switch itself. How can you ask

    Hey, thanks for your help, I did exactly as you did and it also works, tell me where you added this switch? is it going to be done with a potentiometer? If so, please advise, thank you in advance :)

    After making the "rude jumper", as in the posts above, I connected the speakers to the "rude" electrical divider with a switch. Simple and effective. It's just a matter of habit.

    It works thanks a lot. Mine had crackles first, then nothing. After soldering the jumper, it works - tomorrow I'm buying a switch.

    Hello, has anyone managed to find a potentiometer for speakers? Unfortunately, I also had this problem and I would prefer not to do them "shortly", I searched the entire Internet and did not find such a potentiometer anywhere :-(

    The only option is to look for Alliexpres or regenerate the old one. Except that the latter can be difficult or impossible - it depends on the damage and "agile hands".
