Turntable won't power on anymore

Hello everyone... and happy new year as well!!

I'm reaching out because I'm having a problem I don't understand, my AT-LP60XBT turntable won't turn on anymore. Previously, there was a LED under the Bluetooth symbol that indicated whether it was in pairing mode or not, and for me, it's information that tells me whether or not it's powered on.

By default, I leave its charger plugged in (to a power strip), but the charger itself is not connected to the turntable when I'm not using it because there is no on/off button. There is only a kind of standby mode, but I generally prefer to unplug it.

So this morning I plugged it in, but the LED doesn't light up, and even if I press "play," nothing happens. So I went to get my multimeter and wanted to see if the charger/cable was dead.

As for the charger, it works; I have 12V.

Then I measured the resistance of the turntable just in case a component might have burned out.

I hope I went about it the right way (I'm an amateur in electronics; I just watched a YouTube video for the connection).

From what I've read, if I don't get a "1" but any other value, it means the resistance works. So now I honestly don't know what to do...

If anyone has a solution, I thank you in advance and wish you a good evening.

    Hello,

    It is still possible for your charger to show 12v when not connected... Nothing indicates whether it collapses as soon as you plug it in and demand a little power from it...?

    What is its current in Amperes or milliAmperes, is it okay for your equipment?

    A good test consists of connecting a car light bulb (filament) of 10 to 20 Watts in parallel with your probes measuring the 12 Volts (1st photo).

    This way, the bulb will light up and the 12v will remain displayed on the tester... this is proof that it outputs a little power...

    If the lamp does not light up and the 12v drops close to zero, then it has no power and is defective... You should also be wary of the 12v cable and the round plug... which may also be faulty... Several strands broken inside, for example.

    Hello tvviste,

    Photo 2: what are you measuring? Nothing. You don't measure like that, except with an ohmmeter to detect a short circuit, and even then!!!!

    Photo 3 (0.98): - from 1 volt (you are in voltmeter mode), direct current and not alternating current.

    Photo 4 (14.2): 14.2 what? It's on Off!

    I have the clear impression that you are doing nonsense!
    Start by learning how to use a multimeter.

    If you know how to measure a fuse, start with that already! (on the board, but you need to open it and know what type of fuse it is (fast-acting or time-delay) and also recognize their shapes.

    Happy New Year 2024 anyway!
