JBL Charge 3 Speaker: Unexpected Shutdown Post-Pool Exposure - Bluetooth Connection Issues

DziadGrzybal 18855 10
Best answers

Why does my JBL Charge 3 turn itself off after a while when connected by Bluetooth, especially after being taken out of the pool, and what should I check or do?

The most likely cause is water damage: a short circuit at the input or on the motherboard, or a battery that was damaged and lost capacity after the pool exposure [#18019453][#18028757] Drying it alone may not be enough; open it up, inspect the board for burn marks or green corrosion, and clean it with isopropyl alcohol or another PCB cleaner, then dry it again [#18028757] Check the battery voltage with a multimeter and look at the battery indicator, since a failing battery can also make the speaker shut down [#18019433][#18019503] If possible, try charging the battery with a 5V supply or externally and see whether the speaker starts and stays on [#18019503][#18030220] If it still shuts off after cleaning and voltage checks, the board or battery may need replacement [#18030220]

    Hello, I have a problem with my jbl charge 3 speaker.
    Namely, the point is that I turn on the speaker, connect to it using bt and play music. After a while, the speaker turns itself off.
    Anyone have an idea what to do?

    Added after 5 [minutes]:

    I will add that it happened after taking it out of the pool (there have never been any problems with its waterproofness)

    Hello, how about the battery indicator? Is it charged or has one dot

    well, I'm betting on a short circuit at the entrance (you can spray alcohol and blow it out, for example with a pear) or the battery just got a short circuit and lost enough capacity
    off topic, I will say that it is not the first flip I make that is supposedly waterproof. But you don't necessarily have to break the middle through the water

    On Monday I'll take him to work and my friend and I will try to work something out
    If anyone else has any guesses, please let me know.

    Good idea, it's not very complicated, but it's quite hard to get inside, check out this entrance and to exclude batteries, if you have a meter, measure it (how many volts) and, apart from the speaker, try to charge it with a 5V power supply if it charges anything at all

    The motherboard was flooded, we dried it and nothing (there was still water)

    Well, sometimes this water resistance, as I said, is not 100%.
    Is there any burn marks or greenish coating on the contacts (tarnish) on the board? Drying alone is not necessarily enough, it is best to wash with a PCB preparation, possibly with alcohol, e.g. isopropanol.

    Any chance to save him? I'll let you know tomorrow if there was a raid
    We just dried it thoroughly and it didn't work so I figured I'd wait

    there is always a chance that after cleaning with alcohol and visual inspection, if it still does not work, you need a multimeter in hand and measure. After connecting the USB, what voltage is present on the battery contacts (if it indicates anything at all).
    post a picture of what the situation looks like

    Here you have a similar topic https://www.elektroda.pl/rtvforum/topic3505732.html
    try charging the battery on an external power supply and plug it in, see if it starts at all

    greetings
