Nevertheless, there is no reason to reboot; instead, we recommend you power cycle your speakers since this will completely reset their state and enable them to return to normal. Thus, you should try this and see if it helps.

Fix 2: Reset It

Resetting this speaker to factory settings will erase all data and restore it to factory defaults. If you cannot connect to the device over Bluetooth or if it won’t turn on, this is an excellent troubleshooting step. If you perform these steps while the speaker is plugged into its charger, make sure it is unplugged. However, once you unplug it, make sure to perform these steps to factory reset your speakers:

1. Unplug the speaker from the charger. This will prevent it from charging while it’s unplugged.
2. Then, plug the speaker in after pressing the power button to turn it on. So, press the power button while holding volume + and playing. This will allow the speaker to restart after three seconds.

Fix 3: Defective Batteries

A defective battery may be the cause of the problem. However, the problem would be fixed if the battery were replaced. Meanwhile, among the reasons why batteries fail are when they are constantly overcharged or when they are regularly exposed to heat.

Both of these factors contribute to a rapid decrease in battery performance. Therefore, it is recommended that you check out your batteries or visit your nearest service center if you have any technical knowledge.

Fix 4: Charge the JBL Partybox Speaker

So, you must plug the AC power cord into a wall outlet because it is all that’s required and also connects the other end to the speaker’s back.

After that, let JBL Partybox charge until the battery charging indicator indicates that it’s full. Finally, turn on the JBL speaker after the charging process is complete to check if the won’t turn issue gets resolved or not.

Fix 5: Check For Damaged
