Fix: If JBL Boombox 2 / 3 Not Turning On
It won’t be very tough to fix the JBL Boombox 2/3 not turning on issue; so, in case you are facing this problem, check out these fixes:
Fix 1: Check the Battery
You need to check the battery first when troubleshooting your JBL Boombox 2 or 3 if it isn’t turning on. Here is a detailed explanation of how to check your battery:
- Make sure the speaker is fully charged. When the battery level is low, it might not be able to turn on. If you want to charge the speaker, connect the power cord to a working outlet.
- On the speaker, look for a battery indicator. There is a battery gauge on some JBL Boombox models that displays the current battery level. Depending on the battery level indicator, the device may need some time to charge before it can work.
- Batteries must be checked regularly to ensure they are in proper condition. If the speaker has been used for an extended period of time, its battery might have been depleted. When you turn on the speaker, disconnect the power cord and check the battery life. Whenever the device turns off after a short period, it means the battery is depleted and needs to be recharged.
- You should check the connections to the battery. Even if the battery is fully charged, the speaker will not turn on. Check the battery connections if the speaker still won’t turn on. You should check the battery connections and battery compartment for visible damage, and ensure that the battery is clean and secure.
If your JBL Boombox won’t turn on, take these steps to find out if your battery is the problem. Ensure that the battery is fully charged and that the speaker connections are secure before proceeding.
