Coby CSBT 322 bluetooth speaker wont respond. Light will come on when charging but won't work when power on

Depends what it is.

Try doing default factory settings.
Step 1. Press the "Power" button located on the top center part of your JBL Charge 4 Bluetooth speaker. The speaker will be powered on when the LED backlight under the Power button is lit.
Step 2. Hold down the "Bluetooth" and "Volume Up" buttons at the same time for roughly three seconds. The Volume Up button looks like a plus sign. Additionally, it's important to hold down the "Bluetooth" button in the center of the device next to the Power button, as it's easier to hold down. After three seconds, the LED ring around the Power and Bluetooth buttons will briefly light up before the JBL Charge 4 powers down.
Step 3. Press the "Power" button again to turn the JBL Charge 4 Bluetooth speaker back on. The Charge 4 will instantly turn on in Discovery mode, with the Bluetooth LED blinking on and off, and the speaker making a pinging sound. This confirms that you've successfully reset your JBL Charge 4 to its default factory settings. You'll need to pair or re-pair any devices you want to play audio through the JBL Charge 4 speakers with the device.

1.Check the LED light
Generally speaking, the LED light will start blinking when you connect the charging cord and charger to your Bluetooth speaker. Like the EasyAcc Mini 2 Portable Bluetooth Speaker features a 360 degree LED light which wraps around under the top metal and indicates the charging status. If the light is broken, probably the speaker is charged for real but the light says the opposite. If this is the case, try to turn it on after 1 hour's charging, if it works fine the LED light is broken for sure. It's not completely handy to use the defected Bluetooth speaker but at least there's no other system problems encountered.


2.Switch the charging cable and adapter
It has a great chance of applying broken cable or charger when the Bluetooth speaker not charging, therefore go to switch them to identify whether they are at fault or not. If so, directly replace them to qualified ones.



3.Clean charging port
Chances are that the charging port is choked with lint, dust and dirt. A can of compressed air can blow out the offending irritants and get your USB connection back to normal. If the charging port becomes loose, do not try to fix it by yourself if you don't get any experience with the tools like pliers or tweezers. Go to ask customer service or someone with solid skills for help.


4.Update/Reset software
The dead battery issue also occurs when the software is out of date, the manufacturers regularly release the updates or upgraded drivers to solve the corresponding problems. This happens on lots of rechargeable devices out there and there is usually a fix.
After all, if still says not charging, contact the after sale customer service and get support immediately or get it replaced under warrenty.

Hi,i found that some bluetooth items like speakers will only "lock" on to one bluetooth device. If you have other bluetooth devices in the area you have to disable the other paired devices that it is reading.
Some more expensive items will let you pair as many devices as you want but this may not be the case with yours,"unpair" other items. This may work

i keep charging it but the light will not come on and when i press power it still wont come on

replace the cable

If its two weeks old why are you here? Take it back to point of purchase and either have it fixed or replaced or get a refund.....

From the brand you likely are in UK but here all sets come with some kind of warranty==the problem sounds like a power supply issue but if you have a warranty and open the set it will void that warranty.

Mine does that to but all I ever do it just hit the reset button on the back and it turns back on.

SImply connect the headphones to a power source. Then press up and down volume buttons at the same time. It will reset the headphones.

I have a COBY DVD player TF-DVD7005 that hadn't been used in a while. When I charged the battery and the light went from red to green, nothing happens when I push play and the DVD doesn't spin. Could the battery be dead despite the green light and where would I get a new one?
