Hi,

First verify whether or not the speaker is still covered by the manufacturer's warranty period.

If it is, consult the documentation that came with the speaker or go to the manufacturer's website to find out what you have to do to make a claim for a warranty repair or replacement.

If the warranty period is no longer valid, here’s a video that shows how to replace the battery that may be of some help

My speaker doesn't want to open and does not charge

I was having the same problem with my two megaboom speakers. I tried almost everything but to no avail. Then I tried using the original yellow USB cords with the yellow outlet plugs and IT WORKED! Was able to charge them fully! Hope this helps!

I have the same problem with my UE MEGABOOM. I have the original charger with it but it’s not charging at all and cannot come on without it been plug to current. What can I actually do about it?

Trying to fix my father-in-law’s speaker and stumbled across this site. The battery says critical battery please charge. Ive performed a series of resets and volume button holds to no avail. theres a small flashing white light that lasts for about 10-12 seconds before powering off again. Tried a number of different micro-usb as well. Any advice would be appreciated.

Hi @mattsomoto

There may be no other option than to open the speaker and check that the battery is OK.

My Megaboom would only work while plugged in. When turned off charge light would not work. Not charging. Tried rebooting, used different charging cables and outlet plug. Still nothing. While plugged in with yellow cable and plug pushed the volume up and volume down together to check battery life and speaker said 40%. Looked at the bottom and charge light was flashing. Go figure……. working again for now.

My UE MEGABOOM only was playing while charging. When I displuged, it stopped playing (but da light of the on/off button was still on and my phone was still reconizing it on the bluetooh).

I did the following steps said by Andrew Pifferini  on the link below:

Why won't my speaker turn on?

Now is playing without the charging cables.

Hope this helps;
