Headset has no power at all

Wasn't using headset for like a week and it was always on charging all the time. But when take them has no power at all. Tried diferent cables, nothing. Check battery with voltmeter, baterry has 3.6v. what could be wrong.

@oldturkey03 here is photos. With first look can't see anything wrong. I don't know where to start checking.

@oldturkey03 Sorry for bad quality photos. There is light indicator, not sure that can couse a problem. Here's i hope better quality photos.

@lukaskrapa67278 it is still possible that his is a bad battery. It may show the right voltage but once you apply a load it may fail. If unsure about the battery age or the battery health, I would start with replacing that.

Ofc course, it is possible that there are issues with the DC-in circuitry on the board or even the power circuitry but there are no schematics out for this, so you would need to check the components on those boards. You can attach pictures of it with your Question. That way we can see what you see and maybe someone can identify any issues with those,

@lukaskrapa67278 thank you for those pictures. Only trouble is that they are not well focused. Remember that there are no schematics so we will actually have to try and identify some of these components by looking at them. Post so pictures that are more focused.

It appears as if there is a fuse right next to the red cable. Use a multimeter and check that component for continuity.
