The JBL Charge 4 that Never Sleeps

The entire fix can be boiled down to taking off the speaker-side passive radiator and reseating the control panel flat flex ribbon.

The rest is me rambling people to sleep - as per the usual programming on this channel.

I had a broken ribbon cable and had to order a new cable from China. Surprisingly, it was fairly standard size ribbon cable, but I did have to measure the width and the amount of wires in the cable. These seem like a weak spot of the Charge 4. Also, some charge 4s have the front of the grills screwed on and the backs clipped, but others have all 4 parts clipped! They’re made in 4 separate factories, with 2 notable different case and driver designs. If your serial number starts with GT or GG there’s screws holding the front side of the grill. For serial numbers TT and TL, the grill is clipped on both the front and back.

как показывает практика, иногда достаточно просто разобрать/собрать и всё снова работает нормально)
