Version 1.3 of Tronsmart Onyx Neo Bluetooth headset is corrupted. After one, two or three charging the case stops working.
There is a chip inside headset case which is broken. You can replace this chip but it’s not an easy task. In order to do it you need some experience and special tool – air hotgun.
BUT there is much easier way. Although it won’t be a „full” repair but it enables you to charge you headset. Still – you will need soldering iron tool.
You make all repairs on your own responsibility!
Steps:
- Dissemble case – simply put some tool (i.e. old credit card) and pry, it will pop out.
- Unscrew the two screws.
- Desolder two wires from the battery. GND & VBAT (pict.: 1 & 2, no 1 on 2 pict.) (sorry but in this repair variant in-case battery won’t work).
- Secure endings of battery or simply remove battery from case (it is glued).
- Don’t remove the whole chip – black color chip in middle of electronic board (pict.: 2, right). On attached photo it is in the white-shining color.
- Only desolder chip’s „legs”/ ending / soldering points (pict.: 2). If you try to desolder, they will probably fall off – they are not needed.
- Prepare a very short cable (red color on pict. 2). Before proper solder apply some tin to its both ends.
- Solder upper end of cable to third soldering spot (upper part), counting from left: {1}{2}{3}{4}.
- Solder lower end of cable to first soldering spot (lower part), counting from left: {1}{2}{3}{4}.
- Done! Headset placed in case will start charging – red LED on headset. Although LED in case won’t light on.
Auto turning on/off option isn’t working as it should so to be sure just hold both phones multi buttons for approx. 4-5 second and you will hear: ON / OFF message.
