I got my hands on a Philips Hue Go lamp that was not working properly.
Model# 71460
The symptom was slow flashing purple LED (error code?) but it would not stay lit nor are you able to connect to it via BT or Zigbee.
It did not come with a charger but when I probed the power pads (12V) I was getting a slight spark so I knew there was a short somewhere.
I was able to find a hotspot on an IC but I am having trouble figuring out what it is as there is absolutely no mention of the markings anywhere on the web.
Attached are some photos of the PCB and the IC in question.
The IC has the marking "BGW7NB". I have circled the spot where the short seems to be located (based on where it gets the hottest).
Now i am not actually sure if this hot spot is a short. It was just the hottest part on the board. I have no idea if it is supposed to run hot bcos I am not sure what it is. It maybe a proprietary power IC that has other functions integrated in it which makes it run warm even the light is off.
Any help, tips or ideas would be greatly appreciated.
