Well I got around to messurea bit today and I have 5.2 V on the fuse and on pin 5 but 0 on pin 6. I also have some shorts on the caps under the cpu. Id say thats that and move on but then the thing still boots and works. It just wont charge... so it cant be a total failure.
Checked the lines...
The coil only carries the battery voltage and the switch does not recognise the charger at all. I'd think it has to do with the port but I can connect the switch to the pc and push payloads and such.
As I have never heard of the coil going bad ('' it's never the coil") does that happen a lot...
Thank you for this. My values look a lot different for some of them. The big grey ones all show 0.0 and 3 show OL. So I need to find the cause for this. I think it might be p13usb. will try to source a good one. Last one I bought was just pulled off and had no pads left on him...
Thanks you so much for that word dokument. Its rly helped me. I have a switch that wont charge. Changed bq but still nothing. It does turn on if I put a battery with charge in it though. Now I have found that the caps around the 3 phase buck regulator under the emmc are all short and one even...
Hi,
I bought 2 non working switch docks and apon closer inspection they differ a lot. One is missing a lot of components the other one has and has components in places the other doesnt. Are there different versions of the dock?
Well you prly have a short somewhere else on the line. As I do not know what cap you are talking about and as we do not have schematics iam sorry but I can't help you. Maybe tell us which caps are shorted?
