Hey there! After some troubleshooting I have found that U14, which is marks as BC0A, but actually TPS22965DSGR_SON8_2X2, is getting hot and blinking from hot to cold. Some protection scenario
The problem is simple. After passing switch, there is a short somewhere. It could be a charging controller, it could be a lot of different ICs which requires +5vs or one faulty component.
Recently I watched a lot of repair by northbridgefix at YouTube, and most of repairs were made without voltage injection. I am afraid to inject voltage as my 0.8 v power supply is broken and I do have a 1.3v only for injection. I remember that the best option is 0.9-1.0v for injections.
Maybe there is the other way to fix without burning components?
U14 looks clean and Normal, so I think that problem is not there, also ic shutting down after few second and looping that again... on of..
Thanks for advices!
