Member: 1176031 Status: Offline Thanks Meter: 62 | Hi Wites, I think I've got an easy question for you, but I'm confused what to remove first... So I've got this 3GS board which is getting really really hot when charging and also draining the battery while charging. So I opened it up and checked L9_AP charge coil and it was beeping then I checked the charge coil against the GND and it was shorting. I checked also the D1 diode (next to this charge coil) and it was also shorting. The question is which one do you think is bad, diode or charge coil? |

I made a simple drawing to get a clear picture of what's the problem. Also I tried to unsolder both diode and coil but I can't is it hard to do so? Seems hard to reach solder melting point ![]() | |
