Hi Folks
My Anker 6 port USB charger stopped working. There was no signs of life. so i opened up (they make it real difficult to open) .Anyways on opening and looking around for long the following are the conclusions
1. The AC plug socket on the motherboard was knocked of the board.. But this could be a result of my using brute force to open the adapter. But the fact that the socket came clean off the board would indicate a possible cold solder joint.
2. The fuse next to the AC adapter was blown.
3. Knowing the fuse was only a symptom and not the cause. I looked further and found a damaged diode(Diode D1). The diode was in line with the 0,33uf X2 capacitor.
No my problem is i cant identify the damaged diode. There is another diode next to it and is marked as A7. I am assuming that the damaged diode is also an A7. Problem is i cant seem to find this A7 diode in any store here. So i need the following help
1. Does anyone know alternatives for the A7 Diode. I cant find it in any of the stores here. The data sheet for the A7 Diode is here.
2. Do you see any other issue with the board
There is a possibility that the diode D1 was also damaged when i tried to open the charger. I guess this because the diode is showing physical damage and not burn damage. So i am going to replace the fuse and the diode and then see what happens.
So please advise if anyone knows the alternative for the A7 diode. Also if you can see any obvious issues with the board
