Question [Q] Charging animation not available

1. My n7000 battery charging animation was not available during charging, what is wrong, could somebody point out pls?

Step taken to solve but didnt restored the animation:
- Reflash new rom via odin= no
- Reflash with pit via odin=no
- Reflash custom rom=no
- Reflash s4 system ui=no
- Replace micro usb board=no
- Replace battery=no

The phone can charge the battery but with no animation, even in lock screen there was no indication of charging.
What could be the missing?
