Why can't I turn my phone on? Battery is checked OK.
My phone suddenly went down. I thought battery was low, so put him to charge without success.
It won't turn on nor charge (always black screen, no light). My external batterie detects the phone when connected, but the phone stays off and not charging.
The battery seems pretty charged (3.3V on 3.8V)
I tried VolUp+Home+Power, VolDown+Home+Power, VolUp+VolDown+Home+Power, but nothing happens...
Is the motherboard dead ? repearable ?
Cette question est-elle utile ?
After more tries :
- Battery is OK
- Charger is OK
- should not be the power button because it does not react to charger (no charging screen)
- should not be the screen because no vibration when pluging charger or try to power it on
- The phone don't react when i try to power it ok whith a fully charge battery
