The main problem with this, it automatically switches ON with no display then it switches OFF after 2seconds... And the led indicator at charging port acts like a strobe light. 3vdc and 5vdc from TPS51125 is normal while it is still powered ON when it switches OFF those supply voltages were also not measurable then suddenly it will appeared again and the unit will switches ON by it self. And it will only repeat the process of Switching ON and OFF. Tried already replacing the TPS 51125 but no changes....
Thanks...
