Good day all,

 

I really need your help as i faced a dying battery and while trying to start the car the infotiemnent system bolero was switching on and off with every trial then suddenly it stopped workig at all and even the lights on its buttons are off also 

 

Does anyone faced similar case or does anyone know the place of the fuse responsible for the system ? Or could it be tottaly damaged :(
