Hi
5800 only vibrate no on
1. By using a scale manually Multitester x1, connect the cables Multitester with positive and negative poles of the Vibra component, if the component is vibrating in a good situation, but if the components do not vibrate Vibra then you need to replace the defective component Vibra.
2. Further examination could be done if the component is not damaged and remained Vibra still using Multitester, connect the cable to the interface component Multiterster Vibra on phone PCB, if there is movement of the needle when it is connected Multitester the path under normal circumstances, otherwise if there is no needle movement means there is a path Multitester end. You can make jumpers system directly from the UI to the component controller IC Vibra. Check also that the positive path from the battery to the Vibra in good condition, if the track is lost then do the path-breaking jumper on you, then the vibration will work again.
