Hey guys,
working on 820 00045, No one touch on this board before me and don't have any corrosion! the customer said that he stopped working suddenly!
All "G3Hot" (Always-Present) Rails are present and stable until PP5V_S4.
From PP5V_S4 to PP1V05_S0 are pulsing!
For example PP5V_S4 are pulsing 5V and off - 5v and off! Like to PP1V05_S0 1.1V and off repeatedly!
Already replace U4700 for a new one and no changes!
Any idea to this one?? already searched on forum but i can't find any problem related to this!
thanks
