I have a problem with an 820-3437 the pp5v_s4rs3 signal varies between 5v and 0v, it is not stable in the same integrated system, it generates pp3v3_s5_reg_r of 3v3 that if they are stable with what the computer does not start the fan is seen to rotate a little and it stops. Green light that turns to orange making measurements I see that q8150 does not have 4 ALL SYS PWRGD in its output due to the instability of PP5V S0 while medium voltages I saw that the measurement of leg 5 saw how the tension was fructifying and in a method it is set to 0.67 V and the fan begins to rotate faster and faster and by measuring I see that the 5V voltage of pp5v_s4rs3 has stabilized and I have tension in the memory and cpu coils I do not know why this occurs
I hope your help thanks.
