A1466 820-00165 Pulsing

[Instafixx]

Device came as in not turning on.
Corrosion at U7600 and 1pc Cap near SMC.

Replaced both. Now its Pulsing and sometimes turning on.
Replaced U1950 and U5110 as well. Still the same.
WOnt turn on in SMC bypass mode as well.

SMC issue?

Bypass F7140, to confirm its really good.
If works, replace it.

 

[Instafixx]

Bypassed. Still the same situation here.
It will turn on once. then after 2-3 mins of use it ll shut down and wont turn on. Leave it for 10-15 mins and it will turn on again.

During the not turning on period U1950 // SMC AVREF // SLP_S4_L etc are pulsing every 2 seconds.

Test reballing SMC.

 

[Instafixx]

Did that. Still the same. Should i change the SMC ?

If you have a known good one, is the better way to discard it.
