Hello, I received a PS5 that had some previous work done on it. F7001 was blown and I replaced it after finding a short near the 2v regulator and replacing the offending cap.
I’m still not getting any power, and checking standby voltages I am missing 3.3v from the mosfet as well as the SBV chip above F7002 regulator. I can’t seem to find any shorts. The enable pin of the SBV chip are 0v.
I am getting 1.9V, 2.0v, 5v as well as 1.8v.
I’m not sure where to go from here, any suggestions?
I would check the southbridge pmic DA9065/RT5126. This chip generates the enable line for power group 1 (3.3V_SS_PG1) at pin 25 and 26.
Thanks for the guidance.
I get no 3.3v rails on any pins on this chip. I also don’t get the 1.15 on pin 8, though I get all other voltages.
If 1.95V at pin 29 EN1 and 5V inputs are present and there is no 3.3V or 1.15V output, I would change the sb pmic DA9065/RT5126.
I’ve replaced the DA9065, but strangely enough, I only get 3.3v out of pin 17. On Pin 18 I only get 0.3v
