PS3 FAT NEC/TOKIN Resistance Testing, need help interpreting values

[jkucukov]

I'm in process of diagnosing the yellow light of death symptom on my PS3 FAT console CECHG01, in process of getting the Arduino gadget to be able to access Syscon and be able to read fault codes. In the meantime, I'm trying to measure resistance of the NEC/Tokins while still attached to the board. I took the Ohm readings from each of the NEC/Tokins from front and back of the board (4 from the RSX and 4 from the CPU chips).

What I gathered in the attached pictures are values from the CPU NEC/Tokins are consistently measuring 1.6 Ohms while on the RSX they measure 3.4 Ohms except for two places where its open circuit (OL) no measurements. I understand that these are like capacitors and are hard to measure on the board. I hope somebody more experienced can tell me if what I'm seeing is a set of bad NEC/Tokins on the front side of the board or a bad RSX chip?

Thank you for sharing, the values I was able to pull from looking at the shared diagram is as follows:
RSX_VDDIO = 85.2 Ohms
RSX_PLL = 5.78 kOhms
RSX_VDDC = 4.1 Ohms

Keeping my fingers crossed 😊

values will be different for a "G" board because they use 65nm chips instead of 90nm
