Just an update on this one. This ended up being a bad APU. I re- balled and reseated the APU but it was too far gone.... -
Please keep me posted. I don't have a BGA Rework station to reball and reseat the APU so I didn't go that far. But our issues we are having seem to be the same. I would be curious where you land this one. Good luck!

PS5 Where to find MAC addresses in BIN
Does anyone know what line in a PS5 Bios BIN file to reference for the WIFI MAC Address and Ethernet MAC Address? I know BwE's Ps5 Nor tool will do a harvest of MAC's but there has to be a manual way to find them in the file.Last edited by TheWizard; 04-02-2024, 04:02 PM. -
Update on this one. Connected UART and I am showing an error of 80000140: APU Freeze (No Response) - GDDR6 Data Line Issue (Replace). Thermal camera showed RAM module 6 not lighting up. Reballed the module and reseated. No change. I then replaced the module with a known good. Still received no change. What makes up this data line besides the APU and the RAM?

Groomit,
Were you able to resolve this? I had the same symptoms and upon using thermal camera. RAM module 6 was not lighting up. I reballed but no change. Replaced with NEW known good module but no change. UART shows the same error code "80000140: APU Freeze (No Response) - GDDR6 Data Line Issue (Replace)
Just wanted to see if you got any futher? Thank you.Leave a comment:

Does anyone know what this chip is and possibly have a datasheet for it?...

Flir thermal cam was misleading me a bit by making me think there was a cap or nearby inductor heating up first. Not liking how the Flir shifts the thermal layout. Went old school on this ps5 last night and broke out a can of freeze spray. First component to get hot was the NXP chip followed by inductor and nearby cap. Looks like I will need another wifi module. Trying to source the AW-XM501 this time.Leave a comment:

Anyone have any further ideas? One thing I have noticed is my know good EDM-020 disc edition board has an AW-XM501 wifi module. Not the regular J20H100 module. Not sure if that is related. I heard both were compatible....Leave a comment:

Took some new thermal images. Providing 12v @1a. I am drawing 51ma. During this stage the Wifi IC heats up along with the (Dialog) power regulator and One Flash memory chip for Nand. After this sequence the amps drop to 21ma and components cool down. See pics...

Update: I re-balled the 2nd replacement wifi module and soldered back to board. But this time I left the shield off the module so I could take readings from components directly on the wifi module. I have my 3.3 on the test point located on the motherboard. I also have 3.3 and 1.8 on the caps for the wifi module itself. The only time the f7002 circuit reads a short is when the wifi module is soldered to the board. If its removed the diode readings for the f7002 circuit go back to normal. The short also exists on the caps on opposite side of wifi module. But those shorts go away as well when the...Leave a comment:

Thank you for the advice jasko_jacker. I will try this after i finish up with the PS5 i have been battling. Much appreciated. Stay tuned.Leave a comment:

Just an update on this one. I requested a full refund and got it. Haven't bought a battery yet. I may just use it as my new lab machine. Laptop is fast. And i will never use it's portability anyway. Or should i keep digging at it? Jury's verdict? HahaLeave a comment:

Lotas,
So the only cap showing a resistance to ground reading is the one at the left in the picture you modified with circles. That reading is 3.250 mohms. The others all show OL. The cap with arrow in this new first pic was showing short. So i removed. Short was still there. Traced it back to the filter. Removed that and short was gone. Not sure if related because i dont have a pin out for this chip. Next step would be to replace filter and see if short still exists. May be reliant on chip to be there....Last edited by TheWizard; 01-20-2024, 09:55 AM.Leave a comment:

Lotas,
Which caps are you referring to? The two big caps at the bottom middle of board have readings. As you get up to the right of the chip seems like that is where shorts start.Leave a comment:

Sorry just saw your inquiry for what programmer i was using. I use the TL866 II for my chip programming. Hope this helps. Sorry for late reply. Have a great weekend! -
Okay people I am back at this one again. Anyone know the best way to test the wifi module for the PS5? Anyone have a recording of known good diode readings etc? I was just using the ground point at the bottom left and probing around the board from there. I have three of these modules and all three produce the same results on the board. Any ideas?...

Jasko_jacker,
i have updated the bios by downloading from Asus's site. But have not pulled the chip and set it in a programmer as of yet. Issue happened prior to bios flash as well. I can pull the chip. Backup BIN. Erase and reprogram. If you think it will advance us.Last edited by TheWizard; 01-10-2024, 03:51 PM.Leave a comment:

Assembled without mosfet. Laptop has the same symptoms as before. Battery will boot up and run laptop when AC Adapter is not connected. Laptop recognizes when AC is connected. Windows starts to indicate charge then drops after like 10-20 secs....

One thing i wanted to point out though.
mon2,
Where we removed PQ8803. I took a reading and the gate pad of where that mosfet would sit is reading 1.73. Shouldn't that be like a 0.45 or so voltage drop instead?Last edited by TheWizard; 01-10-2024, 10:53 AM.Leave a comment:
