PS5 Slim (EDM-044) - 2s BLOD - Error 80871060

[stetofix]

I hoped to see a thermal image from @BASHEER to see the difference to my image.
Since his shown coil is a 0.15 uH, I think the ciruit in question is the 1.0V_SOC_VSOC line.

 

[BASHEER]

That resistor (1 ohm) and capacitor (470p) seems to be a snubber circuit.
Those 2 should not get hot unless something is damaged.

In the picture you mention a 0.9v on the output of the coil.
The service manual for and EDM020 mentions a 0.85v output (0.85V_SOC_VMEMP) or 1.0v output (1.0V_SOC_VSOC) on such coils.
I can't determine from your picture which coil it is.
But it is either too low or too high.

Maybe the capacitor of the snubber circuit is blown and shorting the 1ohm resistor directly to ground, lowering the voltage.
The output from that 8 pin dual mosfet chip has some sort of feedback to the IC on the left.
Maybe some minor damage has an effect on the output voltage.

My redneck approach would be to replace that 470p capacitor first.
Probably anything in the same order will do.

Hi,


Latest Findings:


• Snubber Components (R0139/C0139): I removed the resistor (Yellow arrow) and the capacitor for out-of-circuit testing. The resistor reads correctly at 1 Ohm.


• Test without Components: I powered the board without these components, but the error 80810001 persists, and the voltage remains at 0.9V (slightly low).


• The Main Issue (Red Arrow): I found a dead short (0.000) on the SOC rail (Red arrow). On a healthy board, I expect a low impedance (around 0.060 in diode mode), but here it is a total short to ground.


• Component Swaps: I already replaced the Dual MOSFET (GA4N23), but the 0.000 short remains. I am planning to swap it one more time to rule out a faulty replacement or a bridge under the chip.


The Question:


Since the short (0.000) remains even with the snubber circuit removed and the MOSFET replaced, could this be an internal failure within the APU (SoC) itself? Or is there another common failure point (like a filter cap under the APU or another phase) that could cause a total short on the 1.0V_SOC_VSOC line?

"Regarding the thermal imaging, I will try my best to capture a thermal map of the entire board. However, please note that due to my current camera setup and the distance required to get a full view, the resolution might not be very high, but I hope it will be enough to spot any significant heat blooms on the SoC or surrounding caps."

I tested the same spot at my PS5 slim. Same 0.9V when powered and very low impedance aprox 0 Ohm if shut down.
I still think, this should be ok

Thanks for confirming the 0.9V and the low impedance on the Slim model; that’s a huge relief. Since this rail is healthy, I’ll re-install the components and the MOSFET.


Given the 80810001 error, what do you recommend I check next? Which other voltage rails (RAM, 1.8V, etc.) should I prioritize on this EDM-044 board?

What is your reading at the red marked spot?

Thank you always for answering me ,

"My readings at the red marked spot are as follows:"


• Multimeter FLUKE 101 : 0.182 (Diode Mode).


• Multimeter 2 (RF4): 0.246 (Diode Mode).

——-

noticed a discrepancy in the Diode Mode reading at this specific point (shown in the photo):


• My Reading: 0.340 (Diode Mode).


• Known Good (YouTube/Reference): 0.640 (Diode Mode).


I have already replaced the Southbridge IC multiple times and re-balled it perfectly, but I keep getting the same 0.340 reading every time. This suggests the issue might not be the IC itself, but something else on this line.


Can anyone confirm if 0.340 is acceptable for the Slim model? Or could this lower reading be the reason for the power sequence failure?


Thanks in advance!

On my working PS5 my reading is also 0.340 V.

circuit (1 Ohm resistor and 470pF capacitor).


I also noticed another issue shown by the yellow arrow in the image. At those two capacitors, the thermal camera indicated a short. Before removing them, the Diode Mode reading was 0.055. After removal, the reading jumped to 0.243, which confirms that the capacitor I removed is faulty.
The capacitance value good or bad

The heat at your thermal image video in this spot seems to be ok. I have the same heat spot while the PS5 is running.

The both caps at your second image should be the pin 3; 27-30 output at the SSD pmic. My readings at a PS5 slim in this spot are 60 Ohm and 90 mV. (It differ a bit to the readings table from a PS5 in post #2)

stetofix, I really want to thank you for your continuous support and the invaluable information you’ve provided. This thread will definitely be a great reference for anyone troubleshooting these voltages and values on the PS5 Slim in the future."
"I have updated my readings after fixing the caps at the yellow arrow spot:"
• Diode Mode: 0.225
• Resistance Mode: 85 Ohms
• Voltage (Power On): It pulls exactly 0.800V (800mV) at the yellow arrow spot.

I have ordered a working PS5 Slim board so I can measure every single rail and component. My goal is to create a complete reference map for the Slim model and compare it with my faulty board. I will share all these findings and measurements with you and the community here, as I believe it will be a very helpful resource for everyone."

Hi stetofix,
@stetofix

I have some breakthrough updates regarding the PS5 Slim (EDM-044) that might be very useful for the community.


1. The Breakthrough: Error 80810001 is Southbridge-Related


I have confirmed that Error 80810001 can be caused by a faulty Southbridge (SB).


• The Discovery: Even if the Southbridge IC shows normal impedance and appears to work, it can fail under load. One of the voltage lines linked to the SB was dropping during the boot sequence, triggering the error.


• The Result: After replacing the Southbridge, the 80810001 error vanished completely.


2. Progression and New Error 80830061


After the SB replacement, the console finally reached the "Repairing console storage" screen. It reached 100%, but then failed to restart properly, throwing a new error: 80830061. This points to a definitive failure in the SSD data path.


3. SSD Controller & DDR4 Diagnostics


My diagnostics also pointed to a "DDR4 shorted or power failure." To investigate:


• I performed a rebuild/reball of the SSD Controller.


• I performed a rebuild/reball of the DDR4 IC.


Current Status: Despite the reballing, the error 80830061 persists. This confirms that the issue is not just a cold solder joint but likely a physical internal failure within the SSD Controller or the DDR4 IC silicon.


Conclusion & Next Steps


I am now certain that Error 80871060 is a dead SSD Controller, while 80810001 is often the Southbridge failing under pressure. I will now proceed with a full replacement of the DDR4 and SSD Controller and will update you all on the results.


Thank you for the support; we are very close to fully mapping these Slim errors!


To isolate the 'DDR4 shorted or power failure' error, could you please provide the reference Resistance (Ohm) and Voltage (V) values for the SSD DDR4 rail on a working EDM-044 board?


I want to confirm if the issue is a dead DDR4 IC or a failure in the power supply circuit. Thanks!" by the way, I have 1.2 V between SSD control and DDR4 on resistance.

The UART error 80810001 is only the info that in the power sequence error a switched on subsystem isn't responding to the southbridge.
For example: If you have a defect WiFi chip and the chip isn't answering, you will get the power sequence error and a specific error code 80C00136.

The power lines for DDR4 RAM are at the SSD pmic:
OUT4 -> 1.2V_FC_VDDQMIO
OUT5 -> 0.6V_DDR4_VTT
OUT6 -> 2.5V_DDR4_VPP

 

[BASHEER]

Update: I have confirmed that all voltages are present: OUT4 (1.2V), OUT5 (0.6V), and OUT6 (2.5V).


Since the power rails are now correct but the error persists, does this mean the DDR4 chip itself is the only remaining culprit? Or could it still be an issue with the SSD Controller?"

I checked your UART images and I don't get the sequence of events right:

UART 1:
10.04.2026 05:29 80830061 <-- Error unclear. (case of 80830060: Issue solved by replacing all GDDR6 RAM chips)
work done?
10.04.2026 11:54 80810001 <-- Power Sequence error (in this case: triggered by bad GDDR6 RAM chip)
10.04.2026 11:54 80801101 <-- GDDR6 RAM chip #1 is bad/has an issue
work done: Southbridge replaced

UART 2:
11.04.2026 01:36 80801F12 <-- GDDR6 RAM related. (Observations are going towards issue with reference voltages)
11.04.2026 09:44 80910002 <-- SSD controller boot EFC error (can be triggered by no power)
11.04.2026 09:45 80870003 <-- SSD controller boot failed (mostly no power/short issue)

UART 3:
11.04.2026 11:35 80871001 <-- SSD controller error (mostly no power/short issue)
