The UART error 8087xxxx are SSD related. I would check SSD pmic for correct readings.

Thank you for the suggestion. I have thoroughly cross-referenced all the readings from the DA9081/RT5127 map you provided.

My Test Results:

• Standby & Power-On Voltages: All rails (\bm{0.8V, 1.1V, 1.2V, 1.8V, 2.5V, 3.3V}) are present and match the diagram 100%.

• Diode Mode & Resistance: All readings on the pins match the reference values perfectly.

The Core Mystery:

Even though the voltages are perfect, the console still triggers 80871060 (SSD Training Failure) and the SSD Controller (CXD90070GG) overheats within 2 seconds of the blue light.

Work Already Done:

I have already performed a full Reballing on:

1. Main PMIC (DA9065)

2. Southbridge (CXD90069GG)

3. SSD Controller (CXD90070GG

Is there anything is suspect?

I would change the SSD controller and see if it solve the issue.

Now , I have new IC Chipset CXD90062GG but on ps5 slim CXD90070GG , I think it should be the same model ?

stetofix · Mar 27, 2026

A 70GG is needed. The pad number is not the same. The 62GG is a 25x25 BGA and the 70GG a 23x23 BGA.

I found something very interesting regarding the resistance on the SSD data line capacitors:

• On a Working PS5 Fat Board: The resistance is 0.960 kΩ.

• On my Faulty Board: The same line reads 0.650 kΩ.

• Component Isolation: When I remove the capacitor and measure it out-of-circuit, it reads a perfect 1 kΩ. However, once soldered back onto the board, the circuit resistance drops to 0.650 kΩ.

• Deep Isolation: I have even removed all surrounding resistors and capacitors on that line, and the board still reads 0.650 kΩ.

The Question:

Is this 650 Ohm reading (a 30% drop from the working board) considered a "partial short" or internal leakage inside the CXD90070GG controller?

Since the voltage rails are correct but the controller overheats rapidly, does this resistance drop confirm an internal silicon failure in the SSD controller? Or could it be a leak toward the APU?

The board traces looks connected to the chip on the right side, i think it's ram for ssd.
I would try to remove both and do measure.

stetofix · Mar 28, 2026

The both marked components are 1 kOhm resistors. They are part of the voltage divider for the reference voltage VREFCA input at the DDR4 RAM chip. On your image the down side of the both resistors. My reading on that line is also 0.650 kOhm.
Heat is influencing the resistance measurement.

So I think that should be ok.

I understand. Since the 0.650 kOhm reading is confirmed as normal for the EDM-044 board, that path is now cleared.

My biggest challenge is the lack of a full schematic for this board, which makes it very difficult to verify every SMD component or specific signal paths.

In your opinion, does this make the SSD Controller (CXD90070GG) the only primary suspect left?

The voltages are all correct, but the chip overheats rapidly and triggers the 80871060 error. Does this confirm an internal logical failure of the IC? Or are there any hidden "Power-Good" or "Enable" signals I should check before concluding it is a dead controller?

After I verifying value , I find it OK and there’s no problem with the capacitor resistor. I’m still looking for the problem.

In my opinion the SSD controller is one of the most common issues if it comes to SSD failures at PS5s. And if no short on power inputs or signal lines is present, I would change the SSD controller.

There are schematics for edm-010 and -020. This informations could be used with some measuring/searching at other boards like -03x/-04x/-05x.

To keep the messages clear:
A resistor reduce current flow and is measured in Ohm. If broken, interrupt the connection between both sides. (<-- simplified)
A capcitor stores electrical energy and is measured in Farad. If broken, acts like a wire. (<--simplified)

I have successfully replaced the SSD Controller (CXD90070GG) using a donor part. However, the error code has now changed from 80871060 to 80810001. The console still powers off after 2 seconds.

Observations:

• Old Error (80871060): Was related to SSD training/logic failure.

• New Error (80810001): Appears to be a Power Sequence Error (General Power Failure).

• Before the swap, I had all SSD voltages. Now, with the new IC, it seems the power sequence is being interrupted.

The Question:

Since this error appeared immediately after the IC swap, does 80810001 specifically point to a short circuit under the new BGA chip or a specific power rail (like GDDR6 or APU) failing to stabilize?

Could this be caused by a minor soldering bridge under the CXD90070GG, or is there a specific 'Power-Good' signal that I might have interrupted during the process?

If now with the new SSD controller voltages are missing, there maybe an issue with the chip or the soldering. It is possible that bridged BGAs could be the cause.

Which voltages are not present at the SSD pmic?

Hi,

I’ve checked all the standby voltages that I’m familiar with, and they are present and stable.

Is there any specific voltage rail or IC that you recommend I should verify next? Also, do you happen to have a datasheet, boardview reference, or even an image showing the exact measurement points and expected values?

Also, I checked the RT5127, and all standby voltages are present.

When I press the power button, I can also briefly measure the rest of the voltages — they do appear for a short moment before the console shuts down.

Also, I found a point on the board (as shown in the attached image). Between these points, I’m getting continuity — would this be considered a short, or is it normal behavior for this circuit?

DA90065 could be the problem ? All voltages good but maybe

he’s probably ? Or not.

Do you have the entire UART error code string for your new error codes?

|-(OK 00000000 80810001 FFFFFFFF FFFF0023 10000100 204A 0036 FFFF 1736:E4)

Yes, I have

stetofix · Mar 31, 2026

00000000 80810001 FFFFFFFF FFFF0023 10000100 204A 0036 FFFF 1736

204A = Sequence number: SoC is not responding
FFFF = SoC temperatur: SoC is not getting warm --> not powered

I guess you solved the SSD issue and now the southbridge gets past the previous SSD error and now stucks at the next issue.

Now the hard part is to find the issue why SoC isn't turning on. If you try to power the PS5, there should be voltages measureable at the SoC power rails. If not powered, the low impedance lines will show up as shorted. So it is a bit tricky to find the missing SoC voltage, if it is a case of missing a power line.

"Upon power-up, thermal imaging shows high heat on the RAM and CPU. The system trips after 2 seconds, returning to a standby current of 0.010 Am

The IC gets extremely hot immediately upon power-up.

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.
