I managed to restore the severed HDMI_EN trace to the relevant Mitsumi voltage regulator and this got rid of the 2114 error.
However 2024 and 2124 pesrist. God I wish someone with a known working PS3 could measure the impedance on +1.2v and +3.3v going to the HDMI encoder chip.

What model PS3 is it? Is it one of the fat ones?
Would there be differences for those lines on different models? I have a fairly late slim one maybe I could open up but it might not give useful data.

Any model that has a MN8647091 HDMI encoder, CXM4027R video encoder chip, an SW2 series Syscon would be a huge help to me if you can find all similar voltage converters around the rear I/O converter chips and trace where their enable pins go to and, if possible, which output voltage they're designed for and what IC do thhey power.

This is a dummy plug guide, right? I don't think this will help since I'm trying to output video through composite right now.
I think I'm missing 3.3V and 1.5V on the CXR analog video encoder IC.
The problem is, which exact lanes am I missing? I don't have the service manual for a DYN-001 board, only for COK and SEM. I suspect that I'm missing +1.5V_RSX_VDDIO and +3.3V_ANA which prevents Syscon from talking to the VCE and enabling the voltage regulator that produces HDMI voltage lanes (something its programmed to do only if it can talk to the VCE? idk)

Thank you! I was trying to clear up a couple of things yesterday:
- what is the pinout of these bigger 6-pin voltage regulators?
- does this cluster of 3 voltage regs on the back side of the board power any of the converter chips, HDMI/analog? (pic related, 2 small regs produce +3.3V_EVER that feed the syscon together, what power lane is powered by the bigger one?
- What is that +12V voltage regulator besides the CXR video converter chip and what does it power? Where does enable signal come from?
- Main question: is DVE_VCC1 really +1.5V (+1.5V_RSX_VDDIO?) and DVE_VCC2 is +3.3 (+3.3V_ANA?) Where are these voltages coming from? Which regulators? What do their enable signals come from?
>>
>>108984162
Yeah, you can do impedance and probing without power on. In fact, doing it while the board is powered on will disrupt the meter because it uses voltage to measure resistance and continuity.
However, voltage measuring needs to be done on a powered board. You might have to press the power button or dobringupin order for the required voltages to appear, though...

Holy fuck, you're a life savior. Did you probe the enable signals? They might be coming from Sherwood or transistors connected to it.
This cluster of transistor is on the back side of the board, next to the huge hole and the +12V_MAIN power plug.

They seem to disappear into the middle of the PCB somewhere (tented via that doesn't have a trace on the other side).
They're all low resistance to ground as well, so my multimeter buzzes out any ground with them, but they seem to have the same resistance to ground, 26ohm, and under 1ohm to each other.
They are also under 1ohm to this pin on 304 501Y which looks like part of the power system for the RSX, but I don't know what it is yet.

Thank you. I cut it with a low power (18000 rpm to cut, not melt) gringing pen and sanded the edge with sandpaper of incremental roughness going all the way to 2000 grit. I was doing wet sanding with distilled water and cleaned the board edge with isopropyl.

I'm reluctant to power it because I don't have any way to really cool the chips, or a power supply to inject power with.
Kinda don't want to damage my PS3.
There is a second 33N205 on my board at least (one of the regulators in >>108985176 ) which is on a different enable line, maybe yours has another one as well you could probe to confirm that voltage.
A data sheet I found for BD35281 (closest i could find to D35287) suggests it has an output voltage of 1.2V, which may suggest that DVE_VCC1 is 3.3V and DVE_VCC2 is 1.2~1.5V
>>
>>108985301
Understandable. Thank you immeasurably for your input!
I'll make sure to document the voltages and regulators on PS3DW later after doing some testing on my side. I'm all out of questions for you now, let's hope your findings would help to bring this board up.

This isn't labeled as a 348A, but the pinout seems to match (I checked the connection to the SW).

Wait a second. I don't know what I was measuring here now. Using >>108985916 I get 1.1k ohms on HDMI_VCC2 and 4.4k on HDMI_VCC1.
I probably aren't qualified to be doing this.

>>108986044
I found that the VIN on the 33N205 feeding DVE_VCC1 is also present up on an 8 pin chip near the USB ports on my board. Probably 5V?
Probably quite a widely available power line, which means that the fault could be anywhere if it isn't present.

Baking the board will not help me here! It can only help with dead BGA connections (RSX, CELL/BE, soutbridge) which Syscon can tell me about with its error logs!
It can solve micro cracks in solder connections but I'm seeing none so far so I think baking the board will do me more hard than good. And I don't have an oven to bake it in.

I do not have anything like that on my board.
The closest candidate may be that chip down by F6300 and F6304.
Looking at a picture of your board on ps3dev, it looks like there is a second similar IC with similar components around it near the USB ports. I can't actually read the chip though, is it the same IC?

It does look like it is similarly laid out to the chip I mentioned in >>108988052 39A137 which is likely a DC/DC converter.
But there's only one on the entire board, top and bottom. I think it is serving the same role as this one here because it is connected to the CELL.

Though it is similar, it's a smaller chip 24 vs 28 pins, so I don't know the utility of even mapping out my one, even if I could.
Here's a closeup of it anyway.

It seems this DC-DC has the same role on my board, though I'm not entirely sure if that pin on the chip is an output or an input (ref?) on it.
Either way, it connects to the VIN of that regulator, other similar packaged regulators and a bunch of other chips on the board.
Not sure where the 3.3V is (thought it was the 12V for a minute there, then double checked).

>>108989109
It looks like the 902024 errors are likely a reflection of the 092124 or 002124 error?
Because step 90 is it trying to save settings from the HDMI (or other places?) if it fails to power them up and shuts down it will also fail to save.
Even if you don't want to use HDMI for now, it seems you might need to have the chip working properly to bring the system up anyway.

>>108989204
Yeah, this is exactly what seems to be happening. Going after the +5V_MISC and other voltages was probably a bad call since the DC-DC that controls it is probably not going to be enabled. I'm going yo RTFM tomorrow, double check my error logs and whether or not one of the trace repairs I've attempted actually set me back and prevented me from going up to step 9.

I've had some time to think about what I've done and how it affected power stages.
Turns out, the bodge wire to restore the connection to HDMI_EN on the voltage regulator was not only reduntant but it also prevented the syscon from powering that reg up.
Now I can see this voltage regulator output the required voltages for HDMI and I think the voltages for VCE/clockgen are created appropriately too but the console turns them off very quickly. I'm going to check all the voltage lanes that get initialized in step 09 for shorts and see if I'm missing something.

I'm not sure where to go with this board from here. I'm experiencing intermittent 2114 and persistent 2024/2124. The board never makes it out of POST stage 09. The board powers HDMI chip just fine and seems to briefly power VCE. So briefly that my multimeter barely registers a voltage spike. I did c
Could be three things:
- missing some voltage
- anons from the first thread were right and it's a power filtering issue (cracked mlcc?)
- something's shorting

please don't reply to them, this has been a progressive issue ever since /pol/ was instantiated. it's better to ignore them entirely. 4chan is a big place and /g/ is a relatively small board, so we have shitposts from other boards more often than is comfortable.

>Maybe you could get a bunch of buck converters and inject voltage where it's missing.
Current bucks work fine but the console seems to power them off abruptly on boot stage 09. I'm currently probing all of the analog voltages that are enabled by SW08 (boot stage 09). I'm using Felix's guide and leaked COK-001/SEM-001 (PS3 FAT) schematics.
That would be
A:
+1.6V_BE_VDDA (CPU analog subsystems positive voltage)
+1.5V_YC_RC_VDDA (CPU memory subsystems)
B:
+1.5V_AVCG_VDDIO (Clock generator digital I/O portion power)
+1.5V_RSX_VDDIO (GPU digital IO analog power, which also seems to feed CXM video chip)
C:
+1.8V_RSX_PLL_VDD
+1.8V_RSX_FBVDDQ
If I'm right, one or more of those are either short or missing.

COK and SEM used to have a dedicated switch (IC5005) that would enable/disable auxilary I2C line communication
This time however the separation is embedded in the TI clockgen chip.
I can confirm that SDA/SCL to this chip are continuous on my board but the switch IC5005 from COK/SEM had a dedicated enable line, maybe this chip has one too and it's missing due to board damage? Can someone with a similar board (Slim/Superslim, SWx series syscon and TI CDC971 chip) probe for it?
