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 do
bringup
in order for the required voltages to appear, though...

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.

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.

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

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.

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.

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.

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.

I'm guessing an inner layer is either shorted or open. It's a needle in a haystack. It might be several needles in several different haystacks,

Not yet. Why ever do you ask, Anon?

Can you inject that voltage, or maybe a lower voltage, at the regulators creating those power sources and check if the power is getting to where it should?

He said the converters on the board are working, but they're being shut down at a certain point in the boot sequence.
>>
>>108994733
Start with the clock signal.
>>
>>108995276
I know. By injecting the voltage he could look to see if there are any devices not getting the power they need which could be what causes the syscon to abort the startup.
>>
>>108995399
I think voltages on SW_08 are more or less OK. Weird...

this is pretty neat, hope you get something figured out OP

>>108995285
Clock signal for what?
>>108996894
I have my hands full with bachelor thesis.
Currently I suspect that HDMI and VCE converter chips are just out and were the cause of the previous owner's frustration. I'm going to order a parts board from someone who attempterd a Frankenstein mod to try and replace the chips.

+1.5V_AVCG_VDDIO (Clock generator digital I/O portion power)
+1.8V_RSX_PLL_VDD

Now you're spending money. Just but a working board and swap it. Then you can work on the bomb PS3 in your spare time.
>>
>>108998836
I got the parts board for $7.
I can buy a working PS3 if I want to. I want to bring this board up for lulz.
And I don't have a scope (yet) to measure the clock signal.

missed something
>A0A02024 Occurred in a KTE-001 with a failed Bluetooth/Wifi module step-up voltage converter. A0002024/A0002124/A0003001 occured when attempting to power without 12v connected. A0A02024 also recorded. When 12v was connected the same codes would occur at step no. 09 instead of 00. 2024 replaces HDMI encoder, 2124 replaces AV, completed.
Needs more sanding around the wi-fi chip? Missing feedback to syscon from the voltage regulator?
>>
>>109000384
I would test a working console by disconnecting things one by one and comparing syscon logs. What happens if you try to boot a working PS3 without a connected display?
>>
reminds me of the time i found a ps2 slim that had clearly been stabbed through the board with a knife
/g/ was useless of course since you're all retards and i ended up throwing it away
>>
>>109001317
that would be an expensive and unfun repair if its in the middle and not an the edge
posssible nonetheless

Had no idea the PS3 PCB was so fucking big

>>109003455
It got smaller.

>>108974412
bruh is it still going?
>>
>>109003498
Yes, it is, even though it's hindered by the upcoming bachelor thesis
>>
>>108974412
reading through the thread, looks like you need a "board view" file to see where all the layers and traces are and where stuff is supposed to connect, legendary thread btw OP
>>
good thread bumpo

>>109003742
i think the anon probably already have it
>>
>>109003742
>>109003809
There is no such thing for my board unfortunately. There are leaked service manuals for some older revisions of the board and I'm using them already.

i'm a psycho
reverse engineered syscon firmware to understand what 8032 powerseq error means
this one literally reads "hello clock generator where are you i can't hear you"

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?

I'm prefacing this by saying I work at an S&P 500 Silicon Manufacturer when I say this; whatever you're doing at uni, stop and start taking embedded courses. The industry needs more people like you in it as compared to the slop engineers we're currently getting

Save your praise for when I get this board working. IF I get it working. Right now, I did nothing to deserve it.
