PS3 Fault finding YLOD with the SYSCON - First steps and Error reporting

Forget it, if this is apparently an RSX issue, is it even worth trying to fix. I have no problem attempting to delid, or replacing capacitors. Obviously if it requires a major expense like reballing its not worth it. But I have zero idea about any of this which is why I was asking to begin with.

So much conflicting information with people, ugh.

Sometimes certain information gets misinterpreted, or miss read.

This whole thread is about learning and getting ideas, I just my first attempt in guiding on what I found and know so far.

Others have contributed and found other faults and then learnt new techniques.

So, really it boils down to the approach and expected result at the end.

Don't be disheartened, its a long road. We cant all get it right first time - I know, 4 x trashed ps3 boards still haunt me to this day.

But what you can get out of it is a better understanding and know when to proceed or not.

Will regular 16 AWG wire work for the breadboard shit? I've got a ton from my custom PC cables. Other than that I just need the adapter.
Also, I've been watching videos on the de-lidding but is there a certain tool/etc I should be using for that to make it the easiest it can be? (Which is obviously not easy regardless)

In terms of cable, its best to get AWG 30, reason being the solder points for the syscon are tiny and can be prone to lifting with too thick cables.

So what you need for starters:

Find what model of ps3 motherboard you have:

Only FAT models can be fully understood at the moment - CECHA,B,C,G,H,K,L

Look at my guide for pictures on where the syscon points are located, depending on the board.

Then you will need these parts as a minimum.

1x Soldering iron with small tip
1x Solder or solder paste
1x Tweezers
1x Cutter for wires
1x USB ttl 3.3v serial lead - https://www.amazon.co.uk/PL2303TA-U...qid=1617547131&sprefix=usb+ttl,aps,165&sr=8-6
4x AWG 30 cable about 0.5 metre in length, soldered at both ends

Each awg 30 lead will be as follows:

Label them up, 1x RX, 1xTX, 1xGND and the last as 1xDIAG (this just gets connected to the GND to set to low imedence)
Solder RX to the RX point on the PS3 board - repeat for the TX and GND (GND going to GND point on the ps3 motherboard)

Then you will need to follow my or others guide to talk to the syscon - there are a tool for windows users in the same repo

Thank you... unfortunately I have already checked and replaced all blown fuses... could anyone help me buying ic 5001 (its code is ICS 6320959 0650 1493G18LF) or checking for other issues related to 2120?

PS
I have also changed the crystal with a known good one.

An RSX issue is game over/pointless to try fixing is it not?

If you don't have the equipment and experience to reball it, yes. Even then, the success rate isn't 100%. @squeept just reballed a sealed A01 motherboard I traded him. It had a single 3034 (RSX issue)...
squeept said:
...@RIP-Felix Your board reballed to GLOD with A0801001. All other checks normal, and I replaced the caps just in case since it was otherwise such a perfect candidate. So I think that means bad GPU, which then means your board will have the distinction of being the first 65nm swap I try out.

Hello gentlement, i have a bunch ps3 boards to test and fix already 2 with nec reemplacement, but like many advice is better know what kind of error board has before; reading about syscon usb to ttl serial cable v3.3 i looking on my country for the cable adapter and only find this, my question is this works too, with generic jumper cables? the datashet says genereic brand model: Cp2212, minimun input voltage 5v - minimun output voltage 3.3v - 5v ? thanks before hand. https://articulo.mercadolibre.com.c...cking_id=4b0d1065-cea9-45e2-9ad7-20fa10f90b5a

What's important is that the RX/TX lines are 3.3v. If they're 5v it's going to fry the PS3's syscon and brick the board! So be sure thet the adapter is the 3.3v version. Hint: if it says it's for raspberry pi, that should work, because Pi's are 3.3v. Whereas an Arduino might be 5v.

PS:
I like your handle!

sellers dont say anything about raspberry, so i find the datasheet from adapter chip CP2102, looks like is 3.3v, i going to order and test in a faulty/junk board (safe bet if i wrong), thanks. link to complete chip datasheet https://www.silabs.com/documents/public/data-sheets/CP2102-9.pdf

You can just check voltage with a multimeter. I think I mention this in my guide.

Red probe on Rx or tx
Black probe on ground

If it's 5v or something other than 3.3, just don't use it.
Should be around 3.3v
 
Where are the test points on a KTE-001? Just broke down a 3001A that won't PWR on. Tried a new PSU, but same behavior. The red led lights once when I plug it in, then goes off a second later. PWR BTN has no effect.

I did buy this console cheap and to harvest it's RSX for a frankenstein swap, but I may as well see if I can fix it just to make myself fell bad when I rip it's brain out.

Rsx should have 2~ 3 ohms on power line, cpu about 3~4 ohms (not 8).
Power line of rsx ram should be fine with 400 ohms, if twisted multimeter will get 470 so is same (ram power line of rsx is with blue on corner).

Just to remember what tests I've made
http://s.go.ro/sb13pvd1
On this phat models if test like me on end you hear 3 beeps is signal of overheat so that point quick turn it off.

i confirm adapter with chip CP2102 works; testing next board cok-002 1-2 seconds delayed ylod, enabling "internal mode" (using git guide changing eeprom value) "auth" and run command "errlog" give me : a0403034 - a0404422 and finalize with [mullion], checking back post is more like RSX bad connection = reballing is advised, @RIP-Felix felix: in your test, is required assemble all ps3 ? can alter errlog results ? i test that board semi-assembled metal cover - hdd - bluettoh module and board withow metal cover no hdd - bluettoh module and give me same result.

second board COK-001 only error a0313031, has cell - rsx delided, looking error id syscon git, looks like related cell, someone has some info-experience with this error? meanwhile checking physically board if something is off.

Hi All
have to say im a big fan and iv read alot of this thread after discovering the PS3 Syscon project a few months a ago

i apologize if this has been answered before but i have tried finding it and cant seem to locate anything specific and im out of ideas on fixing this one

its a CECHC02 with YLOD the syscon output points to a HDMI chip error, i have checked all around the chip for faults and can find none, i bypassed the Termistors on the 5V rail still nothing the HDMI bus to the RSX chip has no issues i can find so short of randomly replacing chips till it starts working i am at a loss :/

here is my boot sequence output, i can't locate the error 3013 but 3012 and 3020 are IC1001 (CELL Processor) so i assume that's what it means but it follows a bunch of HDMI chip errors so im assuming the CELL cant detect it and shuts off

any help you can give would be really appreciated i would love to get this old girl back online :)

Look at the service manual, you can use a multimeter to test the signals from the RSX to the hdmi encoder chip. Just watch for voltage changes.

Another way is remove the hdmi encoder and see what syscon errors occur, if its the same errors then I would say thats the issue.

But check any voltage readings around the hdmi encoder area, the CELL errors are mostly likely related to no response from the encoder.

Encoder chips are available on ebay, bought some last year.

There is the hdmi command in the syscon, see if it sees the encoder chip
 
"second board COK-001 only error a0313031, has cell - rsx delided, looking error id syscon git, looks like related cell, someone has some info-experience with this error? meanwhile checking physically board if something is off." looking this seems after delid CELL has some subtle scratch maybe this is the problem; third board a COK-002 only error A0093004 RSX_POW_FAIL already test another PSU, change some Necs, but nothing only this error, appear, someone has experience this error? thanks.
 
Welp just read the syscon of a 3000 series slim. It shuts down after 30 odd seconds with GLOD symptoms kinda interesting.

However it has codes that i dont think are documented yet "A0805FFF" nor do i have anyclue what they mean, nor do i know of any prior.
history of this console. However due to the fact its shutting off after 30 seconds im suspecting maybe some kind of nor corruption possibly?

Thanks for the responce :)

i did check the voltages but didnt think of looking at the error after removing the encoder or checking for a Syscon command for the HDMI chip

i have swapped out the chip from another board but i think il buy one new just to make sure it works properly (and has the correct solder ammount between it and the board) :)

il post back and let you know how i go
