Wollte eigentlich nur eine Pad-instandsetzung sehen aber das Video hat mich ein wenig hypnotisiert :D So ich durchforste dann mal den rest deiner Videos

[@stetofix]

Viel Spaß beim Anschauen. :)

[@MrLasox]

Thanks alot very good video. I like that you are using text instead of the voice or music. Alot of these repairs people are talking too much and that you explain everything you are doing is amaing because i'm just bhought my self a reapir system so i'm about to start it my self so learning step-by-step how to reballing is very useful. I have seen hundreds of videos about doing repairs, but this video has too be the best one so far. Even though you didn't fix the issue, but you showed alot of issue too fix in details.

[@stetofix]

Thank you.

[@davidstrider2007]

Nice job stetofix. Wish my work bench was that clean hehe. :) Nice content. I subscribed. Keep up the great work. :)

[@stetofix]

Thank you. :)

[@andrewmeikle785]

@stentofix thanks again , I have a reflow unit but my experience on APU is limited ,however I will try and reflow to see if it comes back to life , if not I may even try a relball if it fails ,will keep you updated and perhaps we could put a signature on that error 👍

[@stetofix]

Would be nice to know how it turns out. :) Fingers crossed.

[@edwardekiert4790]

Is the HDMI IC really that expensive? Also, have you checked filters on HDMI lines and capacitors around IC for shorts?

[@stetofix]

The HDMI ic costs atm aprox 40€ itself. And the customer desides not to put more money in this repair. After reflow the HDMI ic, I tested the caps, filters and HDMI port. All fine. There is an output at 480p in safe mode but when resolution changed to 720p or 1080p the screen stays black. If the customer would have agreed to continue, I would have changed the HDMI ic. But it is always a risk if a board has privious repair attemps and could end up in a rabbit hole.

What is the name of your preheater? (In 10:49)

[@stetofix]

It is a Aoyue Int 853A Pro

[@jazero-u7p]

I appreciate your videos. I wonder if you have come a cross this, UART shows DRR4 issue. Is this near the ssd controller above as only 1 there. I understand ps5 has DDR6 not DDR4? What is your take on this. Can this DDR4 be changed from another board or game over? Can you change 1 RaM with other the make from diffent ps5 board. I have seen people changing them with same Ram. It so not clear whether this can be done.

[@stetofix]

Thank you. The one single chip for the SSD controller is a DDR4 and the eight main RAM ics for the APU are GDDR6. You can replace every single RAM ics with one from a donor board. The only thing the eight GDDR6 RAMs must be the same brand/type and can't be mixed.

[@jazero-u7p]

@stetofix Thank you very much for your reply. What about that 1 DDR4 can be replaced by a good donor board?

[@fu1r4]

Thank you for not having any background music! 👍 No donor boards to take from?

[@stetofix]

Thanks you. Background music would more distract me while I'm troubleshooting. For monotone works like placing hunderts of solderballs on an ic, I sometimes hear podcasts with handphones. So it doesn't appear in my videos. I have some donor boards for parts. Sometimes I prepare some ics in advance.

[@andrewmeikle785]

@stentofix , just a quick update re my last question after playing with the board a bit I found that if the Apu clamp was released it would stay in BLOD so i conclude that the problem is the APU as on reapplying the the clamp the iboard will boot to white but then turn to pulsing blue. and abit of a query about the Uart rtc if you know , I was reading inthe forum that there should be a time stamp after every error is that correct, did you manage to find out if thats correct if not is the southbridge at fault thanks in advance 👍

[@stetofix]

It sounds like a reballing for the APU is needed to fix the contact problem. Yes, the second row after the eight digit error number is the time stamp. If the battery is taken off, the time stamp will always starts at 00000000.

[@andrewmeikle785]

@stentofix , thanks , can I ask,is it possible to get error code with no timestamp but with attached good battery ,which sounds contradictory , but would indicate some fault relating the the southbridge tks

[@stetofix]

Yes, it is possible to get errors with no time stamp. I just saw some error codes with no time stamps. (gbatemp.net/threads/ps5-uart-commands.642741/post-10342695) They are all Exxxxxxx errors and may indicate problems with southbridge or nor, as you wrote.

[@dan_1150]

What temp do you set your preheater for this?

[@stetofix]

I try to get 150°C in the pcb where I want to solder. The setting for the preheater is a bit higher (~200°C).

[@moioi3563]

I thought the SSD controller chipset was married?! This is not the case, can we change it then?

[@stetofix]

The ssd controller is exchangeable. Three of the six ssd ics are no exchangeable, because there is unique data on it.

[@moioi3563]

so there is the nand ssd which contains the firmware, what are the other two non-interchangeable chips please?@@stetofix

[@stetofix]

There are three ssd nand ics which can not be swapped. If they are swapped, the PS5 will not turn on anymore. On ssd controller side the single one. On the backside the both in the same orientation.

[@stetofix]

The Errorcode 808C3090 is a USB C problem. Please check the lines and ics in the USB C ciruits.

[@SuperEmil2010]

@stetofix OK and it won't let you install any system software, is that normal?

[@stetofix]

@@SuperEmil2010 I don't know if it is normal. The error code is pointing towards the USB C ciruits. I would make sure that the readings at the associated chips and lines are fine again and than move on to other issues. Some problems with core features (bad WiFi/bad disc drive/bad USB/...) can cause a PS5 to not(re) install any firmware.

[@jonathansandiford4137]

which hot plate is that you used for reballing the southbridge m8? looks sooooo much easier than using hot air!

[@stetofix]

It is an old version of 'Mechaniker IX5 max mini'. I like this method very much, because I struggled in the beginning very much at reballing Switch SoCs with magnetic holder and solder paste or solder balls. So I tried placing the solder balls with a stencil, take the stencil off and place the ic on that hot plate. Now I'm using this method for mostly all bigger ics.

[@jonathansandiford4137]

@@stetofix nice. I use to struggle with the stencils before, but my main struggle now is using hot air to get the balls to flow. Most times they move because of the airflow, and get merged. Too low of an airflow and it takes too long, too high and the balls move around. I will try the hot plate method. Thanks!

Hi like your videos very informative , have been playing with Uart but none of my error codes seem to match anything that I have found . Have been following J D tech and I was wondering where to find the SSD ram chart that shows me what chips I can change 2 on one side 1on the other perhaps you could help tks

Hi. Thank you. Replaceable are the both ssd ics with same orientation on the ssd controller side and the single one on the backside.

[@schadowman89]

Top Video. 👌 Ich hab mal ne Frage: Ich habe mir auch WEETOOLS und nen Programmer besorgt. Leider erkennt mein PC nicht den Serial Port USB. wenn ich aber den WINBOND direkt auflöte und mit dem Programmer in den USB packe dann kann ich den chip auslesen. Also Programmer funktioniert. Hast du noch nen Treiber oder so für WEETOOLS installieren müssen damit er erkannt wird? Danke schonmal im Vorraus😅 😅😅

[@stetofix]

Wenn der Programmer nicht zum Aulesen des WINBOND Chips sondern zur Kommunikation mit der Southbridge genutzt werden soll, muss der Programmer auf TTL umgestellt werden. Beim CH341A ist auf der Seite ein Jumper der von 1-2 auf 2-3 gesteckt werden müsste. Dann sollte es mit der Com über RX/TX funktioniren.

[@schadowman89]

@@stetofix Saugeil für deine schnelle Antwort. Werde ich morgen gleich mal ausprobieren. 👍 Bin übrigens jetzt schon gespannt auf ein neues Video von dir. 😎 Vielleicht kannst du ja ein paar Temperaturen in dein Video packen. Nutze übrigens auch nen Vorheitzer. Dadurch wölbt sich das Board nicht so und es benötigt weniger wärme von oben.

@@stetofix ok danke. wenn ich nun löte, haben meine lötpunkte immer so eine spitze oben drauf und sind nicht rund und flach wie die originalen lötpunkte. woran liegt das?

[@stetofix]

@@onehitwonder4470 Es könnte an fehlendem Flussmittel liegen. Mit Flussmittel oxidiert das Lot nicht und der aufgeheizte Flüssigkeitsfilm sorgt für ein 'Perlen' der Lot-Oberfläche, was beim Abkühlen runde, glatte und sogar spiegelnde Lötstellen bewirkt.

[@onehitwonder4470]

@@stetofix komisch. war schkn alles voller flussmittel. macht das bei no clean was aus, wenn das auf dem board bleibt? hab da zwidchen den komponenten richtige dicke schichten ab und an. schwer zu beschreiben.

[@stetofix]

@@onehitwonder4470 Bei No clean muss das Flussmittel nicht zwingend vom Board gewaschen/geputzt werden, da es nicht die Leiterbahnen korridiert. Zum Löten trage ich frisches Flussmittel auf die Lötstelle auf und wenn der Lötkolben genug Leistung hat, sind auch große GND Pads kein Hinderniss für 'schöne' Lötpunkte.

[@andrewmeikle785]

Hi again thanks for the info I have used uart to guide and get error “80C00140” according to your excellent List it is APU Freeze and Referes to DDR 6 Can you clarify it is ram replacement ,not APU . Many thanks for your help👍👍

[@stetofix]

'80C00140 APU Freeze (No Response) - GDDR6 data line problem (replace)' refers to a data line problem between APU and GDDR6 RAM ics. But I don't kown if the com is interrupted at the APU or and one of the GDDR6 RAM ics. From my point of view, it could be a broken trace/solderball under the APU or one of the GDDR6 RAM ics.

Sad, I feel for you, I had a dead PS5, fixed the power supply and it was still dead, replaced the southbridge and it worked. I thought that was it but the console won't update, now I'm waiting for the SSD controller, I think that's the problem. I've never done a UART check on a PS5, I have a CH341A, maybe I could do that too. Basically, I wish us better luck next time 🙂

Thank you. I hope that new SSD controller will solve the update issue. 'fingers crossed' With UART I added more informations to a case. Not allways usefull, but sometimes like in this case pinpointing the defect exactly.
