#94 Repair of PS5 Beep On-Off

[@calhoupe]

There was likely one bad RAM chip that failed immediately from the factory, which caused this PS5 to fail QA. Your attempt at reballing worked temporarily. Obviously, replacing all the chips solved the problem. It’s too bad we don’t have something similar to MATS for Nvidia graphics cards to be able to pinpoint which RAM module has failed. Even replacing all 8 RAM chips with new preballed chips is time consuming. This was an impressive repair. Your perseverance is remarkable!

[@ToltecMerc]

It was quite time consuming. I need a way of testing them individually.

[@B9NE]

The Cod3r on KZbin knows a ton about ps5s. There's a bank of four caps that's common to blow and several voltage regulators. His PS5 series is pretty thorough. He was able to switch a system from disc edition to digital.

[@ToltecMerc]

I am very familiar with @TheCod3r.

[@shakangel666]

Amazing perseverance, knowledge and patience!!! This type of troubleshooting documentation is worth gold and I'm sure you know that hours spent on whatever doesn't yield a repair is not a waste of time. Congrats on yet another successful repair.

[@ToltecMerc]

That's very kind of you. Thank you so much!

[@abrahamadekanye5714]

Great job, was expecting you would use your thermal camera to pin point which of the ram ic was not working well. Either over heating or not heating up. Great job at the end. Your persistence was over and beyond.👍

[@toolsarecool]

Another brilliant display of skill and tenacity leading to results. Glad to see that what was probably multiple hours of work leading to solid results. 👏 👏 👏 🔥

[@ToltecMerc]

It was a lot of work but, as I've mentioned, these belong to me and I've invested money in them so I am motivated to fix them. Plus, as a hobbyist, I can take all the time I want!

[@godidiful]

Thanks so much for sharing your knowledge once again! Perseverance and tranquility are examples shown by you on your laboratory bench! Congratulations…

Last weekend my launch model PS5 made a loud POP sound in the middle of a firmware update and then went completely dead. I took it apart and found the power supply was not showing 12V. So I swapped in a working PSU from my brother's console and luckily got my PS5 running just fine, despite my concern about it dying in the middle of an update. Had to give his PSU back so I bought a new replacement ADP-400DR from eBay, gonna give it a try tomorrow but I'm worried about it looking a bit different from my original one, hopefully it's a genuine part. Anyway, I'm glad I found your channel after my sudden PS5 disaster, you've really given me hope for my dead console (especially since Sony wants $230 to repair an out of warranty console with a no power symptom). Keep up the good work!

[@ToltecMerc]

There are knock-off copies of the PS5 power supplies, particularly the ADP-400FR. I have not seen one of the cheap copies so I can't say if they work well or not.

[@SirCharles.]

@@ToltecMerc the biggest difference I've noticed is the Sony labeling is missing the bottom half (the part that says CQC and all the Chinese text), the components visible through the holes on the AC input end look very different both in size and positioning, and lastly the 2 screw holes where the PCB is visible with all the small C-shaped solder markings around them (the little C's have a lot thicker solder than the "new" one).. also the new one came without the foam spacer strips on it. I thought I could chalk all the differences up to changes by the OEM over the 3 years from my launch model unit to this replacement being made. With part shortages and overall design & efficiency improvements perhaps things could've changed but I'm still concerned because the eBay listing had pics that looked more like my original with the full text and the foam strips. I saw in one of your videos you had a PSU missing the CQC text but it was a 400FR model. And while searching on eBay I saw some with a sticker in the place of the Sony markings, but I purposely avoided those.

As the saying goes I take my hat off to you. Good learning from this. I have one exactly like the video #90 1 single beep no light,digital version sent in by a viewer of yours. Mine same board, disc version edm020 no shorts at all and I was thinking of ram. Now re watching the #90. I am going to change the SSD controller like you did when I will have some time and see how it goes.

[@ToltecMerc]

Good luck! Those SSD controllers aren't cheap!

[@mm0077]

@@ToltecMerc I have got a few donor boards.

[@TechCommanderRepairs]

I commend you, reballing those RAM chips without a stencil is tedious. I've reballed PS5 southbridge chips and that is hell

[@ToltecMerc]

Thanks! I have a stencil now but I still have not gotten the hang of using solder paste. At least with the balls, I get consistent reballs every time.

[@Doctorapplerepairs]

@@ToltecMerc what size the balls

[@Derricky007]

At the end nice work. But my main question is, why are you not using a preheater ? This way your bga soldering will get next level. One zone heating is known to produce often insufficient heat transfer. If you consider the thickness of the board and the surrounding copper planes, don`t you think that the heat will draw away ? Your hot air station is good, has enough power, but with 2 zone heating it is another level. Another thing is which is crucial in many cases, you have to adjust your temperature and airflow almost or to max to get the solder balls melted. To much heat and a longer heat stress test. With a nice preheating profile, you can lower the max temps significantly.

[@ToltecMerc]

You are absolutely correct! I do have a pre-heater now and it makes the work much easier and I am able to use less heat on the chip. Please check my more recent videos.

[@Derricky007]

[@ToltecMerc]

Thank You! Come on back any time!

[@RcFixer]

impressive work done. with so many chips it is preferable to use a stencil. this oxidation always occurs with lead-free solders, only reball solves the oxidation. reflow only repairs the microcracks in the balls, there are few chances on the ram, the microcracks are mostly on the cpu where there is pressure. all the best

[@ToltecMerc]

I have a basic stencil but I'm not sure how well I like it. It's hard to get consistent ball size. I have a better magnetic stencil ordered.

[@Console_Tech]

Again another amazing video. Genius work .

[@andreasponchiado8839]

Man please give me 1/1000000 of your patience 😂 i can see myself doing this with 1 chip not with 8 Keep It going you are making great video!

It is time consuming but I like the results. Balls are very consistent.

[@John-oo9xu]

Good job, have one myself at the moment with exact the same symptoms. Gonna reflow the ram first, hate to reball 😮

[@ToltecMerc]

Best of luck to you. You may have to reball though.

@@ToltecMerc Thank you, i ll keep that in mind. Love yoir channel, no bs and good skills in fault finding.👍

[@anthonyboccardo2726]

Nice one mate, would be handy to know the outcome after more extensive hours/tests put in, maybe after a week or 2? I wonder if u just had 1 or more rams failing and that was the cause? replacing all of them makes it harder to know but this is where UART much like the PS4's will be needed some day.

[@ToltecMerc]

I've been looking for a RAM tester. So far everything I've found is stupid expensive.

[@Topsecrettechstx]

Nice informative video, thank you for that you do. What temperature do you remove and install the RAM chips?

[@ToltecMerc]

Thanks! I used 420C.

[@themanieq]

Impressive and incredible work. 👏👏 Maybe only one ram was faulty and you could spot it with thermal camera.

[@ToltecMerc]

It is possible but I had seen similar gray pads under RAM on another board. I feel like the only way to be sure I got every one is to reball all RAM with lead solder balls.

[@themanieq]

@@ToltecMerc Yes, it's the only way to be sure.

[@frazerxavier7295]

That's oxidation on the ram chips. On graphics cards it's the same thing. I have to remove it and reball it and it's back to normal.

[@ToltecMerc]

That's good to know! I have seen it before on chips but I wasn't completely sure if it was a real problem or not. It's definitely a real problem!

I am not sure either but I think they are either 2.5A or 5A. They seem to use a mixture of those two values but I can't be sure.

I guess GDDR6 STENCIL is in your shopping cart shortly😄

[@ToltecMerc]

My stencil just arrived. Now I have to practice reballing with solder paste.

[@t3k2]

I would say, try both methods (balls/paste) and decide witch works better for you! I've found using balls with stencil giving more consistent results, to my liking. Paste, it it has too much flux, gets bubbly and the balls just merge all over!

That’s really wierd. Why doesn’t it turn on immediately… maybe the board was still too hot, or Interference? After reflow you are back to beep on back up, my guess would be the APU had a indirect reflow too? NVM 😂 ram chips.

[@lestermoreno9437]

how do you test the RAM Volts to know that the voltage was dropping

[@ToltecMerc]

You can look for the ceramic capacitors mounted around each RAM IC. Check the voltage across them and see if you get 1.35V momentarily on power on.

[@antoniopetrillo4530]

Hi, was it crashing during game? Then it asker you to report or not to sony? Thanks, great work🎉

[@ToltecMerc]

It would crash at random time. No message on screen. It would just freeze and drop back to the desktop. Also, the audio in a game started getting distorted.

hello and congratulations My playstation 5 turns on and off right away I saw that it doesn't have any capacitors shorted but it has the R22H neighbor coils next to the processor shorted. Is it normal for them to be shorted? I'm starting to think too that the problem might be reballing the ram...

[@alicehops]

I currently have a PS5 that is experiencing what happened to this one, what would you recommend to fault find to know if its the ram or not? since im not experienced in reballing and would like to know if it definitely is the issue before attempting the fix

[@ToltecMerc]

All you can do is try to eliminate everything else such as shorts on power rails that only come up when the console is fully powered on. I noticed the fast shutdown when I was working on a PS5 that I powered on while one RAM IC was removed. I noticed it shut down immediately and I made note of that. Bad RAM can cause all kind of weird behavior. It all depends on what part of RAM is not accessible I would guess. I don't have a magic way of determining if RAM is the issue. Sorry.

[@douro20]

Are they special memory chips?

[@ToltecMerc]

They are GDDR6 RAM ICs. They are available but not inexpensive
