Buying FAULTY PS5's on eBay - Can We Fix Them? S1:E65

[@EDOD_EseDelOtroDia]

That second PS5 turning off after a while, it seems to me like it has a faulty capacitor. Not a "shorted" capacitor, but a DEGRADED one related to the APU directly. The APU stops responding because the faulty capacitor is falling short of the capacitance it would need to stabilize the voltage going into the APU, so when there's a moment when the APU needs that energy and the capacitor is not delivering it in time, then there's only "dirty" energy going into the APU. So the APU becomes unstable and so the data inside gets corrupted. Causing a kernel panic. Also, the "unexpected power failure" can also be related to a capacitor because of the same reasons. I would look at the capacitors in the phases and/or replace the power supply for a known good one for testing.

[@EDOD_EseDelOtroDia]

It could also be the MOSFETs driver now that I think about it. That would take into account that only some phases seem to be talking all the load. That uneven heat could be the key to that

[@Barteks2x]

My first thought when seeing that error was "replace the capacitors", next try a different power supply. This sort of intermittent issue under load with various power related error almost screams unstable power source somewhere.

[@ToltecMerc]

That second PS5 was quite odd with those bottom two MOSFETs seemingly working some and then not at all. I wonder if there could be a drive problem between the phase control IC and the DrMOS. Those six should be working in parallel to supply the massive current needed by the APU. I wonder if the APU core voltage is sagging because those MOSFETs are not helping. I wonder a lot. Great job!

[@carbonblackprod]

you're here

[@caseycornett5182]

This was my thought. Need to get a scope on those supply voltages and look at the wave forms. Really odd issue.

[@mrjarto]

I’m with @toltecmerc, it seems that the control IC in not sending the proper PWM to those DrMOS

[@ivo642000]

with the second PS5, it can be a bad PSU, even though its reporting 12v rail, under stress it can fail, i have had PSU that do this 100%

[@denman123456]

Was just going to mention that it might be a dying psu.

[@simonupton-millard]

Could we be voltage dipping when it has a load had this with a pc with a dying psu, could do anything fine till the GPU had a load then BSOD

[@ivo642000]

@@simonupton-millard its shutting off right when the APU will be drawing max power on the main menu of the game, its got to be the PSU imo

[@ivo642000]

i would love to see you transfer the APU and married components to a donor board, from the smoked PS5

[@klorslug]

I agree with a few other commenters about trying an known good PSU on the 2nd PS5 to see if the PSU is having intermittent faults

[@PeterFalconII]

Misfits will pulse heat if there's some low resistance on another part of the board down from the mosfet. tvs that pulse normally have a bad diode or resistor on the output side. This can cause intermittent faults shutting the system down randomly.

[@sasiuru]

The Magic Smoke has well left from that first PS5. Big time.

[@Kakusuo]

Second one might be repairable, definitely take a chance at it again.

[@mihai.seba23]

Don't have experience in repairing electronics (just on embedded devices, debugging) but on the second PS5 I would check those capacitors and the phase control IC. Probably a scope would have prove useful.

[@thadofalltrades]

I hope Joey takes another look at the 2nd one. It's infuriating that the seller of first one knew it was that bad and didn't disclose it. So dishonest.

[@thadofalltrades]

@@MyRegardsToTheDodo Joey obviously didn't know there had been a small fire so that wasn't disclosed unless he just bought it without reading the description, which he's done LoL

[@thadofalltrades]

@@MyRegardsToTheDodo that's the thing though, on eBay there's not a "faulty" category. It's just "for parts, not working" even if it's fixable. So they technically don't have to disclose anything. I find that dishonest personally if they know what's wrong with it. It's like the ones that sell heavily water damaged units and don't disclose it, knowing it's water damaged. Now, you're right, the lower cost shows they are least weren't trying to rip someone off.

[@sj55]

Joey I had one doing the same thing and once the new update came out I updated it and its been fully working since

[@SweetLou814]

I started using the Better way Electronics UART reader and it seems a little more detailed then googling the codes. I am also curious if the Ram has an issues. I watched a video of Toltecmerc where his PS5 was stuttering and not running smoothly and replacing the 8 RAM chips did the trick. Worth a shot

[@Unjustself]

I agree with a lot of comments: check the power supply. I had a pc that turned on fine, would load games and then randomly shit off (especially under stress). After checking every component it turns out my PSU was dying and would shut off under stress..new PSU and problems went away

[@leorelic]

what are the chances the second PS5 had a faulty PSU?

[@brando12343]

that’s my guess too, in my experience faulty power supplies will sometimes work fine to boot and do basic tasks but the second you try and do anything intensive it shuts off

[@meszarosmate4629]

It can definitely be the problem, my PC was booting up but no output to the monitor. I tried to change cables, use the VGA ports instead of the DVI, tried without graphics card, using the motherboard outputs, nothing. The pc was running perfectly tho. Turns out my PSU crapped out and didnt deliver enough power for the gpu(its an old 1050, no powerhouse needing 300W) or the apu, replaced it, been working fine ever since. I guess my point is that if you dont give a system enough power it will act up and obviously different systems have different priorities for power, thats the nature of physics. Its definitely a possibility that APU starts draining more power when launching fortnite and the system cuts off.

[@JJ21lives4ever]

Not sure if he is using a donor chassis but if not then yes, definitely test with a different psu

[@jamiecruickshank9697]

That’s what went through my mind too, it would certainly be worth a try.

[@sliseofrandom]

I was thinking exactly the same. Bad PSU

[@RepairMan00]

The flashing of the second mosfet suggests to me that something in that area is failing. I would strongly suggest replacing all the caps on the 2 bottom mosfets to rule it out. Apart from that as others have suggested could be power suppl,y especially considering the randomness of the errors in uart. 2 things to check.

[@Effect2o]

I think its crazy how the brain works, cause I SWEAR I could smell it when you lifted that away to reveal the burnt area. WOW!

[@BoomerTech]

I would definitely try that second ps5 with a different PSU, could easily be a power dropout on the 12v supply, would also explain the lack or pulsing of power on the lower mosfets

[@gravedigga71]

You should try a different power supply on the second one. Maybe it cuts out.

[@dogastus]

Seems a bit suspicious that those bottom two mosfets aren't getting as hot as the others. Could you put a 'scope on their gates to see if there is a difference in their drive waveforms?

[@Davic28]

In the case of the second ps5. I think that could be a psu problem as well. I hade it with my pc once that when I started a game my pc shut down because the power supply was damaged. When the comonents draw more power it could not handle it propery and shut down just like that ps5.

[@pyromaniacattack1784]

Try swapping out the PSU on the second one, seems like it's crashing when the power draw ramps up.

[@petersmithm9]

First one will buff out. Stick some masking type on and Robert is your uncle.

[@justinc9991]

You’ll need an oscilloscope to measure the frequency on each coil and see which one is different…. the frequency is generated by the mosfet controller (phase controller). So you can try and swap the phase controller. Regarding the 2 bottom mosfets that doesn’t look they are getting hot, they might be “used on demand” when the apu needs more power phase controller will activate those mosfets also. This is why you see them glowing from time to time. In full load, apu will ask for power and they will be activated by phase controller. Good luck!

[@JJ21lives4ever]

Joey, did you test the second console in a donor chassis? If not then I would try another power supply. They can test ok at no current but cut out under load.

[@garysweetland32]

Could the 2nd PS5 issue be the PSU giving up when warm?

[@benidino]

I have one PS4 pro kinda close to that second PS5 I can't play sometimes hours straight. Then sometimes after 10 minutes it goes black screen but keeps on. Until today I can't solve the mystery

[@gtheduke]

Did you try replacing the coils on those MOSFETS?

[@ghosthost92gaming73]

I reckon you should try and fix the second one on a stream. Would be nice to play around with it

[@madhampster]

Change the power supply on the second one.

[@eathenalexander2836]

The 1st ps5 I genuinely think it was probably an internal short , maybe a bad board from factory.

[@Playgamesbad]

Hi joey, been watching for a while, love the vids, got a technical question for you, sorry if it's been asked before but I've always wondered, when changing ports etc, why do you add solder, remove all the solder then add more? I understand the part around leaded Vs non leaded, but if it's already melted, why can't you just put another port on? Thanks!

[@nelsonfigueroa3198]

Joey . . . Its the power supply. Swap the one from the first dead one to this one.

[@neubivashka.]

Oh my, that burn 😢

[@TheSkaldenmettrunk]

You can't always win. But it made a good video and the nexf one will be another win.

[@GavinColbourne]

The sooty look on the 2nd PS5 looks to me as smoke damage around the fan

[@Can3Fix]

The second PS5 is weird, I would test it under a 10A load or try another one PSU.

[@Kolor-kode]

PC/Server PSU's can test fine but shit the bed under load. Possibly that?

[@intoxicode]

Before trying to diagnose motherboard issues with power always replace the power supply first..

[@mirayanomi]

The second PS5 is either a powersupply issue or the driver IC for the fets

[@ronny332]

I like the smell of exploded components, no joke.

[@TheSpotify95]

Holy smokes, as soon as I saw the burnt out piece on the first PS5 I knew it was game over and -£150.

[@garethcozens1672]

Has anyone ever come across a PS5 that wouldn’t start because it’s too cold? Blasting with a hair dryer for a few minutes works a treat but otherwise nothing.

[@nielsen145]

sounds like a psu problem in my eyesm i did had a similar problem on pc, with a psu i had, as soon you put a load on it, it shut off, otherwise it worked fine the psu

[@terouotila1425]

Average profit over all episodes is on the plus side by £5,84 after all. To get to the thousand pounds this series aims for, it should take only 172 episodes 😀

[@mart43]

Have you checked with the oscilloscope?

[@MasterAlexS]

I think you should really try another Power Supply for the second PS5 since some of them can work when using low power and shut off unde stress I expect that Power Supply is near the end of its life

[@dadachoski5946]

Change the PSU

[@HessenBub87]

If every try to fix is a win, then this series would be ending too soon... 🙃

[@znausea]

Why not try another power supply Joey? I realise the power's there but it could still be intermittent

[@grahamwise5719]

what drives the mosfets? that might be the cause

[@ovidiu7290]

Looks like power is not enough for core. Ram seams good in my opinion no artefacts etc

[@DavidTablet-nt8qy]

Good try nothing ventured nothing gained hang in there!!!!🎉🎉🎉🎉

[@DavidMadeira29]

Do you really need a faulty channel if you're not going touring with those safe bridges issues?! I don't know. Namastè.

[@mindmending]

Try a known good PSU on number 2

[@davc6879]

Lol the first ps5, they opened it and said nope

[@PeterFalconII]

Why don't you have some fun and take a board the same that is not burnt and swap the full system over to a new board. Don't replace the components replace the board... It would make for a great video...

[@Canterhood]

❤

[@Lamadawid]

Try repair that ps5 just for getting skill :)

[@Ladiesman2I77]

Why don’t you , instead of taking off £150 why don’t you add up the total value of the console for parts and replacements , then deduct …. Just makes these videos pointless …

[@robhood-c2o]
