@TheSkaldenmettrunk 8 месяцев назад

The same to you.

@FG-Supercharged 8 месяцев назад

Typically a "small" value (and typically size) capacitor is used for filtering high-frequency noise (such as CPU and memory clocks, etc.). "Large" value (and size) capacitors are used for filtering low-frequency noise (power supply hum such 50/60hz, clicks, etc.).

@lumbo101 7 месяцев назад

Yes, it’s to do with smaller capacitors having a lower self-resonant frequency.

@spambot7110 7 месяцев назад

or, from a physical perspective, lower ESR/ESL

@topgazza 8 месяцев назад

What a superbly explained piece of fault finding. Excellent stuff

@abbyson2834 8 месяцев назад

Good video ;) But you should look more into the tasks of the different coils on the motherboard. The question should have occurred to you much earlier as to why the VRAM gets warm when you apply voltage to the 12V main supply and have a short circuit there. Because then you would have noticed earlier that the APU has been dead for a long time because somehow the power supply to this rail has died in a way where more than the 1.35V necessary for GDDR6 made it onto the rail, which damaged the VRAM and the memory controller in the APU.

@FR4M3Sharma 8 месяцев назад

How we not have companies releasing schematics for these devices when they're made in millions of quantities and use so much energy and materials to manufacture only to end up in a landfill is insane amount of waste that no one talks about.

@sneezyferret6482 8 месяцев назад

Yes it would make life easier for the right to repair movement. All schematics should be available. But they will complain that it's their IP. I had an issue with a commercial espresso machine that was overheating. Tracked it down to something electronic, vendor were no real help, just told me to buy another circuitboard and then ghosted me. But they cost nearly $2000 (!!!) with shippping...so NOPE. Broke out my multimeter and went round the board instead looking for faults. Took me a bit of effort and help from an electronics forum, but I found a couple of faulty triacs, which I replaced for about $50 including shipping.

@toxicityofthecity226 8 месяцев назад

Because it is bad for the business. They are hiding their IP? Thats bullshit all they about is money and sales. Gaming entertainment shouldnt be handled by business men. They are tainting the gaming world.

@markellii3093 8 месяцев назад

I think it would be fair if it worked somewhat like patents. After a certain time, dependant on the device in question, the schematic gets released to the public. (5-15 years sounds fair)

@Cire3PC 8 месяцев назад

The lobbyist wouldn’t allow it. Follow the $

@michaelgleason4791 8 месяцев назад

Yeah except for hundreds if not thousands of successful RU-vid channels and their millions of commentors, no one talks about it. Not to mention start-ups that are explicitly making products with repair in mind (Steam Deck, a few laptops at this point, several other big projects). If only one person would talk about this issue.

@slickrx6908 7 месяцев назад

Wow.... Been watching the bigger repair channels for years but none compare to the amount of helpful verbal explanation Joey provides

@adagioleopard6415 7 месяцев назад

The larger caps provide bulk storage for large current draw. The smaller ones can act quicker. So on a PSU we allways have some large caps and some small caps.

@robingrosset6941 8 месяцев назад

Loving this series Joey! My guess is the little cap next to the big caps is probably related to voltage supply noise suppression. The different value caps charge and discharge at different rates so they suppress different frequencies of noise. The combination of large and small capacitors can help smooth out both slow and fast voltage fluctuations..

@cattflap1447 8 месяцев назад

You need multiple caps to get filtering over a wider range of frequencies, ie a 10n with a 100n etc. The different sizes are due to larger values being a larger size.

@willkra 8 месяцев назад

@afj2276 8 месяцев назад

there should be a rule with Ebay listings where if an item that is not working has been opened previously then it should be declared and the value of the item marked down accordingly.

@allnutty 8 месяцев назад

It said in the screenshot of the ebay post "looks to have been opened previously" ?

@aserta Месяц назад

10:37 think of it like weights on old school balances. You have large ones, and you get 4 kilos, and then you need to trim for a few grams, so you use one 1 gram weight and one 3 gram weight. Same there. You filter a system for noise, you have machinery that either calculates or "sniffs" the noise in the board, and it tells you: "put this part and this part on that board". I guess a more modern analogue are automated wheel balancing machines. They'll spit out the exact weights, exactly where they need to go, down to even putting a laser to align the premade weights to the rim.

@wallygrandpa 8 месяцев назад

can we conclude that repairing and flipping isn't really lucrative. But it does give you some really good experience. Of course, everything could change.

@chris-pike 8 месяцев назад

Good to see more of your Profit or Loss there Joey Happy New Year Mate 👍

@nayt33z 6 месяцев назад

different value caps filter out different frequencies. That would typically be why you would see different value caps in parallel. to filter out noise from switching components like mosfets, transistors, etc. smaller value caps filter out higher frequencies and larger value caps filter out lower frequencies.

@Google_Is_Evil 8 месяцев назад

The tiny capacitor is to filter out the high frequency switching noise, while the big ones are to stabilize the actual voltage. The big ones will be too much of a resistance to the high frequency noise so there is a small cap parallel for just that.

@DoctorCalabria 7 месяцев назад

When you say that the fuse is shorted, doesn’t that mean it is working? I thought if it was open circuit, that means it is blown. Sorry if this is just semantics or am I missing something else? Thanks for any clarification. I’m probably just misunderstanding since nobody else in the comments mentioned this. Great video. Thanks 🙏

@chrisgr00ver 8 месяцев назад

Hey Joey, love the content. Was wondering how you’d recommend learning to diagnose electronics? I always see people checking for shorts to ground but am not quite sure how you determine what to check and know that it’s not supposed to be to ground. Any suggestions? Appreciate it!

In Brazil we can't refuse returns because of an outdated law. That is why I don't sell anything on ebay.

@sneezyferret6482 8 месяцев назад

Can you reball and/orswap out that APU from the donor board?

@slickrx6908 7 месяцев назад

So looks like the previous guy could have injected too much voltage and recked the APU on an otherwise fixable board.

Are you sure its not a multi layered PCB and only a double sided? Those vias could go into an internal layer that is routed elsewhere.

@lemagreengreen 8 месяцев назад

"Unknown history" on For Parts/Not Working eBay stuff basically means a tech has already isolated the problem as not viable for repair and the store have offered the customer some token amount for the dead item which they then double/triple by selling on eBay especially if it's something they will have multiple donors of already like popular things like games consoles, laptops etc. It's hard to pin down who is a legit. private seller with something broken that is actually repairable, anyone selling For Parts stuff on eBay knows the smart thing to do is sell from lots of private accounts rather than as a store to avoid being identified easily.

@drcyb3r 8 месяцев назад

If you want to make (fast) money on repairs, do easy things. It's not that interesting but more profitable. I fixed a few Nintendo Switches with a broken screen and made some good money with that. Or try fixing slightly older stuff.

@leewright6101 8 месяцев назад

the sisue you got joey lad is ,, buying any ps5 or xbox is a huge risk nowadays, people wont sell a working on easy fix ps5 or xbox, 9/10 times they been sent to someone else who may og made it worse with no idea, shoddy workmanship, or even engineer found it and deeemed it knackered only to pass it off to some other engineer looks like on this ocasion its been passed off too you,. shame as i feel u i been a electronics engineer over 40 years, and love it as a hoby and to make money.. been ripped off more times, scammed , and well even fixed tvs to repair backlight and ended up a few times dammaging screens left with sod all it happens, all the time its a good game to be in, but i think its time to get rid of all the consoles you buy as there a nightmare, personal experiances, maybe some laptops. other electronics, maybe,, but consoles too much hastle., at least with other electronics, you can mostly get the parts, bit expensive buyin faulty consoles if apu is shagged then,, utter waste of money,,, i just wanna shake u lol,,, say joey for god sake, man, get something other than consoles.

@PhN1800 8 месяцев назад

Shouldnt the 12 V line be completely separate from any logic/digital IC and only go to DC/DC converters? I would think the apu and ram only runs on 3 and/or 1 V.

@fabian11235 8 месяцев назад

Yeah there should be some silicon between the 12V rail and those and generally if the 12V rail is shorted to the ram its gone to the apu too. The ram has lots of data lines running to the apu.

@TheSpotify95 8 месяцев назад

Oops, as soon as I saw that the console had been opened/repaired by someone else, I had my doubts. I was thinking APU/CPU all along, and I was right, so it's minus!!! The question is... why do all these consoles you look at (Switch, PS5, Xbox, etc) all suddenly seem to have failing APU/CPU?

@LiamCrayden 8 месяцев назад

PS5s are notorious for it (probably linked to having them stood vertically). Switches not so much, but NVIDIA have had chip problems like this going back almost 2 decades so it's not surprising. I think the bigger issue is with buying on eBay in general - 75% of faulty items have already been looked at and a failed repair attempted by at least several people before, but nobody wants to admit to that on the listing 🙈

@adamarzo559 8 месяцев назад

I'm still trying to learn all of this from watching these videos, so my apologies if I'm about to say something horribly wrong here but I don't think it's the CPU that is directly failing. From what I've seen with laptop repairs is that a mosfet will often fail, and then that will allow the short to bleed into the CPU and ultimately kill it. Again, still new to all of this but surely these companies can put diodes or something to protect the cpu.....?

Let's be honest here. This series and your recent live streams arent exactly a good advert if you want people to send you things to repair. Not good at all.

@JoeyDoesTech 8 месяцев назад

It's hard to argue with this to be honest, I completely understand how it would come across. What I would say and will probably mention on future videos, is that repairing consoles on eBay is not a good way to make profit, but is a great way to learn. I'd comfortably say I would have somewhere in the region of a 90%+ success rate fixing customers consoles that haven't been opened before. HDMI ports even with ripped traces are 100%. On eBay almost every single console bought, has been opened and attempted repair, then just put back into the market as faulty with no prior repair information making it a very risky gamble. I 100000% see why this may put people off trusting me to repair consoles, but I actually value honesty over everything which is exactly what this series is about. Thanks for the comment 😊

@nheather 8 месяцев назад

To be fair, the seller declared that it had been opened before and that the history was unknown. Assuming the seller is being honest, and it sounds like they are, my immediate thought is that they had bought it wondering whether they could do the repair. And watching the rest of the video it feels like the seller has some electronics experience but has possibly not done much (or any) hot air soldering before. I say that as someone with a degree in electronics, a dab hand with a traditional soldering iron but having never worked with SMDs or hot air soldering before - I know the theory but I’m sure if I tried it I would make a mess until I got more experienced. To me me, this is what this board looks like - someone with a little expertise and experience who decided to have a go, made a bit of a mess, decided that it was beyond them and sold it on to cut their losses.

@95Comics 8 месяцев назад

Why couldn’t you swap the apu from the donor? Great video im definitely a new fan of yours!

@JoeyDoesTech 8 месяцев назад
