Vince use gas for lighters to find short - you froze board with liquid gas, then you can spot short in seconds. Check out my comment.

[@rock.doctor]

you should never get down on yourself for not being able to fix these...even Apple doesn't fix them, they just replace the board. They are so complicated they are disposable... You tried and you learned a lot and that in itself is a win in my book. New knowledge will always be a win.

[@megatronskneecap]

Apple actually used to label each and every little compontent they put on the logic board with a neat little bit of white text next to it but of course, that made the boards to easy to repair so they had to scrap that!!

[@nicolasbrenta357]

Man, from 45:10 trough to the end of the video is where i can truly see the amount of dedication you put into every repair you upload, i would've give up after the first voltage injection. Truly amazing work!

[@Denise_in_progress]

Vince always check the 19 v power rail ,check the mosfets at the beginning where you put in the power. If all okay then check the 5v power rail, if okay then check if the bios chip has 3v. I highly recommend a heat camera. Good luck

[@BarrySmallwood]

even when you don't fix things your vids are still very entertaining

[@unimportant5122]

@My Mate VINCE The reason nothing is heating up on the board is that it's a very low resistance short. The better the short (lower resistance) the less it will heat up. Dissipated power = I² * R, so the closer resistance (R) goes to 0 the less power is dissipated, even if current (I) is high. (A 0 ohm superconductor would not heat up at all, at any current). You'd need a thermal camera to see something that's heating up only a little and sometimes the short is so low resistance it won't heat up at all... The reason your crocodile clip heats up is because it's making a poor connection. The slightest bit of poor connection will result in a higher resistance in the clip connection then the short itself. For such tests it's best to solder all connections to ensure proper connections.

[@dogastus]

A technique I've used to see what is warming up is to give the board a good dosing of freezer spray so that it gets frosted up. You can then easily see what is warming up when you apply power and see what defrosts soonest. The other tool I've used is the Polar Toneohm. This is a milliohmeter and is very good at tracing shorts. As the name suggests, it puts out a variable frequency tone, so you can quickly probe lots of points and trace the highest pitch point which would be the lowest resistance.

[@mikediying8729]

Thanks for this! Its great that you showed the instance when things dont end up all hunky dory. Appreciate the effort and patience you put in. All the best for the next one!

Look for cracks in the tantalum capacitors, a hard short is often due to a blown tantalum.

[@AlexsAnimals]

From reading some comments and doing some research of my own, I think it is possible that with the failure of the power management chip, the SSD may have also died. I wonder if it is possible to find replacement ssd chips and replace those? Great attempt Vince, I really appreciate the attempt!!

U9500 is shorted sending 3.3V to l9520 , L9521, I would replace U9500 and reball U7800, U9500 has internal mosfets , Reballing that chip would not be an easy job, great video, The only worry is if the ssd survived 👍👍👍

[@Mymatevince]

Thanks AR, I knew you would have the answers. So...I looked on eBay at a similar 820-01041 board and noticed that it didn't have the U9500 or the SSD that it fed. So I thought on my one it might work without the U9500 and use the other SSD's. I removed the U9500 and 5V jumped to 20V after a few seconds and then started to climb on the Amps until it was around 1.5V at 20v. Nothing came on the screen, and then the U7800 got hot and it went back to 0.02A 😥. Now it is behaving the same as before but strangely some USB-C ports give 5V and some 20V!!!!! I will wait until a new U7800 arrives and try again. Do you think it could work without that U9500 and the SSD it feeds? Cheers for the help as always 👍👍😎

[@blasphemer71]

Hey Vince, it looks like you could use a thermal camera. I have one that is broken and I've been quoted £220 + £30 shipping for repair. I'm not prepared to spend that on it, so I was wondering if you would like it, for a video, and if you can repair it, it might help you on your next macbook/laptop repair. I've had a look and I can't find your P.O. box reference anywhere. I would send it if I could find the details. The camera is a Flir C2, i have opened it up and had a look, and found that the power control IC has a short, or it gets very hot when the battery is connected. I removed a couple of smd capacitors to see if that removed the short to no avail, but I'll pop them back on if you want it. As far as I can tell, the screen and cameras are ok, but obviously I've never got it to power up. Let me know, cheers. Dave.

[@solveit1304]

Vince to find a short without thermal camera there is a better way - just use gas for lighters. You grab plastic end and spray the whole board with liquid gas. It will froze everything so you can spot short in seconds. From my experience this liquid gas for lighters in not conductive, just leave some residue, easy to clean with IPA. Funny story how I came up with that idea - when I rent a flat, landlord close gas stove thermostat controller behind steel box with lock. About 16°C inside room :( But there was a vent hole in that box, so I was injecting ligher gas inside it to cheat thermal sensor on PCB. Gas stove kick in immediately after injection, heating like there is no tommorow :)

[@unitedfools3493]

Can't you just do this with IPA though ...

[@solveit1304]

@@unitedfools3493 you could, but it's inefficient. IPA is transparent, hard to spot. Lighter gas leave white frost on components, so you could cover whole board with it, then watch for unfreeze spot

[@csgultekin]

there is also a thing called freeze spray for electronics, that is less flammable.

[@solveit1304]

@@csgultekin yeah, you're right - little fire hazard. This is full "ghetto" option, freezing spray is like a standard option, thermal camera is pro option.

Accidental touching of ground with the positive lead, with lighter gas, can lead to more to fix, if not become impossible to do so.

[@dodgydruid]

What the electronics world needs is a dedicated electronics version of a bridge megger which measures a short in normal sized wiring and you can "zoom" in on the short by interpreting the reading on your megger, the stronger the reading the closer you are until you get almost a full meter indicating your insulation side of the circuit is bang on the short pretty much but means you can with some confidence cut in a new section of wire. I know the telephone engineers used 'em as did the army and navy etc the navy ones could be 500v output because of the long distances between junctions. My one is I believe an ex GPO Everard unit of 120v which came with a 100ft of line for the insulation circuit and a 10ft line so guessing this was likely for homes or flats sort of application thinking on the average manhole to house distance back then in the days before green cabinets.

[@rickydeldo8596]

Hi Vince, its the power management chip, the american dude has made a full video about it, because he couldn't source it from anywhere. Its custom made from Renissance chip manufacturer.

[@digihorse6730]

[@jasonbucy]

It might be expensive, but you should get a infrared camera like a flir or something. They can connect to your phone and you might see abnormalities inside the board or slight variations in temp that you wouldn’t normally detect. 🤔🤔

[@christianramakers7166]

Great video! Always enjoy watching your videos! I’m not an expert at all, but I was wondering.. If the SSD is the fault, would desoldering the SSD not give you a picture on the screen? It would prove the fault and you might be able to run macOS from an external harddrive.

[@philoso377]

Multimeter, 1.5 V and 9 Amp power are sufficient to locate short on a circuit. A small size needle compass will tell us roughly the direction of current flow.

If it’s water damaged alcohol and a toothbrush are your friend. Soak the motherboard (only) in white spirits for 10 minutes then take it out and brush all chip contacts and anything metal with a toothbrush. Then sit to dry for a couple of hours before reconnecting. Not all water damage is visible. I used to buy broken MacBooks from eBay all the time and managed to fix every single one of them. This technique worked on 99% of them without removing any chips

I've never owned a MacBook, as I'm not an Apple fanboy. But a lot of the time, if owners abuse their devices, then they will not last very long. And £350 for a non working laptop is ridiculous. However, I own a Dell inspiron 1545, and I bought it new around 2007-2008. It came pre installed with Windows XP Home, 128Gb of storage, and 4Gb of memory, and it still works perfectly. I had increased the memory to 8Gb, installed an SSD where the DVD RW drive used to live, and had upgraded to Windows 7, and later, Windows 10, which it is still running. It is still running with the Intel Celeron DUAL core CPU, and the original HDD, which is now used only for storing files. Windows is run off of the SSD for faster boot speeds etc. The display, although not as bright as modern displays, still works with no issue with 720p resolution. And I also have the original battery, which still holds a charge after 15 years of use, although it only gives about 30-35 minutes runtime. But apart from a couple of new keyboards over the years, the extra memory, and SSD, everything else is original, and it still looks like a tidy machine, that still works. I was so impressed with the length of time it lasted, that I bought a brand new Dell inspiron 7570 in 2020. And I use both computers regularly. I would definitely recommend Dell, based on my own experience.

[@IlBiggo]

Heh, this just shows how personal experience has no value. I've kept the same iMac since 2011, taking it from 4 to 16 GB of RAM, and from a mechanical HD to a 2TB SSD - I had even upgraded the graphics board for a while just to play a particular game, and all this on a compact "all-in-one" machine. The MB I'm writing from now is of the same vintage and has been similarly upgraded; I might have had to get a new battery, but it could have been on the previous macbook, I'm not sure about this. It's not been abused but it actually fell a few times with no consequences. In the meantime I've tossed a couple PC notebooks (HP, they're trash) and 4 PCs - one very good HP (a lightning burnt some chips) and three Dells (all stopped working with no apparent reason, I revived the last one but it's crawling at snail speed and well, that's all the PC I need). I've come to the conclusion that Dells are useless wrecks. Definitely a different experience from yours. I know a number of people who occasionally have problems with their computer (being the local hobbyist fixer), and I don't see one brand/kind being more prone to faults than another. Mac owners get furious at their computers just like PC owners. If anything, PC people are more likely to just buy another relatively cheap computer and start from fresh; Mac people usually spent a lot on their stuff and want to keep it until it rots. But it's probably only true for the ones I know, as the internet seems to tell tales of "apple fanboys" running to the Store every time a new model is out, and "PC wizards" running last year's games on 20 year old machines :D

[@hermanmunster3358]

@@IlBiggo Well I guess it all depends how you treat your devices, as to how durable they are. I agree about HP laptops though, as I had the unfortunate opportunity to own one once. They are absolute trash. But Macbooks are just way too over priced for what they are, and what they can do.

wOw,, Very Gallant try Captain @! These are all I use, and now on my 4th MBP - being they are the only ones with Firewire option for external drives. My older MBP by mistake missed connection to USP battery back up,, and was unfortunately hit by lightning, waking to explosion from transformer on the pole in neighbors backyard,, and in pouring rain left both our yards on fire from the coolant oil from inside. Apple had a heck of a time getting him repaired, and had to go back again for a component they forgot to replace. Noticed you mention it's not a water damaged event,, but maybe it's a severe line voltage spike that took it out, causing the mystery. Strangely enough - this new MBP not even a week old went under water, when Son's mother borrowed it to take a bath,, and two seconds later walking in,, splash,, down it went while playing a movie. I totally got it to recover by the next day,, and still using it at this moment. One thing not done - sinking deep into Rice,, what a mental case scene that is for any electronic device. Basically set it next to the Titanic,, and let the corrosion process begin with live power not able to disconnect. I can explain fool proof method another time - or read about it on Fixit. Cheers

[@KB1UIF]

Vince, your VC04 will not provide the current required to allow the high current into the board and power itself as the battery has next to no charge. So every time you attempt to use it, it powers off. The heat you detect in the croc clip can be generated in the wire that you are using because the wire gauge is too small, so the resistance of the wire and that current is causing it to heat up. Poor contact resistance will also cause heat. If you want to inject high currents into anything you will need leads that can easily handle those currents. The answer is BIGGER gauge wire or good leads !!!! Most of the cheap Chinese ready made leads on the internet will not handle high current, get better gauge leads and better probe leads too. Crappy leads will measure voltage without any issue because the current required by the meter measuring the voltage is very small. You will normally see the issue when measuring low resistance or high current !!

Instead of frying the PCB with the old heat-feel-test you could inspect the caps under a microscope to see if there are any tiny cracks, why not desolder them all, and see if the short is gone, injecting voltage is only safe to do if you own a FLIR because of the lengthy voltage injection otherwise with IPA. or other methods like feeling for heat. All-in i'm fairly disappointing to see you working on a device if this Macbook was mine.

The thermal methode does not work with direct shorts. The voltage at the short will be so low that even with 10 amps there will not be any considerable wattage which would heat that point. 10mV times 10 amps are only 100mW - which will be easily consumed by the surrounding pcb. Let me say you where lucky that there was no trace destroyed after your test because 10 watts went into them - may be the most of it was in the leads. ;-)

good job mate.

In order to limit your tactile efforts, maybe you should use a thermal camera instead...flir sensor...just a thought...✌️
