I tried something a little bit different in todays video. A few people have been asking, so lets see how we get on :)

What I like about Joey is that he's actually showing how hard it is to fix things.
After over 20 years away from electronics repairs (tv/videos) these old apple laptops have been my entry back. So having never used a thermal cam, hot air station/flux until I saw your videos I actually used the thermal fault finding process I learnt off your channel to find a chip at around 50 celcius, and a s/c cap by it. Swapped the cap out under my new microscope without acually flicking the component off never to be seen again and seconds later the chip was around 30c and the logic board was repaired. Chuffed to bits to say the least.
You likely dont have a short just low resistance line to the cpu. However that chip is the real time clock, rtc. That is important to operation and is very common area for corrosion. I would say get a replacement chip.
Nice to see different electronics, Joey. Keep'em coming 👊
I would love to see you fix some old school consoles!
Good to see you branching out to other, non-console devices! 👍👍
Probably unrelated, but at 4:21 there's a small cap at the left of the screen that seems a bit burnt?
Oh yeah! You have fantastic eyes!
And the chip directly under it looks like it might be missing two pads at the top. D688 appears to be lcd driver chip?
I came here looking to see if anyone else saw that. Now I'm genuinely curious if that burn mark is the issue
Hey joey. In the video around 4:08 if you pause and look to the left you can see two components around a burn spot
I think this was a very worthy change! MacBook repair will be hard in the beginning of course as you build up some supplies and understanding of the various rails, but I think you'll get a lot out of it -- especially since you said it's something you'd like to know more about.

Joey Does Tech:
Great video as usual, you just need to update the link in the description to book a repair! (The "/pages/" part needs removing)
Thankyou :) just updated!
I build and repair custom gaming PCs for a living and do some console refurbishing on the side. I'd steer clear of Apple stuff. They can be a pain in the ass.
It’s always good to see something different. The process of fault finding is the same, but it’s a lot harder to find a good starting point.
The microscope and thermal camera approach appears to be excellent tools.
i picked one up from the dump once that wouldnt turn on. opened it up and the battery had been unplugged, still using it.
Good to see you branching out, Paul Daniels is the the magic guy for help
"Paul Daniels is the the magic guy" - not a lot!
You should get an old broken Xbox 360 phat to fix mod it and sell it, preferably a jasper 12.1A they where made from 2008-2010 and are the most reliable as they fixed the gpu. However if you’re looking for one that you wanna fix, look for ones with stuck dvd trays, or “open tray” errors or ones with rrod (Red Ring Of Death) if you buy a rrod console buy a jasper rrod as it’s less likely to be something major like the gpu, just make sure you try and find one that hasn’t been tampered with, the warranty sticker is under behind the faceplate. Rgh 3 is easy to do and only requires 2 wires, a diode and 22k resistor. I believe you can also use a raspberry pi pico to read and write to the nand. Would definitely make for an interesting video, also I do apologize for the very long comment.
For this board - is over. But please never connect power to the board without any IC. If this chip somehow drives any PWM on the mosfet and you remove it - that means that without control the main power rail (~20V) will go to the load (CPU, hub and many other really expensive chips)
Hey Joey! Just a quick one, if you head to 4:00 into the video, it looks like there is a burnt out cap just above the D68B chip. Could be wrong, but may be of some help!
I picked up a MacBook Air a while ago and have been left in the exact same position. I can get a charging light, but I do not get any power. along with the MacBook I did get there charger and it was aftermarket. I wonder if the non-apple charger is the reason why I can charge the battery but I can’t turn the MacBook on.
I honestly think that the model you got is the exact same one I have. This could be a common issue with this particular MacBook. Hopefully you revisit after some research. We might have the exact same issue.
9:29 it is not one of the main power rails ... it's THE main power rail ... i believe it's called pp bus g3 hot ... and it's around 8.3v
Hey Joey just to the left of the first chip you took off there is a cap with one end that looks corroded. might be worth cleaning it up maybe.
What a pleasant surprise for an already disappointing Tuesday. Appreciate the upload.
My immediate reaction before even watching this, is are you in contact with Adamant IT ?
Poor sally.
Good idea for content !
waiting for more !
we back at it againnnnn
Rossmann will be proud :)
Finally something different
what's the software you are using to see the board Great video
Joey, do some bean to cup coffee machines. Dead easy.
Yo I saw on TikTok that those problems turn on turn off from Xbox series can be the HD cable, thought of you
Love this series!
Really enjoying your vids I'm into fixing pcs laptops I got a tablet it didn't display so I got replacement and was told to keep it for spares I I opened it up and found a ribbon cable wasent attached it was the screen and it worked thanx to your vids I opened it 😊 the clip
I'm no expert, but did you try the thermal cam again after you've removed that chip?
Given any thought to trying to fix other appliances and such for repair?
Always fun to watch. A bit sad when something is irreparable or not worth the time, but at least the donor supply is happy.
Joey I have 2 mac books you can have to practice on. Both with power issues.
:O that would be amazing. Could you send me an email please bud? joeydoestech@hotmail.com
A JDT video on a weekday? Must be my lucky day
Ya everything and anything you think you can afford to try and fix.
Stay away from the consoles for a while especially this time of the year lots of scammers selling broken consoles that can't be fixed just selling items to get yours & everyone else's cash
Would the laptop power up with no drive?
Like your are also working on laptops and other stuff. Don’t think it does make sense to work only on consoles
Electronics is more than just a PS4 or so
Hope you stick to video game systems. That is why I love your channel.
Wouldn't the CPU show low impedance anyway? Replacing the chip has surely gotta be worth a punt.
Cut the trace to the cpu and test again
If same repair trace
Oooo computers!, yes this is different
another ouch and better luck next time
Shit, i really was hoping that corrosion on that chip was the problem but no. Really hope next video wiĺl be a fix. Very nice to see you try something out of your comfortzone 👍🏻
Thats Not An M.2 Thats A Custom Macbook SSD
I hope there's profit somewhere down the line.
CPU FAILURE, COMMON,
And as always, I hope you've learnt something.
Nice
never try a laptop board without chip that you dont know what is doing! if it is for some power rail you may send 19 vold in every chip on this rail without the chip! i learn this the hard way by destroying a laptop motherboard! if it is for example the audio chip no problem the lan no problem but if its for some power lane its game over! sorry for my english! lets hope you start getting better luck with the next repair!
Thankyou for the advice :)
😊
That sounds extremely unlikely if you remove something power related it means you break the circuit how does 20v flow through? Unless you have directly connected it yourself it won't do any of what you said.
@@mirayanomi then how do you explain the 10 ohm short that got to 1ohm after testing it without the chip? so i will ask the guy that told me that, to explain me why it is happening and i will post agian!
get something you can actually fix. like lenovo or acer or something. not a stupid mac.
Smell like burned CPU, keep for spares and buy similar one, make one out of two.
It’s all going so wrong! Hopefully this episode is positive! Have you tried just pretending to fix things then tuning on a working console just for the TH-cam? /s
Joey is too honest to do that.
Hellooo
I really like your approach to things and your videos. But there is one detail I find really disgusting. Is there a chance that you change or wash your gloves from time to time? To my knowledge there is no other youtuber in the repair community who is working with such dirty gloves. Don’t get me wrong. It’s nothing personal this just looks somewhat unappealing. peace ✌🏻 👍🏻
