Riddle - 2 girls were born on the same day/month/year to the same mother...but yet they are NOT twins. How come?
Must be part of triplets then
Genetic engineering. They were born to a sheep.
One was born at 00:00 and the other one was born 23 hours and 59 minutes later.
Or they were born to different fathers.
Turn it into a halftop
I sorta cheated and Google'd the answer, since my guess of "leap year" was wrong, but here it is: Because the woman gave birth to more than two babies in one pregnancy.
FYI for future attempts: Under the apple menu, select "about this Mac" In the window that comes up, click on System Report. That'll give you a view into the hardware the OS is aware of. So for example you might see that the internal display isn't showing up in the device tree.
Hey Vince, When you were measuring the resistors next to the Backlight conector you were getting a short circuit on one side, Resistor don't short which means that there is a short on the rail. check the corespondent components associate with that rail. Maybe a shorted capacitor.
It is likely a open resistor, I had same issue and measure a short pretty much even though wasn't any short and capacitors tested fine out of circuit, but rail only measure 2 volts. It protection when that sense resistor goes open. I almost gave up and actually assume display was bad, replaced resistor and display and keyboard backlight came back to life. I fix another but had bad capacitors a couple giveaway if they crack, or darker then others and mosfets were to CPU were also bad and charging commucation bus IC but it had more liquid damage. Yes good idea to check capacitors in area as well.
Yes fan will go full speed and display won't display anything, or be detected. It has protection sense circuit on these, which I didn't even know at the time and almost assume was screwed. I actually replaced driver which did nothing and almost bought a display, which would have been a waste of money as they are expensive. I glad I decided to look at schematic and give it another go at it.
@@thetechgenie7374 i agree with this
Revisit video incoming 😃
Thanks for the help, on the left hand side resistor (R8502) the left pad is a ground and the right side goes straight under the CPU. The right hand resistor (R8503) which from memory is the one causing the short also goes straight under the CPU on the left side pad, BUT the right side pad does go to other components so I suppose there is a chance one of the other components is shorting it down to ground...Hmmmmm I will have to look into this again. Thank you!!! 👍👍👍
@@Mymatevince Definitely don't give up. Remember the Macbook Air? :D
Likely a open resistor by backlight driver usually the r8440 1m for sense line goes bad or blown driver. It actually cut out whole display off not just backlight, It is surprisingly a common issue come across on these when water damage. I almost assume display was bad till I only saw only 2v coming out of driver and found almost short across resistor which turns out wasn't shorted but causing protection to kick in which drop the rail down for some reason, their wasn't any shorted components, capacitors and driver was fine surprisingly, replaced opened resistor clean corrosion off board and fixed it, display came back to life and was using it for a year till I sold it to a coworker and got myself a 16 inch M1 You are luckly it didn’t take out mosfets which is also common with these. My lovely U2 Cooper a bird knock a cup of coffee on backside which is what killed it and charging IC that communicate on the bus.
Hopefully display itself is still good likely is as you tried other one and didn’t work.Your right the flex cable break on these is another issue. Even then a good price as board doesn’t show much damage and can likely easily be repaired.
I wonder if the backlight chip does screen and keyboard at the same time. I find it very weird both stopped working. Also you need a really bright light for backlight problems. I had to use a really strong light after lesser ones before i could see any image.
40V right next to data line often exposed to spill damage. some call it a design flaw, some call it marketing genius.
You are my hero with these videos. Keep it going !
Great video vince, really enjoyed watching this one. 👍
Hey Vince, when you hear the fans kicking in full blast it's always a sensor issue, most likely a resistor somewhere needs replacing. They don't short out, their value will just increase causing sense lines to report back incorrect readings hence the fans running at 100%! You have the boardview and the schematics, check all the resistors around the area where you noticed liquid damage.
I guess you can use MacFans control or similar, then just choose a working sensor. I did this after swapping some disks with FAR cheaper non-apple SSDs lacking the orginal temp sensors. I picked "average core", set a conservative number for the fans to really spin up. Monitored fan behaviour and temperatures during some hard CPU and graphic card work, was satisfied that temp never creeped above 80-90C even during full load on CPU (rendering, export of GIGANTIC pdf-files, like a 40 m2 banner with rastered images). This has been working without a hitch on several desktops and laptops for years.
Great video. I am not an Apple person but I wanted to start learning about them even though I won't be converting overall. I bought one working 13 inch mid-2012 macbook pro in order to see what Apples are about. I replaced the spinning drive with an ssd and replaced the DVD drive with a second hard drive and maxed out the ram to 16gb. It works just great and then I bought an aluminum stand for it to put behind an external monitor (27 inch) and it now runs with the lid closed with an external bluetooth keyboard and a usb mouse. It is like having a 27 inch imac. I liked it so much that I bought another and upgraded the same way. I just love the construction of these laptops. I actually like having the huge external display so you'd be well served on yours to give yourself some larger screen real estate and then to use the laptop with the lid closed. You've got yourself a true pleasure right there. So nice to see people take someone's cast off and to repurpose!
Great use of schematics to get the answer if not the fix. I always think it's a shame when you can't fix something but that is life. Some you win some you lose but for me I would be happy to have it working even on an external display. Great video as always Vince keep them coming.
👍👍👍
Just halfway through the video - LOVE that you can get the schematics of these machines - a massive help! I hope you get it sorted!
Cheers Kip 👍👍
I hope you making a part 2 or something like that! Good video. Thanks.
great work Vince!
Great to see a new video Vince, hope you're doing well, will we see an apple keyboard update for the others you bought? Take care buddy 👍
When you were voltage injecting the backlight circuit, I was pulling a face like Tommy out of snatch when he tries to test fire his gun out of the car window.🤣
Nice video Vince! Good job. 👍
I got that reference, and also pulled that face 😆
Such a shame on this one Vince, but hey at least you have a couple of spare screens. Maybe buy one with a smashed screen to replace the lcd with one of these to get your money's worth. Great video Macboominator 😁
Nice one Phil 👍👍👍
I am sorry when things don’t go your way Vince! I love that you keep trying.
Given what you said, I was wondering if there’s a way to route the external output to the lcd screen? Like a kind of retro RF to RGB mod?
Interesting video this one very enjoyable your fixes got me intrested in soldering again but not as good as you
I used to fix cash registers back when the dinosaurs roamed (70's and 80's). Lots of machines soaked in beer. You have to use water to clean as alcohol won't dissolve the sugar, which is the real culprit. More than once I washed a board in the bar sink and then walked down the street to a hairdresser to borrow a hair dryer to blow the water out and dry it off. That cured it more often than not.
Yeah I would totally wash the whole MB for that same reason. I've seen liquid damage repairs, and with thick liquids sometimes you have to remove chips to clean under them.
For anyone else that cleans up liquiddamage from sodas or other sugary drinks: you can (usually) wash boards with water as long as there isnt any power in it. Make sure there isnt power stored in caps too!! After that you can soak the board in IPA to dissolve the water instead of drying it with a blowdryer. That way the conducting minerals in the water dont remain on the board.
Thanks for another great video
Still love watching these Vince.
Love the upgrade in audio bro
Great video again👍
the laptop fixing series is my favorite series!
Damn, that listing was incredibly honest. Big respect for that seller. Honesty is the one thing that the eBay search bar can't help me find. Honesty and friends.
Nice video Vince. This is the second time I saw you ran into a CPU/GPU problem. I know it's normally not worth it, but how about reballing/replacing the CPU next time? I've seen some people do it even with home made equipment. That would be entertaining to watch :)
Real shame this one wasnt fixable. Really love watching your journey on each fix. I think you learned quite a bit from this one. Really bad design. Even if that connector had to be as made, you'd think they would then add some water protection from that particular area. Given the cost of these, how hard would it be to put a waterproof membrane under the whole keyboard with a liquid exit hole out the side of the case so a spill just went straight out?
good job mate.
love the macbook videos
Hi Vince, be careful with laptops and other devices resting on soft surfaces as these can easily block cooling air flow.
The carpet in this case may not be much of an issue but you should be aware of possible trouble caused by that.
Booom! New video is here, thanks Vince.
It’s a pity .it would be good if you could jumper the external video to the the screen and get the led driver working
But it would probably destroy it .
Good video Vince
The fan running at max is probably a temperature sensor in the display or ambient sensor not being plugged in, as well as the screen
Having been on eBay for many years I know that the rules sometimes suck, the reason why the seller had his negative/or otherwise feedback removed is because you kept the item.. That's all..
Thanks Colin 👍👍👍
But the seller kept the money...
Not even sure how ebay is still as big as it is these days with it just becoming a scammers paradise over the last few years.
eBay-I am twice bitten and forever shy. I don’t really fault eBay, but I got badly screwed on my last two transactions and have put the whole den of thieves in my rear-view mirror.
Hello. Sorry about my english. Have you try changing the magnetic switch that tells macbook that is open or close. I think Louis has video about it. Good luck, love your work.
Did you test the keyboard switch for turning the display off. I know it sounds unlikely but if you can ask a user with a working iPad to turn their unit of and on ti seevif keyboard light turns off because if it will you need to run back to test this for any changes you come across, if you jot down your finds to get a common test.
Great video - out of interest, did you get that display working in the end?
What was the fault with the a2179 after?, great videos!!
I work at a big box store in canada that does laptop repairs and the amount of beer, wine, other alcohol spills is unreal. Always smells awful
I could tell there was something up with the internal display when you hooked it to the TV. Macs default to desktop extension with the lid open (i.e. dock on internal display). With the lid closed (or if the internal display is not detected) the computer will use the external display as the primary display (with the dock).
what if it thinks that the lid is closed but its not 🤔🤔
@@SupertigerDev would the Touch Bar be on then?
@@Fade_Modded ah true
Vince, i noticed when you turned on the Mac at the end of the video, it had a few white dots on the new screen and I have been a viewer since the very first trying to fix video.I hope this comment helps you with fixing the MacBook. Also, maybe do a revisit😁
What model is that microscope. Want to buy one but not sure what kind. Thanks and it is a good video as always
Hi try to change the lvds board and the pvds cable they are not that expensive it worked on my 15inch touchbar got a super deal on it with simalr problem
The reason the backlight won't turn on even when you power the capacitors is because you need to turn the MOSFETs on.
My Mate VINCE you should buy a small medium size screen and take the top where the screen is off and turn the MacBook into a mini or ok sized desktop MacBook desktop iMac 🖥 machine. Use the keyboard as the hard drive by not having the screen connected and always having your hdmi cord connected to your desktop monitor tv screen rig.
This is a well known fault Vince with this connector, Louis Rossman covered it many times in his videos, such a stupid connector design and they’ve still not fixed it, seriously just put all the power pins together and all the data pins together and separate them with a thick plastic barrier.
Hi Vince can you not use the data line from the external display port run a jumper to the display port what goes to the screen
35:00 where you were pointing on the socket directly below that the capacitor looked crusty worth a shot
Shame the new screen didn't work Vince. I would have had to buy it as well just to know for sure.
So I notice the fan is tying to spin but stops, I had an issue with my apple AirPort Extreme where it would over heat because of the fan, turns out it needed grease or in my case, olive oil lol. After that it started spinning fine and didn’t have an issue anymore. Maybe the beer got to the fan and got the little spindle a bit stuck and the second fan notices that the other fan isn’t working so it’s spinning faster to try to maintain the coolness. try opening up the fan and put a little oil
1st class video to watch thank you take care kind regards from me kenneth
Did you check the traces of that display connector it might be broken in some places
Adamant IT would be a good youtube channel for you to watch he does quite a bit of macbook repairs
awe... Your daughter needs to wait for the next one I guess.
Great video as always =)
Hi Vince. Maybe Hall Sensor went back? Computer thinks that the lid is closed, so no backlight and image is provided.
That’s a shame that it isn’t working. I suppose replacing the CPU is an impossibility. Great video again though Vince. Cheers Graham
I got a A1989 (Complete laptop) with a mainboard damage, it was a small spill on the left USB C port, I cleaned it with alkohol, but some caps in that area are shorted, so I assume some ICs are gone. You interested buying it? If not, ill put it on ebay I guess. Other then that, love your videos!! Cheers from Austria.
Hi. Just interesting what gonna hapend if you use external display line going from cpu/gpu for internal display and disconnect damaged line?
Hey mate one think you can do is just to remove the screen and install fan control app and just just it like a pc but no mox just a nice keybaord and trackpad. Im not sure if thats something you would use / be into but you could also sell it as a "Headless" macbook
The CPU internal issue doesn't explain the lack of keyboard backlight though... I'm pretty sure there's something else. Send it to Louis Rossmann and have the CPU exchanged, still worth it if that's the only issue, but maybe it's something less expensive. Maybe there's some sense pin to enable the internal display... some sensor(s) are definitely bad in there as the fan is full on, that's a sure sign.
Metal and beer?? Sounds like a rock band! 😉
19:53 if you get that Retina screen working you will have a better view of that laptop because that screen is very nice
Can this be just sensor for closed lid if keyboard backlight doesn't work? If these chunks of magnet on speakers found theirs way to sensor and OS think that lid is always closed?
Hello Vince I have a 70s or 80s flip clock I'd like to see you try and fix 😊 radio works but you guessed it, it doesn't flip... I'd love to donate
get the trusty ipa out vince :P love your channel
I’m a bit late to this one, but next time you could check if the internal display is recognised by checking the ‘Displays’ section of system preferences, that would’ve confirmed that the display was/wasn’t connected to the integrated graphics.
The keyboard backlight control is not enabled because computer isn't detecting ambiet light sensor which is near the camera and as a result it disables the keyboard backlight at all. And about the audio control when you are connected to a display trough HDMI it outputs audio trough HDMI too and it cant control HDMI audio volume so from outputs options choose internal speakers and volume control would work just fine.
Thank you Ugnius 👍👍👍👍
Display circuit issue, fan is ramped up because the display has a temp sensor that the computer can no longer read, due to the faulty line. it’ll probably be in limp mode like the previous MacBook you repaired until it can detect that screen temp sensor again.
Definitely something to do with the display circuit, keep poking at it. Chime and fan sped is all repairable!!!
Keyboard backlight won’t turn on if there’s enough light. Try blocking the front camera and then turn on the keyboard backlight!
Didn't see you remove the external display while adding your power supply for the back light?
Vince not being pain but can u tell me what your little laptop is u use with touch screen please
You could send it to Rossman repair to fix. It would be cool to have him sort of review your troubleshooting while he explains how they fix the issue and it still may be cheaper than a new MacBook especially if it gets your channel some extra love !
Are Apple schematics freely available or are super easy to find?
I'm sure the big cable on the left was the battery. I was worried it might still be live when you were cleaning that port with a needle.
Not sure what macs have what display but maybe it has an OLED so the torch trick will not work.
Macbooks have LCD-screens, hence the LCD backlight pins that should give 40V.
2017-2019 MBP all had bad batteries. Some ignited. They were recalled.
what kind of camera you use for zooming ?
Nice one mate 👍 so enjoy your videos 📹 👍 please keep them coming 🙏 and here to help get your videos 📹 😉 out to everyone to enjoy 😉 😀 cheers mate you will one day fix it 👍 😀 😉
It may have a problem with the t con board that controls the display
Hey vince. I have a 2019 macbook pro, im not sure if ur willing to sell one of the displays or not cause mine is not really okay at the moment. Im willing to purchase the one with broken camera if thats the new one you got. Let me know please. Thank you and have an amazing day
I wonder if it would be possible to reroute the outgoing signal on the usbc (that you're using for external display) back to the internal one, bypassing the faulty cpu part. Basically converting the built in display to a one that would either take a usbc or mini hdmi input. It would still have to be supplied power of course. Just a thought that might be totally impossible lol.
Maybe replace the ribbon cable between the motherboard and display driver board that clearly had issues ...
Well what a waste of good beer!! 😆
Every time you say "PP Bus" a Louis Rossman gets his wings
Hey dude I think the fans were loud because the thermal sensor is in the battery
Meanwhile my 2013 Dell, one of the crappiest models of the Latitude series the E5430, surviving 6 pepsi spillages already
And you can upgrade the harddrive and add more ram.
In my experience Dells are the hardest laptops to kill
Vince, did you use Phantasy Star music in this one?
it is a shame that the one lines on differential pair are shorted for the display, Still a great video 👍👍👍👍👍👍
Thanks AR, it is a real shame as the initial damage didn't look too bad 👍👍👍

A mate of mine fell asleep in a chair pissed and managed to spill a can of Stella in my laptop. I drained it, put it in the airing cupboard few a few weeks and it worked fine for months lol. An Acer though.
Nice
100% the resistor because resistors don't short so u should check the resistors near the back-light chip
Hi Vince check the mux chip U9850 as if voltage spat back to the display circuit most probably killed the U9850. U9850 is what is between the screen and the CPU and GPU
Thanks Stan, as far as I am aware on this 13" model it goes directly to the CPU. On the 15" it goes via the mux chip because of the separate GPU 👍👍👍
@@Mymatevince I think you are right Vince, I checked it again and it is only the 15 inch that has the mux chip. Too bad they could not put the same chip in the 13 inch az well. Thank you for the videos anyway 🙂
@@stanhristov No problem Stan, I appreciate all help to get this working again 👍👍👍
Nice song
Hi i love watching your videos and my fam thinks im weird because im 13 and watching this but what can i say it’s interesting
Vince, would it be possible to rewire the external display to the internal display, just a thought.
Nice video it is piety i do not understand why apple design those connetors so . That is asking for problems. Keep up the good movies.
Maybe the Macbook has multiple internal Display ports as well and you could use another one
If it runs without the screen connected at all. I’d be tempted to remove the screen to use on another MacBook and keep this as a sort of all in one keyboard + computer without the screen in the way. Or put it in a cupboard as a home server for things like Plex, a web server, Pi Hole server, whatever you like.
Try ultra cleaning the board for about 30 mins. 💯
what the song at the end
Now I'm thinking that the regular priced electronics are handled with a better care than expensive ones
Because the rich people can just buy a new one but cheap one usually can't afford a new one so they keep it as long they can
Was this a failed OC/OV attempt? For a "beer spill", there was surprisingly little damage anywhere. Especially since beer is going to cause an absolute mess internally, even if it was "just a bit".
Especially odd that part of the CPU died out, how did that happen from a spill? Sounds like what happens when you OC/OV too much and a pin or chip inside literally burns out.
