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.
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
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.
40V right next to data line often exposed to spill damage. some call it a design flaw, some call it marketing genius.
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.
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.
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 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.
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 👍👍👍
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😁
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.
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 😆
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.
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.
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.
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!
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!
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
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
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.
👍👍👍
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 laptop fixing series is my favorite series!
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
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.
The fact that it started displaying onto the external screen straight away when you plugged it in using HDMI means that it did not detect an internal monitor. If it had detected an internal monitor, you would only get external picture in clamshell mode whilst being in the boot menu/flashing folder message :)
Same reason why the keyboard backlight is not working, it needs the ambient light sensor (which is in the screen) to work.
Thank you Oskar 👍👍👍
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
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 👍👍👍👍
Still love watching these Vince.
You are my hero with these videos. Keep it going !
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?
19:53 if you get that Retina screen working you will have a better view of that laptop because that screen is very nice
I hope you making a part 2 or something like that! Good video. Thanks.
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 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?
35:00 where you were pointing on the socket directly below that the capacitor looked crusty worth a shot
Louis Rossmann has been yelling at Apple for years now because of this stupid design decision to place the HV backlight pin on the display connector right next to a signal pin. One improvement with this 2019 model appears to be that it doesn't outright kill the entire CPU, but 'just' kills the IGP.
Why Apple insists on keeping this design flaw in place since at least 2016 is anyone's guess, but it might make for a nice kill switch whenever someone spills some liquid on a MacBook. Which is something that is apparently guaranteed to happen at some point. One of the standard jokes among Apple repair folk is that fuses are so precious at Apple that they'd rather sacrifice the machine rather than have a short between HV and a GND pin blow a (display) fuse.
Definitely a good reason to get a ThinkPad T-series, I guess. Those you can pour a few liters of beer on and you'd just be annoyed at the beer you wasted while you shake the drops out of the keyboard :)
🤣🤣👍🍺 Thanks Maya
Having "high" voltage line next to expensive and important chip line can only suggest two things. Incompetence of the designer or intentional failure point.
@@pvc988 Being that it is apple we are talking about, I would say that it is intentional
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.
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
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.
Shame the new screen didn't work Vince. I would have had to buy it as well just to know for sure.
Adamant IT would be a good youtube channel for you to watch he does quite a bit of macbook repairs
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
Every time you say "PP Bus" a Louis Rossman gets his wings
The one thing you do not understand. It is that beer is one of the most corrosive liquids. I would have cleaned the board on both sides. When you add power, you accelerate the corrosion.
Did you check the traces of that display connector it might be broken in some places
100% the resistor because resistors don't short so u should check the resistors near the back-light chip
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.
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 👍👍👍
@@Mymatevince 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😁
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 👍
Well what a waste of good beer!! 😆
Love the upgrade in audio bro
You have to remove all the metal shards from the speakers in order to prevent further damage. Don't push the speaker membrane like that. Use a strong magnetic screwdriver to pick them all up
Hi Vince. Maybe Hall Sensor went back? Computer thinks that the lid is closed, so no backlight and image is provided.
Great video vince, really enjoyed watching this one. 👍
That’s a shame that it isn’t working. I suppose replacing the CPU is an impossibility. Great video again though Vince. Cheers Graham
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.
Interesting video this one very enjoyable your fixes got me intrested in soldering again but not as good as you
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.
In terms of the SSD, all touchbar models have a soldered SSD, and i believe all MacBook models from 2018 have soldered SSDs
The non touchbar 2016 and 2017 MacBook pros don’t have soldered SSDs, however the SSD on those is proprietary
Another thing, the keyboard on that one will be a “butterfly” keyboard, that type of keyboard has known issues which can cause the keys to stop working
Thanks Pineapple 👍
It's only proprietary because it needs a special adapter IIRC. Hugh Jeffries has done SSD replacements for those using an adapter.
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
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 !
great work Vince!
Hey dude I think the fans were loud because the thermal sensor is in the battery
I’d mount that board to the back of a monitor and make myself and iMac out of it. Use usb keyboard and mouse lol
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 :)
Maybe replace the ribbon cable between the motherboard and display driver board that clearly had issues ...
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.
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.
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
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 👍👍👍
Metal and beer?? Sounds like a rock band! 😉
2017-2019 MBP all had bad batteries. Some ignited. They were recalled.
Vince, would it be possible to rewire the external display to the internal display, just a thought.
Vince: *(Turns Off Macbook)*
MacBook: *(Defiantly turns on again, like a rebellious teenager)*
Me: *"Go home MacBook your drunk!"*
good job mate.
I hope the beer was an IPA....!
Hi, Why dont you get another CPU? From one of your broken boards and swap it over. To see if that fixes the problem. I know your upto the task of doing that.
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
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.
Try ultra cleaning the board for about 30 mins. 💯
What was the fault with the a2179 after?, great videos!!
1st class video to watch thank you take care kind regards from me kenneth
Maybe the Macbook has multiple internal Display ports as well and you could use another one
awe... Your daughter needs to wait for the next one I guess.
Great video as always =)
What model is that microscope. Want to buy one but not sure what kind. Thanks and it is a good video as always
Didn't see you remove the external display while adding your power supply for the back light?
Booom! New video is here, thanks Vince.
yikes. that might be a bad day for that 2019 MacBook Pro.
I call for a Louis Rossman collaboration video.
To me Apple's ain't worth the money. You spend thousands on a machine, that is a bastard to fix when they go wrong as everything is soldered in.
Today this is true! My 2008 MacBook however still going strong 🤣
Spilled beer into a Mac?...that's alcohol abuse, I hope the beer is o.k.
At least we can assume it was an exclusive craft IPA from a remote microbrewery, it being a Mac owner and all.
Your LED's will never draw any current or light up at that voltage. A retina is around 50V dunno about these. If the external display works then perhaps there is a way to trick it to send the signal to that pin with missing signal? If i were you i would have not purchased the display with bad camera. You will never separate the lcd to repair the camera or cable. You should have bought another broken macbook locked to the cloud or broken display and made one good from 2 bad. Then resell the left over parts for spares.
fans to full speed usually is a sensor
Nice song
Are Apple schematics freely available or are super easy to find?
Thanks for another great video
It may have a problem with the t con board that controls the display
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.
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.
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
