Trying to FIX: Nintendo Switch Lite BACKLIGHT FAULT (Black Screen)
HTML-код
- Опубликовано: 28 авг 2024
- Hi, in this video I attempt to repair a Nintendo Switch Lite with no backlight. The Switch Lite is working but has a black screen so you can't see what is being displayed. I purchased 2 Switch Lites from eBay for £199. This is the 2nd video where I am working on the grey one.
Remember that this is just for entertainment and I am not an expert in these repairs. The processes in the video may not be the best way, the correct way or the safest way to fix these things.
I do love fault finding and trying to fix broken things so I hope that comes across in this 'Trying to FIX' series.
Many thanks, Vince.
Why are these videos so calming. I love watching these repairs late at night. I makes me feel so calm. I luv yo videos mate
OH MY GOD YES THAT IS WHAT I THINK TO!
Late at night, hmmmm
YES
It's the calming British accent!
Probably the chatting voice plus the classical mhsic in the background. Try playing classical music instead and see if that helps you sleep better at night
you have the perfect quality for such a job, patience!
This guy is amazing. From helpful videos on consoles like Nintendo switches and switch lite's to fixing different devices this guy has the whole package!
@My Mate VINCE 38:29 You would not get the 17V on the Backlights is current controlled so with no backlight connected it would not generate the voltage needed for backlight the chip monitors the current on the led`s , Great Video 😊
Iv had this situation with the current sensing circuit on TV backlight arrays also, it can be confusing
@@reacey Yes very confusing sometimes
Hi. my Switch Lite is only feeding 4.01V for the backlight. Would you happen to know what is this chip you're mentioning that monitors the current led's? Would that be the IC that My Mate Vince desoldered from the board (the one with 9 pads underneath) in the video? I get no video and no sound. I appreciate your help (:
@@Rodox2k10 You would first need to get video don`t think backlight would work if you don`t have video
@@AnonymousRepair It wasn't giving me anything, but upon further inspection I discovered the four bigger caps around MAX77812 (the one under the CPU) were shorting to ground and I've ordered a replacement chip. Maybe it's a short-circuit I might be able to restore this Switch Lite from.
Epic repair! I have a meter to test inductors - if you had a working inductor to send me I could measure it! Do you dare remove the one from the working one lol! I hope you can find the connector and coil - this one will then live again!!! Note: Always kapton tape over connectors when using hot air nearby, and when heating from underside, bear in mind components on underside may "fall off"! Great job on this one!
GadgetUK164 - Retro Gaming Repairs & Mods Great Advice, I love watching your’s and vince’s videos. Persuaded me to open my repair shop!
Those ribbon connectors, if you are missing the flip down anchor, you can use a thin piece of plastic, like a cutoff sliver from a blister pack, and slide it in, on top of the ribbon cable Vince. Does exactly the same job, and has saved many a motherboard/keyboard ribbon problem.
Would you mind showing that on video?
@@Rodox2k10 I can, yes. Dependant on what I have knocking around, at the moment. But I will try and sort that for you.
I just wanted to say your video really helped me diagnose what was wrong with my Lite. I swapped shells and buttons and my screen stopped working. After watching your video I realized the lid came off my backlight connector and some pins were bent. Risky business swapping the shells.
The black residue is carbon winch conducts electricity. Nice job mate.
ok but why would it be in the connectors?
You can measure a good coil, I believe that your Mega 328 tester has the function to measure coils, they are measured in millihenries.
Hey Vince, a simple Needle scraped over some sandpaper, do a good job for cleaning the tiny connectors pins. i use is that way all the time. Just a hint, like ur work
The plot twists in your videos are better than most movies and tv shows
Hey Vince,
In regards to the sideboard with the missing connector lock. My NEW 3DS XL had the same exact connector, albeit with more pins, but I unfortunately damaged it. But what I did to rectify the issue was cut a piece of electrical tape to the size of the width of the pins on the cable itself, but place on the opposite side of the cable where there’s just plastic. That way, it becomes more of a friction fit style connector.
I did this to my 3DS and it has been fine ever since. But of course, I’m not entirely aware of any additional problems your unit could have.
Vince I tend to use croc clips with some fine wire for small things like those pins . I just clip them to the leads and use them like they were the probes. I wonder if maybe a pair of small sewing needles soldered to some wires to the croc clips would be better to get that finer point though. I just thought I'd share that one as I use it quite often when working on laptop traces and tablets.
Yeah I do similar, the crocodile clips and sewing needles, works well.
It’s like a proud moment watching your videos in the past few months! Your fault finding has improved heaps and bounds, crazy to see how far you’ve come in the last couple of years! I remember watching through my fingers sometimes when I could see you about you mess up but now I watch with confidence that you’ll find that fault and fix it! Well done vince
I've seen replacement fpc connectors like those for the 3ds on eBay and aliexpress . Not sure if they're the same number of pins though. The smaller of the two could be.
Revisiting this video and the one where you finish repairing it and taking notes as I have a costumer with similar failure mode.
Great videos Vince. Pretty much watched everyone you make.
always been interested in electronic repairs, and you make everything easy to understand to a layman like myself.
Lock down not half as bad when you have these videos to watch big thumbs up
Thank you Vince to make fun our quarentine ! (Bip Guy by my wife)
Vince mate, you need to inject voltage into the board and see what heats up either by putting ipa on the chips and watching it dissipate or getting an in-fared heat detector device, its the only way to reasonably find a fault of that manner. plus i do not think the back-light will show 17v without it being connected as i'm 99.9999% sure they are current controlled and it actually has to be on for the 17v to show. another note Coils don't short usually, they fail open.. could be the coil though doubtful
(10:38) - Sorry Vince, but that is not *_"corrosion"._*
_NOT_ *_"water damage."_*
It's flash-burn damage caused by electrical arcing.
My guess is that all these arc burns happened at exactly the same time.
Specifically, when the device suffered it's fateful impact.
That is, when it was thrown against the wall in a fit of pique.
>
No, arcing on the connector is what Rossmann has to deal with on MacBooks xD
@@joshm264 Haha!
Very funny.

Wait a moment, why does he attribute a screen with no back light to the flex cable? Isn't this cable JUST supposed to connect the left mini board (Left shoulder buttons, D-PAD, Left Stick, Minus and Share button) to the rest of the board? Or is that flex cable supposed to do something else other than that?
My Switch powers on normally and gets to the welcome screen. After some time of inactivity, it goes to sleep. Upon pressing the POW button, it immediately shuts down. But trying to wake it up with the HOME button (right motherboard) works. I found that this cable has a broken via, could that be the reason or something else?
Well done Vince in getting one final Switch Lite together. I hope you will be able to update us all when you be able to get another damaged Switch Lite.
Absolutely love the long videos. Well done Vince for finding the fault. Thanks for your content. Take care, stay safe.
Impressive troubleshooting, Vince. I believe you _will_ get this one to work for sure. Well done, sir!
Wouldn't the spares from the job lot from a week ago work for the lite?
hey vince, big fan.
I do component level repair in laptops, from my experience, any coil that fits should be good, it's just a coil so you could even bridge it with solder and it should still work.
Also, I know that 3ds boards have verry similar connectors, you could try one of those.
Cheers!
~Faceless
They do have similar connectors. But when I took mine apart to fix the touch screen I couldn't find connectors looking like the one Vince would need
Once again get to come home from a risky day at work and watch you try and fix something keep it coming makes my day so much better keep staying safe you and your family 🤪
Once again a fantastic in depth video. I really do enjoy these long videos. And hope you can fix this switch. Just glad you could put the yellow switch bits into the grey one. That’s a result on its own. One question I do have is can you point me in the right direction of a budget multimeter that beeps for continuity? Want to repair my TV and figure out which SMD is bad but don’t know what budget multimeter to buy? Many thanks and keep up the great work!!
Also the diode doenst seem ok. The one in the good board was measuring different values. Also. Measure both sides of the coil to ground.
PS, I don't think it's the bga bue measure voltage of components around and compare with a good board
Nice that you fixed it.
Show me a close picture of the connector and coil so I can see the number of pins. There is a similar one in the psp 300x
Vince that coil is an inductor. Inductors can be measured in ohms with a volt meter.
Hi Vince thank you for uploading really love watching your content it’s a real inspiration for me so thank you again stay safe all the best!
Your component tester will tell you how many Henrys, if you take the inductor of the good one. Alway enjoy your vids keep them comin.
A really good job fixing the previous switch, and finding out how to fix this one.
You've come so far since your first switch.
this helps me stay sane during quarantine
Hi Vince, I think you need to work on your short detection, there are multiple ways to find shorts, visual,heat,experience, generally only caps and chips fail short, inductors/coils/filters fail open.
Yeh i learned to inject voltage into the shorted line and see what gets hot, you can even use a battery if you don't have a power supply, or one which you can control the voltage and current output on, also covering the board with lighter fluid before injecting the power is a neat trick, you see the petrol evaporate on the shorted component easily
I admire your tenacity but at 30:33 it was hammertime :) I bet if you took long enough you could find a fault with Cindy Crawford, love it when your excited voice rings out, I can almost see your face lol
It s impressive how ur able to do such a good job on the ground
Respect for ur back lol
hey Vince i just wana say i love your videos and your definitely not the switch killer anymore keep on creating awesome content
Another fine addition and more than acceptable editing/run time. Thanks as always Vince :)
Excellent video, Also Awesome choice in music, Vince
Hey Vince, you should invest in a 3d printer. I'll bet you could 3d print a lever to put pressure on the ribbon cable and it could come in hand in other projects.
Great video vince your video made my day better. I remember you said last time you had to change the charge port and it would only charge one way. If the charge port on the other board works properly you could swap it over and put it in the other switch lite. Keep up the great work with the videos
Hey Vince.. A good idea for super cheap consoles, which is something I just did. Call a local game store, and ask if they have broken consoles they will sell. I just picked up like 10 for 10 each. Not a bad way to get stock for videos.
My mate Vince, you're the best. Really helped me sort out a project with a similar problem here.
The fact that you measure 3.7V after you replaced the inductor with a piece of wire does not prove anything. It's a boost converter: en.wikipedia.org/wiki/Boost_converter . Even if the controller chip/switching device is broken you'll still measure supply voltage - which is the 3.7V battery voltage. (Also, replacing the inductor in a boost converter with a wire is a great way to kill the switching device if it wasn't dead already)
Hi Vince,
Retrosix in the UK sell these ribbon cables now and other switch spares.
Hi Vince, I had a lid on a connector snap-off on me when replacing my laptop screen, but I came up with a solution. Firstly position the ribbon cable where it should go in the connector and stick it down with kapton tape just in front of the connector to hold it in place.
Then find some stiff plastic about 1mm diametre and cut a rectangle piece the size of the opening of the connector twice as long as you need.
Then bend it over and make a crease at one end and the opposite end you pinch and close them and insert it into the connector and tape it down so it stays there.
The springiness will hold the ribbon cable down in place making a proper connection.
This worked for me and it is a bit of a fiddle to get it right but it worked for my laptop and that was three years ago.
Just a thought, you could remove the inductor from the working switch lite and test it with your little 9v multi component tester to find out what the value is? I've never needed to measure an inductor with mine, but I tried a spare one and it worked, it came up with 12ohms, 9.59mH, so you could find out what the value is supposed to be with that. As for the connector... I don't have one to look at, but if you google FPC connectors, you might be able to find one that is the same.
It is so awesome to watch you work and fault find! I lost one of the lids for the ribbon cable that connects the two boards. Can these be bought?
7:55 wow
I gotta get me one of those fiberglass Pens.
That little BGA is most likely the load switch for the (17 volt) backlight power. Given how toasty it's apparently got, due to shorting, I'd be surprised if that chip isn't completely roached.
I do think ebay should add an extra box for item condition and call it something along repaired, attempted repaired or tampered with ect.
This way if you buy something without this box ticked at least you could leave feedback/get a refund
Very Helpfull thank you. I just got one hera and i cant compare or read out Voltage on a working one.
Always enjoy your videos. Always something to learn from you. Thank you
I don't much about this all works. But if the ribbon connector is damaged why can't you run a thin jumper wire. Or run jumper wired to the connectors and or the pads the connector is on. As always love the videos can't wait for the next one
Hey Vince thanks to you I pulled out the multimeter I had. I never really thought of a use for it but now I'm using it to test batteries I use for my flashlight UM TORCH for work. I wish I personally had a better use but it's still fun and useful.
don't forget batteries recover voltage after some time and a lot of batteries can be still faulty even though voltage is ok. I had experience with 9V batteries, it shows like 8.8V but it couldnt power simple dc motor lol, seems like it had not enough current.
@@djedvis Ohh that makes a lot of sense thank you :) Yeah I tested an old AA battery I knew to be bad and it still showed 1.5v which confused me. Still much I need to learn. Thanks again!
@@Night-Jester i am also very new at this but i love this youtube channel which makes repairs look very easy and there is a lot of interesting things to learn. Sadly I do not have broken devices today... I wish i had so i could try to find the problem.
Great video as usual!, just a curiosity.. what is your youtube equipments? camera, mic, etc..
Thank you
Carbon tracking can cause weird shorts that don’t seem to have a reason. If the scorch mark went under the connector and left soot between 2 pins that could be the short in the connector you couldn’t find.
Awesome job vince . Where did you buy your parts?
(clapping hands) well done sir! Persistence and perseverance!
Hi Vince. Your logic thinking is perfect m8. Confidence is high. Proud of you. 👍
Nintendo banned me for no reason lol and I saved for one whole year and now I can't play a single game so your videos are fun to watch you don't even know how sad and angry I am at nintendo
Vince, look for FFC/FPC board connectors. It shouldn't be too difficult to find an appropriate replacement. Number of contacts and pitch are the key parameters. You should be able to find flexis at standard length too but finding one to suit might not be as easy as a connector.
Enjoyable video, was watching it while dissassembling and cleaning a ps3 controller.
You can actually replace the connector using hot air and leaded solde bcz the leaded solder will melt before the plastic melts you need to clean out all of the unleaded solder to replace the connector without melting it you will clean up the pads with soldering cooper thing I'M NOT GOOD AT ENGLISH AT ALL
I think Vince has some leaded solder, but technically speaking, we aren't allowed to buy it in the UK. So it's good to come up with alternate solutions too if you don't have access to leaded solder.
MizuhoChan really? I've always but my leaded solder rosin core on eBay
@@NorthCamZ Article 67 of REACH shows that legislation has been passed banning the sale of any lead bearing materials to the general public. This includes soft solder. The maximum allowable content of lead is 0.3%. Above this figure, all such materials are regarded as toxic.
Why is leaded solder banned in UK? I don't understand.
@@constantinjitariu1439 because lead is toxic, cancerogenic, both in production and to the end users.
Why does it feel like I'm getting my switch lite from fixed by this guy
Use the lid of the broken connector to at least fix the sideboard one! it should fit! same pins and orientation
Doesn't surprise me it turn out to be coil that bad. As iPhones pretty much something coil usually goes first. That BGA chip likely the backlight driver as on iPhone 6s similar way they do the backlight.
Now I have to find that fiber glass pen as does great for removing burn and corrosion.
Great vid. Just keep the gray SwL as the working one for now.
If you have the time and patience you could use thin wire and solder the between the two boards to test instead of using the ribbon cable, you have to replace both connectors anyway, no point in buying spares if you dont know if there is more broken components
I think because its been dropped the ribbon cable has come out a bit and causes a short i think this is why the ribbon cable is burnt
VioletDragon Projects I think that’s about right but what I originally though was it was dropped ribbon came out someone went in and tried to plug it back in they reseated it a bunch the latch broke they put tape on it the contacts shorted it welded some pins together and that’s why it had a few shorts on the caps and why it was burnt
Vince I clicked on ur video and was watching it very good and very detailed, I don't even own a Nintendo switch 😂 but as you always do great videos I watched it thanks, I remember you from back in the day when you was Mr telephone 📞 and I also use a RJ45 instead of a RJ11 👍🏻
Well done Vince light always works for me
17 volt that’s not bad, led tvs use like 180v + to drive the leds
I may be showing my age, but try CRT's. The HV is about 25,000 V. No amps behind it, but it gives you a mean bite if you put your fingers where they shouldn't be.
Bobbywolf64 oh yes pretty much like grabbing a damaged HT lead on an old car lol 😂
That was really entertaining. Thank you, Vince :)
Brilliant, thank you. Great work as always
You can still measure the coil from a working one with the LCR meter. Current ratio could be an issue but 150mA or so should do the trick. I dont think that backlight will disipate more than 2 or 3W. Just saying ....
Hey Vince, these connectors have come up on aliexpress today, search for "switch lite power connector" Theyre like £9 for 2 of them though.
Dear Vince many thanks for great calming content in this unusual times !
Hay Vince
My names Al
Iv got a Wii u and your videos have helped.
I’d really like to down size the Wii u game pad into a smaller shell.
Do you think it’s possible to repackage the game pad into a smaller case.
Have you ever done this ??
If you have an inductance meter or LCR meter then you can measure the inductor on the working switch lite.
A wild guess but i believe the previous owner experienced drift and opened it to fix that but in the process he/she broke the connector and when he/she put it in again it didn't go fully in or was jumping around so it caused the arcs...
Wow! You saved my nintendo switch i thought its gone :D
@My Mate VINCE take the white lid off the broken connecter and put it on the small 2nd motherboard because the connecters are both the same
Have you checked to see if that short is actually still on the connector? Maybe it was that black corrosion you scraped off after you removed the connector, iv had conductive corrosion like that before cause a short. I only say that just incase you could put that connector back on with heat from below the board
great job mate. never give up !
Thank you for your videos they are just great. Question Have you every tried to repair a Raspberry Pi 3b ? if so can you give me a link to the video. Thank you
That's some nice detective work there. Honestly it's a bit surprising to me that the 17V path isn't more isolated from the rest. You could perhaps take out and measure the inductance of the coil from the working one. And if you can't get some new connectors (and ribbon cable), perhaps you could use some tiny wires instead of the ribbon cable, which was in a bad shape anyway. When you use that fiberglass pen on the contacts, you remove the gold plating, which could eventually lead to oxidation and bad connections at a later date. Solder might also make it uneven enough so that the connection on the other contacts become poor. It's damn unfortunate with the broken display though.
I thought the same but Dave (eevblog) and louis rossman have videos showing the same issue on apple products, think maybe it was a MacBook, high voltage pin right next to a ground pin. I don't know a lot about electronics at all but guess maybe it's just common now with all these super high density boards
@@ekens6344 I'm no expert, but it seems a bit sloppy to me. One would expect engineers hired by high-profile companies to do a better job when designing these things. I've seen some of those videos you mention, I think.
interesting for the cable to break like that!
Hi Vince can I ask you what type of working pad that you have because I would like to get one myself as I can't do much anymore because I hurt my back and have had a major back operation this sort of thing would be good for me to get into and I am quite handy at this sort of thing look forward to hearing from you kind regards Jamie Sutherland
With the black marks on the PCB it's possible the short was internal to the pcb
the no video issue could be a result of either a faulty PI3USB or the filters near it. Give this a try. There doesn't have to be a shorted cap for it to be bad.
vince if you have any new 2ds xl broken boards i am sure the coils or inductors are smaller in size
@My Mate VINCE You wouldn't happen to know how to remove the little WiFi connector bits from the ends of the antennas would you? I stupidly managed to snap them off with my thumbnail when I was doing a tear-down and fan replacement at quarter to 2 in the morning and no ones been able to give me any insight on how to get them out without causing further damage. I'm really OCD when it comes to my laptop not working 100% as it should. If i can get those little pieces out all II'll need to do is replace the WiFi card. I think a pair of tweezers like that would really come in handy! Please help!
The only thing is, I'd want to keep the black one working. So, 16 minutes in, and you are done; as far as I'm concerned!👍👍
Use an LCR meter to measure the inductor on the working board.
Good morning Vince!
We have a question!
How many consoles you make normal?
Great detective skills
Thanks pal, i really enjoyed the vídeo
vince i seen on ebay that you can buy that coil from a person from greece
