Being Successful takes a lot of work - Nintendo Switch powers on but does not charge Repair

here we're gonna be working on a nintendo switch motherboard we actually have three of them on my bench here but i picked the one that looks the best maybe we can do this one quick the console does power on and you're able to use it but it does not charge zero amps being drawn while we try to charge this console so we're gonna check a couple of things to see why this console does not charge meter in diode mode and we can start with this guy here reading good we can start testing the caps for the m92 no shorts we can test this guy here and this one can go bad because of the m92 or because of the p13 chip that sits on back of the board and what about this one so we don't have a short anywhere on the m92 and if we go over the bq chip do we have any shorts here none so we're gonna assume that the bq is good and also our m92 chip is good just quick physical inspection without spending too much time and as you can see the board looks excellent it's an excellent condition and it was not tampered with before front of the board is intact and if we look on back of the board we do not see anything unusual someone in the comments will mention this dot it's nothing all right so excellent the board is in excellent condition so what is causing the no charge right now the biggest suspect is the usb c port it looks physically good then they look good but it could have internal issues let's look at the port from the inside and i do not see any physical damage onto that port but right now we do not have much options left so right now what i want to do is use the test board the usbc test board i just want to go over the pins quick and see if we see anything obvious i went over this test board in a previous video and i went over some good numbers that we should be reading when testing the points on this board and the title of the video was nintendo switch diagnostic using usb-c test board so right now i plugged the test board onto the usbc port and let's go ahead and measure some points on there to see if we see anything obvious meter in diet mode okay a12 should read ground this one should not have any reading no reading this one should be around 0.5 19 and i'm reading 0.508 this one should be 0.4 oh look at this this one here should read around 0.49 and we are reading a short a8 should not be shortened to ground let's continue a7 should be somewhere around 0.7 0.8 see this is good this is good this one should not read anything good i'm just looking at the numbers this should be ground and this should be ground so right now when i'm taking measurements i'm looking at the numbers that i wrote down from last time and i'm quickly comparing the numbers to see if there's a big change and right now the biggest change that i found is on a8 a8 is reading a short it's reading is short and it's fluctuating actually between 0.1 to 0.09 and that's why you'll hear it beep and then not hear it beep it's fluctuating up and down so we have a problem on a8 so which pin is a8 if we put one probe on a8 i'm meeting continuity mode we do not know if that pin is visible from the front or if it's a hidden pin under that connector right there so that's a8 a8 is right here and this is via that connects the back of the board so a8 is connecting somewhere back of the board so it's possible that we have a problem with our usbc port or it could be that we have a problem back of the board what's on back of the board i mean it could be any one of those traces here so right now i think i'm going to remove the port and then see if we still have a short on a8 what i'm going to do to make our life easier we're going to apply low melt solder on the back fume extractor on and let's apply lemon solder so we can easily desolder this connector without having to apply a lot of heat onto the board because this connector can be removed without adding low mel solder but you're going to be applying a lot of heat onto the board and the board itself must reach melting temperature of the solder in order to be able to remove this connector so why put a lot of heat on this board on a good working functional board and risk something happening i've done it in two ways in one of the videos i removed the port without using low melt solder but the board does take a lot of heat to remove that port just a tiny bit of low melt goes a long way now we're going to go to the front apply some flux now we were able to apply luminal solder onto the legs and we're going to apply luminous other onto the front legs or front pins but we cannot apply long solder onto the hidden pins that are under the connector so we have to be careful when pulling that connector because we have to keep in mind that the pins that are under the connector we cannot reach them we cannot apply low mass solder onto them but usually it doesn't take a lot of feet to dissolve the front pins it does however take a lot of heat to dissolve the legs and we already applied lemon outside onto the legs right so now all we have to do is apply a little bit of hot air and we should be able to dissolve this connector so without wasting too much time let's start i mean look at this look solder already liquefied from here but we're just waiting for the hidden pins to liquefy yeah we do not want to force it i'm just slightly tapping on it see it fell off by itself we did not force it so let's flip the board and we're gonna test a8 where is a8 and look at that the shot is gone the short is gone on a8 so you see that was a usbc connector issue let's go ahead and replace the port and now we're gonna pre-apply solder onto those pads the reason we're going to pre-apply solder now is because we're going to reflow that connector down in place just like that we soaked all those pins with solder and we're gonna use a brand new usbc connector of course now we're going to refold that connector down and then we're going to solder the back legs some people ask why don't you apply heat from the bottom i can do it from the top or bottom if you want to do it from the bottom do it from the bottom i want to do it from the top because in order to apply heat from the bottom we have to extend that board beyond our bench and we are put in an awkward position so i apply heat from the top whenever i can for heat sensitive connectors i do it from the bottom like maybe nintendo switch lcd connector or an sd connector i do it from the bottom i have the connector a little bit pressed down so the camera went out of focus for a bit and we should be good solid solid and we just did a better than factory jump let's go ahead and solder the lugs on the back sometimes i get comments like you apply too much flux i mean we are working under a microscope it looks like it's a lot of flux but i do not know why people are concerned if i apply a lot of flux or do not apply a lot of flux nobody's paying for my flux i can apply as much as i want and what you see here is not a lot it's only a tiny drop but it looks like it's a lot under the microscope i mean this is a size 201 component right here 201 size smd component we are dealing with microscopic components and the flux is just a tiny drop and we're gonna do this one and finally we're gonna do this one and we are done nice just added on top of the 100 other gpus that we have expedited every single one of them is expedited let's plug this in and we're going to test a8 and see what's going on meter in diode mode and very good very nice we do not have a short anymore all we have to do is plug the battery in and see if it charges i mean look at those legs the joints soldering is perfect mercedes key all right just put it over the six million keys that we have on the bench here and hopefully we'll get to it soon all right very nice look at those nice joints very nice everything is nice and clean feel the extractor off and okay so we tried the board and it's still the same problem we had a short before and now we do not have a short after we replace the connector but the board is still not taking a charge i mean previously having a short on a8 of that test board could be a lot of things it could be the m92 chip it could be the p13 chip it could be a lot of things i know from experience that m92 fails a lot on this board so i think my next step would be to replace m92 and see what happens it's just a tiny bit of flux we're gonna replace the chip we do not have a short anywhere around the chip but i know the chip fails a lot on switches so i'm gonna start with this one i mean this one's gonna be a tough one to figure out because a lot of things could cause the problem and if it wasn't for the usbc test board i would not know that there's a short on that particular pin so it's really a priceless tool a priceless cheap board it's only it's only five dollars you can purchase it off our website i mean a lot of you already know and a lot of you are already customers but i keep mentioning this for all new users one customer commented because a lot of times i mentioned what we have for sale on our site and he said i feel like i'm watching one of those shopping channels a lot of people support the channel by donating a lot of people support the channel by commenting liking sharing a lot of people support the channel with a good word of mouth and majority they support the channel by buying stuff off our site i mean i spend a lot of time making those videos it takes a lot of time and a lot of people they appreciate the time spent to create such content i really thank each and every one of you who support the channel in one way or another like i said whether it's a word of mouth a simple comment is simple like or if you sent a device here for repair or if you purchased off our site all that is a form of support and that's why our business flourished because of you sometimes i stay up till three o'clock just to edit and upload the video and i do this every single day almost every single day i mean i feel bad sometimes because when i go home i should spend it with the family and i do but i play with the kids for like an hour hour and a half and back of my head i'm thinking i should start editing and uploading that video and i'm sitting on the computer editing and my daughter comes to me and tells me good night she's going to sleep and i feel bad so i leave everything and i go sleep with her for a bit until she falls asleep and i continue working on the video i mean being successful is a lot of work it's a lot of work we have a lot of business we have a lot of customers not just because i was born like that it takes a lot of work when i have somebody that tells me lucky you you have a lot of customers and my lucky day is when i have one customer on one side i feel bad for that person and on the other side i know that that person should work harder because hard work does pay off you just have to be patient just like somebody who wants to start a youtube channel they wanted to grow from zero to 100 000 in one week and they don't have the patience they upload the first video the second video the third video the 20th video they're not getting any views and they just give up it doesn't work like that you're not going to get any views because nobody knows your channel just keep uploading quality content and people will eventually come across your channel i started with nothing zero subscribers of course i got help from nobody and the channel is doing very good it's actually doing a lot better than channels with a lot more subscribers and the job is down here and one way to find out we have to plug a battery and see if that console will charge let me see if i can grab a battery and i'll be back okay so i went ahead and grabbed the battery and we'll test to see if this battery will now take a charge and i have our usbc charging cable here along with the amp meter that should light up if this board will take a charge yes yes 15 volts at zero point what happened okay 15 volts at 0.8 amps being drawn by the amp meter awesome 0.85 0.83 awesome awesome one more time 15 volts at 0.8 amps the job is done the console is fixed so a short on the a8 pad of the test board led us to replacing the charging port and the chip i mean there was no clear indication to what was wrong with the board but i just took an educated guess based on my measurements on the board we did not have a short anywhere on that board so the first thing that i thought was let me remove that port and solder another one and see if the short will be fixed and the short was fixed but the board was still not charging after the replacement so i took another educational guess and replaced the m92 chip and that fixed the problem now if the m92 chip did not fix the problem then probably the next thing i would go to is the p13 chip because the p13 chip also works hand in hand with the usbc port so that could be a suspect maybe i'll change the bq chair afterwards the bq chip is also very important but the fact that i did not find any short anywhere next to the bq chip led me to believe that the problem is not the bq chip the good thing is the problem is now fixed so that's it i hope you enjoyed this video don't forget to like and subscribe and we'll do something else in the next video [Music] you
