#iphone #repair #tech - Наука та технологія
You're AWESOME. As a tech myself, I really like what your are doing for your viewer. Actually picked up several tips from you. I really appreciate everything you're doing.
just absolutely amazing videos. the most consistent and thorough of their kind I've found on youtube. Hope business is booming man because you deserve it.
Still enjoyed video even with your problems. Your probally the most genuine person I've come across.
I overlooked this comment somehow.. I like to be able to sleep at night so if something isn't right, I beat myself up over it. I've recently learned to only let stuff bother me if it is important. wow A long 30 years.
Thanks for taking the time on these videos.... a lot of the time i just leave them playing whilst i'm doing repairs myself. (of course very helpful too) : )
That's really good to know! That's for watching and commenting. Comments like that will keep me going for sure. :) I'm hoping to make time to upload this weekend. The shop has been so busy it's been tough to make time for UA-cam.
Great video and content bro definitely helpful toward TriStar fixes for future iPhone technicians
Extremely professional...Loved ur attitude and hardwork...And liked ur sense of humor...Keep it up bro...God Bless...
Thank you for the kind words =) I'm gonna keep posting videos for sure!
good explanation...................... especially compared to many others that rush through the job and play annoying music and never actually talk........... good job
awesome video Jas !! hey a question i have a iphone 6 here the lcd fades looks like a loose connection i have changed the lcd fpc still the same it comes and goes but atv the moment i get nothing no backlight or display have you ever had this before ? reminds me of a tv lcd when a connection is loose and the picture fades away
hi, you seem a very nice, happy and helpfull dude. I am ammature but I will try to do it !!!
I have 3 little questions...
1. Should we add flux before installing the new one ?
2. Shall we worry not to overheat the new one ?
3. how can we be sure that all 36 pins are connected ?
hello bro thanks for the video just to know the component around the iC will not effet the work of charge its just information ;) thanks for the great work
If you do a chip on a macbook board vs an iphone board do you use substantially lower heat on the mac board chips? I read somewhere you use around 260 C instead of 375 C.
hello i can ask how much temperature to disconnect ic on the 350 are fine and to reset the 260 and i can clean directly with braid the pond without adding any other pond to take away the old thank you i hope i have news
I am going to replace my ic u2 charging chip on my iPhone 6 plus. Can you please give me step by step instructions on what you're doing in your video and give me a list of what tools and products I need to purchase to do the replacement? and what is that yellow tape you're using?
Hey maybe you can help. Had a phone where customer used a cheap charger. Stopped charging/turning on. Would only boot loop with external power/charged battery.
Replaced Tristar. Phone boots normally goes to home screen, unlocks, everything fine. Except PC doesn't detect it and doesn't charge or even show charge symbol. Think it's a bad Tristar replacement chip or something else?
Very nicely done
Hello how to be sur that's is the tristar issue ( un case of batterie drain ) ?? i actually check that voltage on the capacitor arround but is if the right way ??
How do you determine the the good side. Because as I could see, I could not know. Is it upside down or else. Is it what it’s written on the chip?
Hello, what is the temperature for desoldering with the hot air station, please. Thx
How to tell the correct chip orientation when the original chip is already pulled out?
Hi jason, i got 0.4 v and the battery connector, do i need to replace the charging ic
Miss your videos man
Is TRISTAR_TO_AP_JTAG_SWCLK important? I accidentally ripped that pad while wicking it... It's the pad right under the ground A6 pin at the top left corner of the tristar ic.
Really good tutorial. Just one question, because of the tight tolerances between each solder ball how are you sure they all line up ?.
It's tricky but surface tension makes it possible without being perfect. As long as it's within a certain margin and none of the balls are bridging pads, surface tension will align all of the balls & pads at the same time when they melt.
You love pulling on them chips!1 :D make me freak out every time man lol
hi sir, thanks for your help, i changed many times u2 ic always done but this time i don't know why i changed 2 times ic but still battery darin fast, i changed battery also,,, can u please give me solution......
what would happen if 4 pins on the motherboard ic they got damaged could be make a jumper with out ic
You were talking about getting a microscope. could you provide a link to the one you were going to get?
hola amigo tengo un problema con un iphone 6 que no me funciona el boton hom y se activa solo el control de voz me puedes ayudar no e podido encontrar nada para eso
You gotta do one on stuck gas gauge.
I have replace a lcd to my iphone 6 and i have took of the battery connecter before starting take off the lcd and i took the lcd of i check the new one everything was look ok and i replace the screen with the new one
Once i put the screen on and the battery connection back and i press the button
The phone wasn't turning on
I have plugged on charging and nothing
What do you think is the problem help please
Nice work i like it 👍
Could you put kapton tape over the caps, two strips masking off the sides with components so if they float they won't drift or get pulled by the goo on sticking to the IC?
My iphone 6 plus battery drains so quick and sometimes turns off when battery is 5%-10% left is this because of this IC becomes faulty ?
Sir can ask you..what kind of microscope stand or bracket
Sir I am having iPhone 6s plus the touch id is getting hot and iPhone 6s plus is also having a battery drain issue the icon add finger print is greyed out I have restored it two times which hardware I have to check now
friend can you tell me what is the type of your microscope and how much it costed you
Hi.. my iphone 6 discharging its battery even though its not using... the battery remains for 2 hrs even it s used or not used ... fingerprnt sensor z also failed in this.. its not the battery issue
What would b th problem
The repair was excellent and the customer was pretty happy too I'm sure. I' gonna throw a critic but please don't take offense, it meant to be constructive : I can tell you a perfectionist and this camera problem annoyed u but u don't need to mention it 30 times !! :-) As a viewer I prefer when you explain more about the process of the repair, for example at one stage u explain that u prefer to clean the pads with a normal iron and not the micro pencil, that is a very valuable information, also the thermomass of the pcb that again is very important. So that was just my 2c, and I want to thank you for taking the time to post those videos. I really learn a lot. Oh and yes I just ordered my microscope from Amscope on Ali coz Amscope US is a ripoff (if u ship to London that is) and guess what I choose a SIMULFOCAL!!!!!!! God bless :-)
Thank you! Criticism accepted! You're not the only one to tell me the exact same thing so it must be true. Hopefully I've improved some on more recent videos. Thanks for watching and commenting. :)
I'm glad you can take some constructive criticism about repeating your issue with the microscope. Coz' a lot of folks here watching these repair videos want to learn and don't really care to know about how much you bench press down at the gym this morning. And this seems to be becoming a trend with the other repair videos. While doing repairs, they talk about their fight with their gf etc. I'm like :( wtf! Can we go back to, you talking bout what you're doing with this phone you're working on. So, I've subscribed and always looking forward for the latest repair you're doing. Thanks.
having same problem need your help
Thanks Jason. WRT to your comment about the one eye and depth perception using the microscope. I only have one usable eye, do you think I will not be able to get into this industry successfully?
I think if you have adjusted to seeing from one eye, depth perception may not be so bad. You would likely still be able to work under a microscope.
I have an iPhone 6 that was not charging after water damage. Phone could boot with a good battery but could not charge. I tried to replace u2 ic and rehot u1401 ic and now phone is completely dead, iTunes does not recognize it. I try to measure the volts of the capacitors near this chips and no volts, no sigh of life!! What i did wrong? Can you fix this if i send you the phone? What's the possibility to repair this? Thank you
Hi, What if my iPhone 6 wont charge past 3%? Is it the battery than?
I saw that you used 1610A3 but in an other video i see people use 1610A2 or 1610A1 ? Why ? Thank you.
good job
Ciao mi daresti il link per acquistare la scheda completa del tristar per iPhone 6s grazie perché non ho attrezzatura per sostituire integrato .
Hi.. Thank you for the nice spot on your Video.. You nearly knocked my socks off... I have a iPhone 6 that I kind of made a small mess on the U1700.. If I send the board to you, How much would I need to have for you when done And, do you accept Paypal ??
Very nice repair!
Thank you! :)
any problem if miss some points?
hello , someone help me iphone 6 battery getting drain even im changing u2 ic and the bottom 30 pins ic but the problem remain same the battery percentage getting darin once the phone i trun off and on before i trun it off it was 60 % and after it trun on it becomes 12% i changed the whole charging area even the crystal 9 pins ic but the problem remain same help me
brother iphone 7 glass IC and iphone 6glass IC is the same IC or deference???
hi sir my i phone 6 unable to detect by i tunes, and no indication of charging, do you think the u2 ic defective, can you give some idea sir? more power to your channel sir.
please connect charger iphone 6 via usb does not work pc flicker logo
Hi can I share this on my page?
Hello! Thanks for this video! Can you tell what is the difference of (1610A3) and (1610A2) chip? in this video you have 1610A3 chip. and in ebay - uk seller sells this (U1700) chip with (1610A2) mark on it. I have iPhone 6 and 6 Plus. Do you have 6S in this video? Thanks :)
I have mixed and matched pretty much all of them (except for the 1608) without noticing any problems. I think there are just newer versions but I'm really not sure what the differences are.
Temp and airflow?
would it be at all posible to completely swap a motherboard? if its the same carrier and storage capacity?
Yes, as long as it is not iCloud activation locked.
Is the U2 ic the same on all this models 6/6+/6S/6S+ please ? Thank you !
No
I tried to replace tristar it on my iPhone 6 and I f*cked it up I blew away all those resistors around the ic do you know where I can buy them from
Your scope itself looks the exact same as mine. As long as you didn't pull a pad, your golden. May need to add memory to the computer, it always helps. Isn't the board a heat sink? What liquid are you using to clean with the tooth brush? Compressed air is dry, you just need to keep a dryer in line and cleaned out regularly(auto supply stores carry inline dryer's). Sorry I post in real time as I watch, I know you it's not live but is to me......
If I had pulled any pads... I would have uploaded the video anyway! LOL
This computer is getting kicked out of production duty pretty soon. There's a way better machine for it already in the shop being used up front. I'll probably try moving things around a bit before spending more money.
These boards are amazing heat sinks and every component, as well as different areas of the board have different thermal properties so a component next to the one you're working on can be dissipating heat and then it doesn't behave like replacing the same IC on a different board. My first iPhone 6 Tristar replacement threw me way off by the extra heat needed compared to a 5C.
I am using 91% ISO - I hear everyone ranting about 99% but that stuff has proven to be a bit tough to get around here and I haven't seen it worth the extra effort. The rest of 91% alcohol is 9% distilled water which does not conduct electricity without dissolved solids and dries totally clean with no residue left over.
hello friend greetings from Colombia your videos are very interesting that it would be good if subtitularas
My iphone 6 recently change u2 ic now i push display and some time iphone turn off and it goes to dead mood.help me😥😥😥
What are your recomendation , if i cant buy a Brandson EC
+johnkor I tried plain distilled water for awhile before I tried Branson EC but it really didn't work for much. A quart of Branson EC lasts a long time. I use 50ml each time I fill the cleaner every few days. All-spec sells quarts for $12. So after shipping it's gonna be $20. I go through maybe a quart per month with the small size of my cleaner. There are probably other cleaning solutions that will work though. Might be hard to beat 12 bucks.
Hi, i watched a lot of your videos, and just wanted to ask you what temp are you using to remove the shields? And one more thing - my iPhone 6 recently stopped charging, and after doing some research, i discovered that U2 (Tristar) could be the problem. So i got 2 new ICs, cleaned everything including the black stuff covering U2, removed U2, cleaned the black stuff underneath U2. Then i ran into a little problem, wasn't sure about the orientation of the IC, searching on google gave me two different orientations, so i decided to try my luck and soldered it the way i thought it should be. The phone turns on, when i connect the charger it says CHARGING, shows the charging symbol, power draw is around 500mA with screen on. As soon as the screen turns of, power draw drops to around 10-20mA... Any idea what could the problem be? Could it be that the U2 IC is bad? Also, IF the orientation of the IC is wrong, i guess the phone wont turn on, or it wouldn't charge, right?
I think your Tristar repair is good if the phone boots. I've seen one other phone doing this and I've replaced dang near everything and it still does it. I no-fixed it back then but now I know the only things I didn't replace were the PMIC & the charging coil on the other side of the PCB. Very weird problem... draws current through USB only when screen is on but still doesn't charge the battery. Weird problem
btw - I would call that a successful Tristar repair.. even if it didn't fix it. Just means it wasn't the problem.
Ok, so i replaced the tristar IC, again, thinking it could be defective, no luck, still does the same thing. Like the phone is getting power from the charger, but the battery isn't. Thinking of replacing tigris IC next. From what i fond on the web, it's also has something to do with charging. What do you think, should i try it, or if you have any other idea/advice, i'm willing to try anything. Oh yeah, one more thing, before i replaced tristar IC, the phone had battery draining issue, now it seems ok, battery only dropped 2% overnight. Oh, and thanks for the reply.
Easy way to clean the pads and remove the underfill is just use a micro pencil and load it with lead solder. Add flux, clean the pads with the solder and the heat will remove the underfill.
You can then just wash it away with alcohol.
thank you! :)
Chris Long sir i have a problem..
1: i took off the chip but im kinda missing 2 pads and 1 component on my board.. is there any other way i can fix it?
2: how do i know if the chip is already attached on the pads itself after heating it up?
Which pads there are a few that are NC (not connected) the components can be scavenged off a donor board.
Add a little flux on the pads then place and hold the chip gently in place. Add heat till flux melts a little. Then remove hot air. Remove tweezers slowly not to move the chip. Then heat with hot air till you see the chip sink down and it'll pull to the pads if you align it correctly.
thanks for Good video 😃what kind off hot air station do u use ?
You're welcome! Thanks for watching :)
That is this station:
www.amazon.com/Aoyue-852A-Digital-Rework-Station/dp/B000HDDXY0
I've never been rich enough to use one of the higher end stations so I really don't know the difference. I've used a couple of cheap ones and some of them are just too cheap. I chose this one because it has a heavy ceramic heating element causing it to change temperature slowly and be much more stable. I had one that was way cheaper but the same brand name. It only had a wrapped wire element at the nozzle that would heat up to the set temperature in the snap of a finger... those are dangerous and unpredictable. There are many on UA-cam that will say you can't use anything less than a $600 station - that's not true at all. This one works very well and works all day long every day. For the price, I could replace it every year if I needed to. No clue what that vacuum pickup tube is useful for other than making noise. I keep it thrown off to the side. LOL
Thanks for the info , fun to see there is good resulat with 120 usd station ;)
+Anders Lindquist I will eventually upgrade it like I did the soldering station I love so much now. But I'm only running the air at 40% and temp at 380 (most of the time) so if I needed more ass, there's still lots of room to turn it up.
It sorta gets under my skin to see people saying you can't use anything cheap because you really can once you get a feel for hot air and PCBs. I'll be upgrading for features other than hot air quality. This one takes me forever to go from 100c to 380c with the push button digital setup. Presets would be nice for saving time. That would be worth it for me. Thanks for asking!
You said it requires a lot of heat, and I've never tried it, how about using a low melt alloy to remove this IC chip? Would it hurt anything? Of course you need to clean it off the board real good before mounting the new chip. Just curious coz"I've never tried on BGA. I was thinking if you're not able to get all those low melt alloy residue off the board you might end up with a weak solder joints.
Lowering the melting point makes it a lot easier putting the new IC on but no way to do it until the old IC is removed. I certainly wouldn't use that low melt stuff because of the weak joints tho.. leaded solder works best.
BTW, you have got to be the neatest with the cleanest soooo organized shop I've ever seen! :) My old lady nag me everyday and said I'm a slob when it comes to keeping my shop tidy. I argued and told her " Honey, actually I'm a neat freak but I just need to get over it and so far am doing a damn good job at it" :)
1610A2 or A3 same work
What brand q-tips do you use? They look better than the MG-Chemicals q-tips.
Those are Dollar General brand q-tips from the cosmetics section. :) They're $1 per bag here. I may switch to something more "professional" one day but for now these are cheap and work really well.
WOW I thought they were special one's for soldering, should have lied n said how much you spend on them! HAAAAAAAAAA!
Sir, how do i know if the 'dot' of the chip is in the right direction? (iphone 6) which way do i need to place the chip, because i dont have the schematic program to see if im doing it right..
On most PDF schematics, there's a red arrow that indicates pin A1. A1 is pin 1 and is the direction the dot will go to.
STS Telecom
oh too bad i dont have PDF schematics programs.. can u tell me which way it has to be placed? or its not the same each iphone/chip?
Hey is it possible that you fix my iPhone 6+ that doesn't get any charge? and how can I contact you privately?
It's best to call our shop or send email

my iphone 6plus battry drain. in this err cud be damage in my fingerprint not working..
now my fingerprint not working
good good good very good
Hello again! Please help I just replaced tristar and when powered on there are only white screen with Apple logo and it stays in Apple logo. What happen if there are no tristar at all, is that same Apple logo then? I'm gonna reflow it again if the balls not melted properly and hope it works. :) or did I destroyed it/Flash drive with too much heat?
Ok. After reflowing it works and charging but screen is flickering at the point where screen is dark (slide to power off) lol
+Inspiraattori I've had to restore them through iTunes before after a Tristar replacement and having issues like that.
I didn't see this comment before my last reply.. A restore is not going to fix the flickering. Sounds like something must have went wrong.
+STS Telecom I was lucky it was just a bad screen in this case.
the 6s does it take the same exact chip? thanks!
I've never had an issue mixing them up. I've used 1610A1, 1610A2, & 1610A3 intermixed in many different iPhone 5c, 5s, & 6/6s.
Can I use iPhone 6 1610A2 u2 ic on iPhone 6s?
Please let me know.
I have never had an issue with it. :)
thank you!
I know it's hard to tell. I have get a few iPhone 6 devices where phone is dropped. No power. I measure vcc. And it's short to ground. What do you think could be the issue? Or how would I go in approaching the solution
When I know a line is shorted, there are many times I wind up putting current into that line at a safe voltage for any component on the same line - and waiting for heat. Usually narrows it down pretty quick. If it's not immediately obvious, the schematics combined with where the heat is helps to tell where the paths to ground are and narrow it down. 1 to 2 volts usually gives me enough current to find the heat source on VCC_MAIN. :)
+STS Telecom I agree. And I have done that. Nothing gets warm to the touch. Comparing voltage drop to a known Good and I see same numbers
Removing the suspected chip then testing, I assume would remove the ground.
Just realized you never said VCC_MAIN, you said vcc. If you're getting the same readings on a known good board that means the area you are testing is good.. it's gotta be something else.
+STS Telecom but I did mean vcc_main. Thanks for the tips
Thank you !
iPhone 6 battery full charge 1% battery so not charging so solution
iPhone 6 battery 1% charging remove off
THANKS
you're welcome! =)
If I send you my phone can you fix it? It is not powering on and Apple is trying to charge me 300 for a replacement phone when i know its something really simple. i just want my phone to turn on so i can at least back up my data to my iTunes. I am willing to pay. Please message me
didn't realise how much heat this chip tool until today. Pulled two pads :(
forced it up thinking it was some underfelt holding it down
Oh man, the iPhone 6 Tristar IC takes crazy amounts of heat. I have no clue what is there that gets rid of heat so fast in that spot but just a few millimeters away and things float the way I would expect. They're tricky not to pull pads because the rubbery coating is holding them down too. You wind up having to pull on them pretty hard even when the solder is melted. Makes it tricky.. I did the same thing not too long ago and had to run jumpers. Hopefully your two pads are on an outside pin.
STS Telecom both outside at least, ran two tiny jumpers using solder brade. Don't think customers know how much work goes into these :S
*first thing im going to do is JERK !* HAHAHAHA killed me i love you man LOL!!!!
Hi
hi thinks for telling as to every 1

This is real videos and thank you dude, you deserve thumbs and subscribe.
Can you pleas tell us Temp and Air Flow presure you use in this case ?
Cheers
I have a iphone 6 and when i dont use it for a few days when it dies it wont turn back on and the battery reads 1.4v i have to jumpstart the battery just to charge it any help ive tried dock connector
