A million dollar video, This tells you what he has to go through and nothing left out. We all take a beating sometimes and just have to learn to walk away. Jason you are one of a kind and honest person that many should learn from. Thank you for all you do my friend and God Bless.

[@imranosman210]

Jason, every video you do is CERTAINLY beneficial. I respect your patience and honesty man, failed repairs also have so much value when they come from the worlds top techs as urself. Hats of to you🎩

[@zhairegregory8546]

I learned more and more each time I watch a video. Keep up the good work, and I need a repair ASAP

[@EdgarYoReparo]

What about if you press down the CPU?? Thanks for everything Jason. Check my email.

[@newvoyeur]

Didn't try changing out the coil. Wire insulation melted - possibly caused partial intermittent short affected by heat

[@TheXmenForce]

Jason, Sometimes Bad Coils do That, screen comes on,but after a few minutes when coil gets hot,it fails and you loose image.

[@nikosbiologytsiouplis1895]

is it possible if you remove the double image filter to get a different diode reading on the cpu side? if i where you i would try it as my last resort.

[@ustadgaming6804]

When i remove capacitor c3936 and c3930 i got the image 😍But image is some multicolour and lining and the half lights of lcd are blinking and half are off 😢 I’ll definitely wait for you reply 🎉❤

[@Bandseli]

Hi Jason! I have a similar problem on that DWI_PMGR_TO_BACKLIGHT_CLK have no image and backlight too It goes to cpu reading is on the cpu side 0.45 should be 0.345 Any ideas?

[@donnierobertson3088]

Nice job

[@BrokebackBob]

Think different! Think crap!

[@Mr.iphonepen]

iphone 7 touch id connecter strip cut plez help

[@dmtech3036]

hi jason sir i have same issue for 7 plus water damage when i powe on display ic getting hot i changed but still same problem no image no light 😇

[@superboychannel4797]

what model microscoop ?

[@singhkarnvir]

I think you should try to remove coil once and again check diode mode readings on pad of coil which directly comes from cpu.... i know its kind a joke but should give a try once ... i have solved same type of fault in samsung once ... thats why giving you advice.

[@singhkarnvir]

@Nikhil RaajeMaankar Faridkot

[@AsadKhan-tk6xk]

i want to watch samsung repairing vedios any one give me a link to watch such a great repairing vedios thanx

[@techroom8764]

Good

[@maxsnts]

Its the coil, its always the coil... oh wait...

[@shipondas8224]

I'm form Bangladesh

[@Haithamm88]

Submit my translate to you buddy ill work on your whole videos when i have time cheers.

[@electrosound4595]

So finally I phone 7 series is not good due to the cpu failures.

[@crazyboombayblahblahblah2869]

Electro Sound not only cpu issues bro..ive encounter a lot of issues with audio ic😞

[@yousoufabdullah8688]

Plzz u can rapier my I phn 7 😞😞😞

[@kinetic4644]

Thanks, It would be great if you could do it in Spanish.

[@steveng5503]

Yeah! I’ve got an iP7 here with exactly the same symptoms. I still have it after the owner donated it for parts. I’ve kept it complete. Turns out someone at a house party put it in a microwave oven for a small period of time as a drunken joke. It boots and operates fine, just no image which is intermittent. The logic board has an internal short under the one of the coils and has been so hot it cooked the solider. I’m just wondering in your case if the power button lines have been effected in the same manner? Maybe a grounding issue with other internal logic board line breaks? I guess the coils would act as antennas when being cooked in a microwave? Who knows what other damage exists. As always Jason a great video from you my friend. Keep them coming? As always a BIG 👍 from me!

[@techroom8764]

Good

[@zx8401ztv]

Dam, that is odd, i think the pcb damage was likely playing with you :-(. That data line could be too close and getting carbon shorted, also depending on the pressure used on the pcb at the time of testing. The old screen sounds like it has a semi damaged data line, with a full amplitude of signal it would likely work. All guessing on my part lol. You are still the king of phone repair, as far as im concerned :-D :-D

[@EPiCxPS3]

Good logic, he should remove the coil and dig underneath it, it's possible with all the heat caused by VDD mains short that the 90_MIPI_AP_TO_LCM_DATA1_P dataline is now half shorted to ground from underneath, especially if it doesnt work during boot(high current) but works more normally during idle(lower current) the short to your data line may only block the display when your current is high enough, this could also just be the CPU but it's worth the shot perhaps.

[@SidneyCritic]

No experience and totally guessing, but maybe it is a liquid short that dried up and became a partial short, ie, a delamination with liquid between the PCB layers.

[@aqib2000]

Bro rehot pmic 😁

[@asrarhassan]

Another good realistic rabbit hole video. Keep em coming... Good Job.

[@Dutch_off_grid_homesteading]

heya replacing the cpu is a lot of difficult work

[@olamilekanadedeji559]

I am guessing cold solder joint I have similar issue here When I apply pressure on cpu Display comes

[@gabrielokocha7271]

Pls Jason what's the zxw short cut you used to look up l3903 in this video at exactly 11:48 of the video

[@Swenser]

maybe throw some high heat over the cpu. see what happens. its stuffed anyway, so no harm in going aggressive

[@suidiquenorgy164]

Thanks for the information and nice work, it really helps a lot of people

[@angiev7874]

That shirt tho! 👍🏼

[@habibhpnarayanganj]

hello

[@Sayam_Pranto]

You can unlock apple id lose mood phone

[@niyigabavictoir525]

Thx a lot 👍👍👍👍👍👍

[@An.D]

sounds like some kind of mosfet in the cpu thats getting stuck, great video Jason 👍

[@cormacpyper]

Nice video thx I once had a sony with no image and first thing i do is test the image and backlight fuse they seemed to be ok ... lol after wasting a hour looking elsewhere i tested again and the image fuse was open circuit lol it seems i had my probes maybe touching the ground shield next to the fuse when i tested first time :D Doh!

[@veggingout5092]

Keep the videos coming, I look forwards to them. Interesting random behaviour.

[@jwjwjw101]

I had the same issue on an iPhone SE rear camera connector. One pin would read 0.071 in diode mode (I think it was the pp1v8 line) so the camera would not work. When I went into the camera app and would press the switch camera button a few times it would all of a sudden start working... I switched 2 caps and a filter on that line from a known good board and saw no difference. Concluded that it must be a CPU short. This video was helpful Jason!

[@alienencounters5710]

i miss mr jason so much coz everytime i sleep i watch always always her videos and i can;t sleep if i miss this........so good man!!!

[@Spector_NS5_RD]

Doesn't that suck? When you go hunting for a shorted line, looking to bypass it with a jumper, only to find out the other end is under SOC/CPU? Which is most of the time with data lines.

[@philipalegren7172]

Hi, i have an issue with an iPhone 8 that is overheating to the point of hurting you fingers when battery is plugged in(Mind you the battery is brand new), it seems to come from the middle of the board Nand/charge IC maybe i have no clue, do you have any pointers to where i should look? i am thinking of leaving it to a shop soon so they can figure it out because i dont have the equipment to evaluate the issue but maybe i can give them some pointers so it doesn't get so god damn expensive with them searching for fault haha :) Best Regards

[@slimfaidy]

good video , thanks for your videos that teaches us a lot

[@michaelmelech842]

Had a similar case about the same phone no image, I think it’s a cpu related problem. Would it help if I reball the cpu ??

[@aqib2000]

It's a semi conductor which your multimeter probes have activated..

[@youbaaskay994]

أشكر ك أستاذ من المعلومات.

[@juancordoba8759]

q buen video maestro, bendiciones. tengo un problema y es aq no se ingles y el traductor de you se queda atrazado. jjajajajajajajajaaj

[@Starsurfer83]

RE-HOT CPU Bro :-) Greetings from Berlin - Germany

[@cardiaktv949]

My phone has the same problem, heat the board up abit than try it will show image

[@justtavi5354]

Will changing the cpu fix the problem?

[@starlovervii9721]

I like the way you explain it.. thanks for video

[@ArthurTugwell]

What’s the name of that green mask stuff you use?

[@alibey8259]

what is lcd size??

[@chauffeurmarco]

Green flux now?

[@sagarbharatsolanki7452]

Very nice Sar

[@andreg953]

Jason, Your work is always on the honest side ! 😉👌

[@mohak7269]

Thank you for lessons Jason

[@wjose68]

hello, thanks for your videos, they are very interesting, I'm learning so many things, I'm not very good at electronics, I would like to ask you a question, I had never used a hot air station before, I've done a bit of practice on some cards, but I have a mysterious problem with an iPhone 6, it has jumped a capacitor C200 that caused the black screen (I think), I should solder, I say I should because I have many days I try but I can not pay it, because any temperature and ventilation of the hot air station the pond does not melt, I can not understand why, can you help me? thank you

[@artman102]

Add low temperature solder

[@itisyewolf]

i didn't see this video yet but i wonder if you said RE-HOT CPU

[@ststele]

Some of these boards I would like to RE-HOT CPU just to get revenge for trolling me.

[@itisyewolf]

@@ststele GG 😂

[@adnaniqbal8537]

I have see this issue when iPhone backlight driver ic is bad, you can take measurement around backlight driver ic and change it

[@zeroskill990]

If ypu listened the phone HAD a backlight

[@3113ym]

Have you made mistake by repairing phone and paying back the costumer ?

[@ststele]

In the beginning of iPhone 6+ touch failures, I replaced 2 phones. One was my fault and the other was not my fault. I kick myself in the ass over both of them because the one that was my fault, I later learned how to fix and the one that wasn't my fault, I later learned was not my fault.

[@dareenyousef2182]

Hi Thank you for your amazing videos, I have a question , where do you get iphone powerlines you know the probes that you connect to your dc power supply and that connects directly to the iphone logic board

[@ststele]

I got mine from unionrepair.com and ipadrehab.ecwid.com or www.mendonipadrehab.com/supply-store is their old site.. I'm not sure which one would be best.

[@dareenyousef2182]

STS Telecom thanks boss I appreciate it

[@mrbigb12]

How much are you charging on average for a repair?

[@ststele]

A rough guess would be around $125. Our range for iPhone 5 through 7+ is $95 to $150.

[@gerardodominguez7567]

Hello!! Where do you buy that green liquid you use to seal? Thank you.

[@dmtech3036]

bro called uv curable solder easily available on mobile spare parts shop and you need also uv light

[@ststele]

Yes, green UV mask indeed. It's very runny but cures quickly under UV light

[@artantrepca9933]

Sir , i replaced a iphone SE u2 ic , but when i plug the cable just for the first time it shows charging sign , when i take the cable out and try to put it again to charge it doesnt show nothing ,no charging sign , no battery increase. Im 100% sure thst u2 is connected 100% ok. Can u give me a little thought pls, im on a big pressure from costumer. TY
