MacBook, water damage, backlight alternative repair solution

[@PHONE-LAPTOP-REPAIR]

this is great job trying not to loose money for new connection. this is a good example to those who don't have the parts like me. i love the job. thanks sorin. i know if he got the part surely he will put in a new one but this is a good example to carry on work without spare parts.

[@rs4016]

Hallo Sorin, the reason, this wire is shielded is simply to make things more complicated. Apple didn´t like if other people fix their stuff.

[@ernieschatz3783]

This is the one true answer!

[@maz.informatique]

Nice done Soren! Today I just brought back my first water damaged device "MacBook Pro 2017". There was no issue with the screen connector but 6 or 7 rusted points on the both sides of the motherboard. My customer first took it to an Apple store and they said it is going to cost about 800€. Of course she refused... 😀😀

Pre check: 1. Laptop comes on with no back-light. 2. Other technician checked and determined water damage. Inspection: 1. Burnt lcd connection Procedure: 1. Clean burnt area 2. Check if there's short to ground; NO shortage 3. Power on and check backlight voltag: no voltage, should be ~30v 4. Before trying to fix anything, give the voltage to the capacitor to see if there's short Adjust power to 30v, 0.17A With the lcd connector, Voltage dropped to 2.5~2.2v, which indicates there is a short; when not connected, no current drop, no voltage drop. Which indicates the short is on the lcd connection cable. 5. Pin 3, 4 are burnt on the cable. Cut out the cable wire, as well as the pins onboard. So when the cable connects to the board it won't touch anything. 6. Solder pin 3,4 together to a jumper wire, because LCD takes 30v, the jumper needs to be able to handle that voltage. 7. And solder to the big capacitor 8. 9. After that, still no backlight. 10. Follow the track back The fuse is burnt. Make a jumper to bridge the fuse. 11. Check the voltage, we have 25v. Repair done

Really enjoy seeing your approach to repair compared to others. Very good.

Hi Sorin, great job, I'd say you're almost a microsurgeon. Thank you for showing your work.

[@johanponin1360]

I've seen microsurgery less subtle than that.

[@ipoy98]

Nice solution Mr Sorin, using only existing "simple" tools and no schematic at all !!!

This helped me out so much, I thought my MAC was done for 😭😭thanks! Liked and subscribed

[@halideyamanuel390]

i always like repairing than replacing, great job

[@computersrepaircotesaint-l7407]

Big Love.. What I want to see is videos that you couldn't repair the device, thats interesting and much more to learn

[@Zolive974]

It's like asking the sun not to shine. Impossible. lol

[@computersrepaircotesaint-l7407]

@@Zolive974 It will be a bid learning. obviously not everything can be fixed even for the best tech

[@Swenser]

Yes. Maybe others can offer solutions too. Please show failures too Sorin

[@pinakbhattacharjee7475]

A nice repair work....but difficult work to jumper a wire but u hv done in a easy way....👌

[@techparistech2659]

Hi Sorin, great job

[@linksrepair2851]

another great lesson from you,sometimes we have to think out of the box great job and keep the videos coming and greetings from norway.

[@yuanho2883]

big problem, great solution. and you make it look so easy.

[@paint32uk]

Thank you so much for doing this video! Mine was slightly different in that the a track and pins had blown off but it pointed me in the right direction!!

[@108Marlin]

Another great video . Thanks Sorin.You make it look so easy

[@grizzli211]

Well done , congrats !

[@Philippe-Philou]

Hello sir, Well done, Thank for you vidéo Sorin

[@vincepirozzi9603]

I would have used a millimeter to determine the current across that fuse and replaced it. I just don't feel comfortable jumping fuses. They are there for a reason.

[@Flavius-Tech]

Ce am ras de siguranta ta :). Mi-am amintit de sigurantele din tabloul electric de pe timpu' lu' Ceasca :)

[@Dr.Leszek]

Proper Wire Calibrated Fuse :D the old school one

[@Lordkj87]

Very clever Sorin :)

[@MrRvdbeek]

You are amazing thank you for the great work 👍🏻👍🏻👍🏻

[@kimspeller6941]

i wonder how many fuses i have in all the cables i have in this house ? lol good work, and no more dodgy than apple not putting air vents in the bottom of their laptops ! :)

[@m2a687]

The shielding on a cable is usually to prevent external interference.

[@electronicsrepairschool]

'usualy', i know. But this is a dc 25v line, not a microphone cable :)

[@hidden_vault]

brilliant

[@jerrymichael9705]

Amazing

[@GregM]

Free OpenBoardView software plus openboard view files and schematics are available on the internet if u are fixing a lot of Macs. There is also a OpenBoardView Flex from Paul Daniels which is $80 that adds additonal features.

[@Frank-Thoresen]

It is all logic for Sorin. Experience beats schematics 😀

[@jeramsadventuretv4905]

Thanks!

[@ilarioschneider2917]

Sir, i think you bypass one or two resistor, wont be too much current in the backlight?

[@ВалентинЧуркин-о8м]

Четкий дядя! hello with Russia

[@santoshmundepi2977]

Hi sir you are amazing job.im bigener in laptop repairing.i wanna ask the question that when press the laptop Power button it's not on.im check the supply in power button it's present I'm checking the voltage in io chip s near components and battery connector or bios pin.they are present.but it's not on.please make a video how to solve this problem.

[@theethicalh3707]

hello sir thanks for the video but i have a question how did you figured out that this 2 wires are used for backlight i didn't get it

[@areuserius328]

Maybe because its the only fault the macbook have...no lights??? Because at the beginning of vid he powers on the laptop and there is sound indicating its ok except for the lights...

[@mariodistefano2973]

Hi Sorin, *SPECTACULAR REPAIR* !!! BUT a bit of perplexity n the event of a "de-ja-vue" or in "come back"... repairing this way, couldn't make your "hand on -again" event more difficult, maybe impossible... is this already happened to you?

[@ancazah5910]

Congratulations for what you do! What nationality you are?

Hello, excuse me, how many volts must have in the pin 3 and 4 ?? Thank you

[@ernieschatz3783]

"I don't think it's a good idea to play" LOL!

[@Sorin_5]

Joke mode on: if I give you many wires, can you make me a computer? I think you can! Respect Sir!

[@zx8401ztv]

Ha ha explode, you are a funny man :-D No it's not dodgy, the connector and cable are knackered, you can only make it better :-D. Louis rossman has said that the fuse has never protected the connector, often it is not blown, so pointless.

[@electronicsrepairschool]

True, fuse is not there to protect the connector, is there to get burned instead of starting a fire by high flow current

[@zx8401ztv]

With all the soft drinks and nasty stuff on most apple pcb's i think it would have problems trying to burn. Unless someone poured petrol .... oooww he he :-D

[@babak.400]

you r amazing.

[@alexandrupatrascu7647]

Buna seara Domnu Sorin. In primul rand vreau sa mentionez ca va urmararesc cu mult drag de ceva timp. Faceti o treaba minunata. Ptr asta va multumesc! Mai invatam si noi de la Dvs. Am si eu o intrebare daca nu deranjez : Am un laptop Lenovo ThinkPad T460s si nu gasesc nici o solutie ptr a reseta BIOS-ul sau parola.. (specific ca si eu lucrez la un service si laptopul este al unui client care a uitat parola). Multumesc mult. O idee m-ar ajuta.

hahah funny vid, great stuff, bruteforce fixing no parts needed

[@justinspiredfallout]

They're not all connected.

[@Gonnzi]

on minute 7:10. i can see image on display with low backlight ?!

[@RespawnRestricted]

The point is simple Apple lmao

[@dost79]

Maybe it was the fuse only at first, as if it doesn't send correct voltage to ahead components they won't work as they should and due to low voltage shortage. Can anyone correct me please, I'm just beginner

[@electronicsrepairschool]

check the video again, we checked for short, line was shorted, thats why the fuse got burned.

[@dost79]

@@electronicsrepairschool agreed but just wondering what if fused have been checked before hand and replace and then see the voltage on display port. And i did watch full video, great job anyway. Would you mind if i ask where about in UK you have shop? Would love to visit you someday, i had small same sort of business in Nottingham. Thanks

[@electronicsrepairschool]

You have to follow some rules on a water dmg jobs, first check the power rails for short and remove the shorts, second - bring up the power's supply. We are based on east London

[@kenben8207]

trash solution but it works : ) ! i think from repair shop people expect other solutions
