Asus J751 ROG Gaming Laptop Repair - Finding Short Circuit without Voltage Injection

[@richardhead8264]

*1:40* _That was the silica gel desiccant that the customer mentioned in their note._ 👍

[@GeminiSynns]

Forgetting hes under a microscope I swore it was an orbie

[@shmuelblitz2069]

6:31 "Okay, done. Those caps are soldered down perfectly" :) You made my laugh out loud.

[@tejmar]

I'd love to see everything that's now in the 9th dimension!

[@davebollinger8863]

One way ticket. Lol

[@charlesa8501]

A bunch of 10mm sockets

[@SmoneUdntKno]

Lots of screws that fall of work benches

[@beto12345]

Mmmm that bubble looked like a silica gel 🤔. Those accidents with liquid are difficult ones, clean or a mess. Nice job as always.

[@additivealex4566]

I thought the same, silica from a dessicant pack. Or perhaps bubble tea was spilled and that's a dried out bubble. 😅

[@joshuabest100]

I hate when I spill laptop on laptop 😂 great video as always

[@melstead7937]

That smile @ 15.46 sys it all! You continue to amaze. Awesome.

Always surprise me how fast do you find the fail component... Amazing!!! like always... Another "EASY FIX"

Yeah Easy fix when you know how to find it lol. Amazing as always though

These are great videos to watch if you don’t do component level troubleshooting on a regular basis. Excellent work!!!

[@davidefogagnolo]

it is somehow frustrating that most of the times the repair is incredibly simple (not counting the troubleshooting skills), it is such a shame that countless simple to fix devices are thrown away

[@mondomongs481]

agreed. most of them can be fix.

[@drftr6073]

this is already replacing subcomponent territory. most fixes don't require replacement at all.

[@MirceaD28]

True. I have 1 Samsung J710 motherboard that I cant find the problem ... 2 shorted caps..

[@supupandaway8138]

Not counting the troubleshooting skills its also knowing to heat the board up from the bottom so that cap doesn’t shoot your eye out or what if one of those caps he removed entered the 7th dimension you have to know how to figure out what goes back there and not that its just a cap but what package and what capacitance goes back and I’m just getting started take that board heat it up then bump those parts and mix them up and not have a schematic and good luck getting it back together caps change resistance tolerances also when they are in circuit and vice verse I’m sure you are getting the picture by now

[@kevintanaka4351]

Thanks, Alex! Needed a good laugh today. Referring to "both caps are soldered on perfectly".

God of repair... 😍😍Love form India 🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳

[@burnedik]

Hi Alex.. can U show us how to apply heat from the bottom of the board during removing/installing components? Please advise what is recommended temp too.. ty

[@JackCsepp]

As always you are top of the line with your board skills, Thank you for sharing

[@NatureHub01]

Just curious if use ultrasonic cleaners at all?

[@kyleadonis5451]

Laptop spilled on the laptop = Holiday mode still enabled

[@iyadshwiky6712]

very good work as usual i am so happy to see this repair with only use a multi meter thanks again

[@tawnyb83]

Great work as usual. Question, the thermal cam that is your website, is it comparable to the Flir that you use as far as pinpointing a heatspot?

[@souadjbour30]

Excellent job.even if the mosphet is (hidden),our great man found it easily.thank you ALEX.

[@northfixtz]

Troubleshooting techniques of your is amaizing until you realize its matter of experience on working on different devices

[@mufeedco]

I think putting Thermal Adhesive Tape on those MOSFET is better than White Thermal Grease that already there. Great video as always!

[@TomsTechRepair]

Good process of elimination. There was me thinking it was the chip that was water damaged. Need to get a better wite brush like yours, mine is just about done.

[@SAZodia]

Good job as always, That is a great little laptop, I have the same model (now with the 980M because I blew up the original mobo LOL).

Merry Christmas Alex, waiting for more videos!!!

[@alotl1kevegas860]

Have learned alot watching your videos. Would of never knew that about the factory Flux. I would of just figured that it was excess from the factory.

[@silent9pc]

Most manufacturers leave the no-clean flux on them

[@OShackHennessy]

I think I heard almost all the great one-liners in this video

[@VK92KL]

Man when he soldered those two caps together and said done I almost pissed myself. That was funny as hell 🤣

[@lucymc0191]

great fix alex good old simple diagnostics pleasure to watch ..... thermal cam and voltage injection into the 9th dimention on this fix ....

[@marshall1780]

Hi awesome job I'm a big fan I have a question What temperature do you use for thick boards like laptops or PS4?

[@silent9pc]

650 or 700 F should handle a PS4 board no problem, depending on how well your iron compensates heat dispersion on ground planes. Having hot air or a board heater greatly helps though.

[@kevinbaker2470]

Hey boss, when heating from underneath the board, what temp do you set your hot air to? 400 still?, id like to try that technique, im self taught, and typically if im doing a repair real close to an aluminum cap, I cover it with some modeling clay /play doh, and put a more concentrated tip on. Thanks again, you shoukd start a patreon, im gonna order a bunch of stuff i dont need from your site, because you've taught me so much

[@stephanebegue3124]

Another great video. But what about for a video, for a laptop, powered but not turning on, the fan is not spinning. Or powered on, the fan spins, but does not turn on.

[@limebulls]

How do you know what's the concrete "type" of the replacement mosfet? Do you have a mosfet collection?

[@rayhastings2934]

I've watched many of your videos, when you say apply heat from the bottom are you just hanging the board over the edge of the table?

[@walimo6810]

BTW, the bubble at 1:37 is part of the dessicant the customer mentioned using...

[@puffinpuffinov8471]

Why dont you use capton tape to avoid heat on capacitor?

Did you hold your probes with your eyeballs to do that visual inspection?

[@Vo0d0o2009]

if not work plz check one of these tiny filters where the dark soot was , i suspect a blown filter in this area and it is probably its soot

[@Folk_var]

What is the white stuff you pealed back off the mosfet and applied it again at the end? Is that thermal paste?

[@marv4895]

hey love your videos. just im a bit sad i cant see the measurements results

[@Riicky.Allves]

"OK, done. Those caps are soldered down perfectly." 🤣🤣🤣🤣🤣🤣🤣🤣🤣

[@朱建宇-e7k]

Can u introduce the soldering gun u use? The plier type Thx

[@djr3485]

Putting that ice cream back on the mosfets… LOL

[@Roctrin]

2:45 why are the traces in a squiggle pattern? Does that have a function?

[@LudwigvanBeethoven2]

Yes. Length of some traces must be matched for high speed connections for example between CPU and RAM so that bits arrive at the correct time.

[@re-fix9678]

repair skills👍👍👍👍

[@nauticalpirate]

What i think is, when the Laptop is working then the tea was spilled, the water goes through then made a connection with the components to cause short circuit right?

[@technologylover5976]

You never did a video on black pasted ic. Plz make a video so that we learn from you more.

[@KogiSyl]

For me it's all magic. Every time I'm trying to fix some motherboard, I'm trying all different things and it never works. I know electronics, workings of various devices, but I still can't seem to be able to fix a single motherboard.

That weird bubble was no doubt a piece of the silica desiccant that he mentioned in the note.

[@Daddysaurusrex]

Ok I'm not sure if I have a power port problem. My G751J will power maybe one sec then turn off no screen. Battery light will blink then go solid after a few moments. I'm getting continuity though out the board. Any suggestions as to approach this repair?

Hi Alex, I have suspicious problem with my gamer laptop board. After two inrush limiter mosfet my dmm reads 12-13 ohms, and the Vcore pad shorted to ground (1.2 ohm), but after I injected voltage, (1V, 2A, 3A before CPU) nothing gets hot. Do you have any idea what's gone wrong? Thanks for answering.

What is that white "ectoplasm" stuff? I've seen it before on other fixes done here. I can only surmise that "Slimer" has been haunting this lap top. An entity that causes computer problems. Might need to call in the Ghost Busters!!!! Hey, that "bubble" was ghost egg!!!!

[@brianredmond4919]

What is that white stuff and what for ?.

[@alialshams1043]

nice Vedio ☮️👍

[@robertpage2023]

There are times when you are diagnosing a board but and you do a random look and test of components but don't begin with the thermal camera which to me, would be the obvious first step after a look for damaged components. Also, What is that white stuff!!!??? I must know, the suspense is killing me!!! Tell me please!!!! OH, am I being too demanding? Just kidding. After watching to the end I see that you were just showing us that you could find the problem without going thermal. That was a very good and surprising ending. And I 'm suspecting that that white stuff is some kind of thermal paste? maybe? as I saw you trying to put some back on the mosfets.

[@dreamcat04]

1:40 ot is udes to dry stuff since it sucks up much liquid althoughit OS very tiny
