Thanks. I enjoy your video's. My son and I have been fixing electronics for friends and family for a long time. Mostly broken connectors or screen replacements. Since I have been watching your videos we have purchased a hot air station, dc bench power supply, better soldering iron and microscope. We have fixed a lot of items that we couldn't figure out in the past. I usually start my day looking for one of your videos and watch it while I have my coffee. Thanks for all the effort you put into your work and videos. Leo

[@simontuti1]

Thank you for the extra effort you put into making content for KZbin, it is both entertaining and educational!

[@franchesco6797]

The owner of the card must have been sweating bullets! So glad that you were able to fix it, you made the owner's day for sure. Great video and, as always, great fix. 😎

[@noname-oe9jy]

I know he's got a back order of GPU's. I wonder how long this one has been waiting.

[@franchesco6797]

@@noname-oe9jy I forgot about that! Alex didn't mention it was expedited, so I assume the owner has been waiting for a while

4:30 Heat from a current sense resistor is likely because the resistor is between the short and the voltage injection site in the circuit. Inject voltage after that resistor and a new point will heat up.

[@pick_pick_pick]

You sound like a pilot speaking from the cockpit, I truly enjoyed your content. :)

[@MJPilote]

Amazing video as always. Very pleasant to watch and every time interesting repairs! No unnecessary rambling on about what you had for lunch or something like that like many other channels do. And the genuine joy of the work, you really get a kick out of successful repair. Please do a video about the hot air stations. Greets from Finland!

[@davecollins7600]

Love your video's! That cheap microphone sounded surprisingly good. It only had a small "lisp" but otherwise great sound. Best repair content I ever seen!

Much more entertaining than LinusTech Tips recent Video of GPU repair

[@ejeckk]

IKR? LTT's repair was HORRIBLE. Linus has a huge team of guys and it seemed like they barely knew what they were doing. It's just my man here and Big Boss and they do a FAR better and more interesting job than LTT. I'm not crapping on LTT. I like those guys, but their lack of skill in GPU repair was obvious. LTT made me laugh when they brought up Linus' oven reflow method video. The exact same video that Louis Rossmann took Linus to task on years ago prompting Linus to go to New York and visit Louis when Louis was at his old shop. I think Linus should invite Northridgefix to his show.

[@alantorrance6153]

Your replacement (temporary?) headset has a good microphone. You sound absolutely fine through it.

[@superconductives88]

One of the best repair vids ever, thanks I really enjoyed it!! Repairs that require you to be the sleuth are the best type in my view.

[@nicoruizmza]

Awasome as always!!! Every time I learn something new. Side: Fix your own mic cable and post it just for fun?

[@RedRaccoon69]

wish i could give extra thumbs up everytime you fix an expensive item like this! good job!!

[@sk22ng]

Awesome. The "cheap" headset worked just fine, Alex. Viewers like me are into the story and after a minute or two didn't pay attention to it.

[@Darren777Au]

Nice work. Sounds like you may have frayed the wire when you stood up, hence the noise. I'm sure you can fix. ;)

[@knw257]

The faulty chip was a Texas Instruments CSD95481RWJ Smart Power Stage, which is an integrated driver and MOSFET. The replacement appears to be an ON Semiconductor NCP303150 Smart Power Stage. The have the same board footprint, but not the exact same pinout. I'm curious how you knew the replacement chip was compatible with this application.

[@bkaczy]

That is the experience and knowledge of Mr Alex! All you have to do is compare datasheets...

[@knw257]

@@bkaczy I did compare the data sheets, which is how I knew the pinouts we're slightly different. I'm not great at reading data sheets beyond some basic info, though, so there probably something I missed

[@bkaczy]

@@knw257 Yes, the pinout is not the same, but the size is identical, and important pins are equal placed. So there is a moment when electronic knowledge is helpful

[@siau9049]

Prolly he got experienced enough by working on so much gpu, and found on that different brand use that different mosfet chip on same gen gpu with same PCB layout

[@sarkissoum]

good job man wish we have a guy like your in france

[@goobiie]

This is really educational...I love learning this kind of repair....any training course available?

[@Waltkat]

Outstanding video. Doubly so because I have the EXACT same GPU card with the EXACT same problem. What are the chances of that! The only difference is, the trouble spot is a short indicated at coil L249 rather than L250 as in this video. The capacitor associated with this coil is also showing a short. The MOSFet on mine is a NCP 303151 rather than the 303150 here. I was going to do the repair myself because I'm experienced in electronics and repair, but my experience and tools are for vacuum tube equipment and through mount electronics. Yes, I'm old. Lol. I figured out that me buying a hot air station, thermo camera, and other associated supplies needed to repair surface mount electronics at my age and eyesight capabilities just wasn't worth it. So I sent in a service quote request to these guys at Northridge so we'll see how much it's going to cost me for the repair this beast.

[@Mladjasmilic]

I have an idea for finding shorts: You put magnetic suspension for looking at magnetic fields near pcb and inject current. It should trace the current path.

[@musthaqmohammed8098]

Really good idea thanks for Northbridfix

[@melvinvandenberg8297]

FYI at 13:43 you can see the new chip bubble up from the heat. This new chip may not live long. Surprised it even works. It's hard to solder these mosfets on such a thick board with pads that don't have any thermal relief.

[@victorpaul80]

damn was just wondering when is Northridgefix's next GPU repair vid.

[@BurninSven1]

Thanks for sharing a big thumbs up from Sweden

[@BordogoyBokzVlogsofficial]

Always watching sir!good job!

[@Folk_var]

Great stuff. Would like to see more GPU repairs.

[@ShR33k]

That mosfet you changed looks very different - far more complex to anything I've seen in previous videos. Is that specially for GPU's or is that 2 packages in one or something? Great work. It shows the benefit of the infrared camera - a real time saver. Trying to find that manually would of been more time consuming and difficult.

[@SiegeX1]

It was still a 3 terminal device, just in a different IC package. If you look at the pins you’ll see that there are three groups connected together, and a copper pour on the bottom to connect it to the ground plane for heat dissipation. The larger package allows more heat dissipation and thus a FET that can handle more current going through it.

[@Mueller3D]

It's a DrMOS, which combines two mosfets and a driver into one package.

[@محمدابراهيم-و8ذ]

Thanks, i enjoy watching your videos, and i have 2 question, ones what is the model of the thermal cam that you use, and i see some osilascopes on the shelf next to you , for what do you use it for?

[@geofyre]

Yes please do a video on hot air stations!

[@Trught]

13:44 is that mosfet bulged from over-heat?

[@cybercat1531]

Something strange happened there for sure. I've usually only seen this "popcorning" happen with PCBs when there is moisture trapped in them that expands to steam from heating. Something similar may have happened with this MOSFET/powerstage due to gasses trapped in the package material. But clearly it seems to not have affected the device functionally.

[@72pinkush]

Hello sir. There is a trend about undervolting graphics cards. Feeding them less volts than manufacturers intented seemingly makes them perform the same, use less power and create less heat. Do you think this could create any issues?

[@skullkrusher6753]

I'll wait for answers too 🙏

[@Hackimaster]

More often than not, those factory voltage settings are to ensure stability across all made Graphics Cards from a manufacturer. Undervolting only reduces the amount of core voltage which goes to the main processing chip on the graphics card. On paper, this can cause stability issues but should not cause any damage to the components on the PCB of the graphics card. Feeding too little voltage to the core should generally speaking not be able to cause issues which kills a GPU.

[@seblaf521]

hi, dont worry it's 100% safe, the term undervolted is a bit miss represented here tho. if I remember correctly, the real term for what you say is called clock stretching which is setting the highest clock possible at a desired voltage. Your cpu/gpu is already running at those range of voltage from factory but most likely higher than what you want/need, since they are mass producted they're applying more voltage than they need just so that 99.9% of them work without issue out of factory because all silicone chip are created different with their own imperfection and it would be costly for them to test each individual chip.

[@techbuildspcs]

No. It's simply better silicon or a better bin. Keep them cool and they will last even longer than usual.

[@hieshaamvanniekerk3445]

that heat spot was hiding very well lol

[@marsvandeplaneet7786]

Now you sound and look like a pilot! 'Permision to land, please.'

[@Kraaketaer]

At 13:45, when soldering on the new mosfet, are my eyes tricking me, or is the heat making the top layer of the mosfet packaging blister up for a brief second? That must be immensely hot - can't be much headroom before components are damaged at those temperatures, right?

[@syberpunk]

You’re right, it’s better seen at 13:44. This is too hot.

[@mikegaming4924]

13:43 the replacement chip popcorned (which means it overheated during hot air soldering and deformed)

[@samuelvincent2007]

I'm curious to know what kind of price a customer pays for these services. I hear you say sometimes that there's a minimum 60 or 65$ fee (fix or no fix), but how is the total price calculated (excluding shipping). What is the average cost of a gpu repair ? Bought a broken 980ti for 20$ recently and if I can have someone fix it for around 80$, I could make decent profit reselling it.

[@zacharytaylor8523]

I have to question for a card that isn't even 3 years old where is Asus in doing warranty RMA? I can probably haphazard a guess that the person bought it from a scalper with no receipt, but it still really bugs me to see such young cards (of which all should still be under warranty) having to be sent off for repair and the owner having to pay for repairing something that is purely out of their control and what should be covered.
