lmao honestly need to be a psycho to spend so many hours doing a repair on a 600$ device for only a couple hundred bucks..

@@stevebanning902 A 4090 costs 2k.

@@watchmen22 A broken and used 4090? lmao nah

​@@stevebanning902 But what it's worth after it's fixed? You're saying it's not worth fixing but It's absolutely worth trying to fix it. Especially 4090s with a cracked PCB at that spot which so common.

@@watchmen22 probably about $600 lmao like I said. No one wants to buy a refurbed 2000$ GPU

will do 🙂

​@@northwestrepairthese repairs 99% techs would never even touch. Much respect

complex repairs.... uh huh, on a stiffener rib... no electronics there lol... why you dont see any copper striations..there's no contacts to take the, to.... look in your eide port there's no pin it the side lol its just to pin the card down with the slider that foes over it

@@HarmonRAB-hp4nk what are you talking about??

@@HarmonRAB-hp4nk you obviously missed the line the crack went through

What about the 75w from the pcie slot?

@@Jasontvnd9 on the big cards the major components usually run fully off the cable. The slot power may be used for stuff like fans, LEDs, possibly audio controllers, HDMI/DP encoders etc. You can't just combine the power from the slot with the power from the cable, and dynamically switching based on load is very complicated, so it's easier to just run everything off the cable. Lower end cards might run the core off the cable, but the memory off the slot, to spread the load a little more and not require too many extra connectors.

theres no pins on that tab, its the lockdown tab... great job fooling everyone but a pctech of 25_ years :-)

@@HarmonRAB-hp4nk Lol. Good one. 25 minutes?

Also most cards unless youre talking a modem or some Wi-Fi adapter tend to have dedicated power adapters so as to assure the device is powered correctly regardless of the load on the board or cpu. Kind of a cover our asses clause built in to the component. At least since pcb slots have become more versatile in the type of hardware they can accommodate. However we see what happens when your ass covering design dept gets complacent

its the card retention tab.. no electronics in it lol

@@HarmonRAB-hp4nk No electronic components, but on multi-layer board this kind of crack creates huge problem, and that is why the wires are essential he put in. And the way he laid them is essential too. PCI-E protocol is very strict on timing. Basically all the connections in the PCI-E slot must be exactly the same length, otherwise the protocol doesn't work. Latency isn't a problem, and this is why something like riser card can work. One could say that yes, there are no electronics in that tab, but there are signals running in the copper layers inside that tab. The phase difference the crack created in this particular card propably messed up relative timing of the signals, so some signals took longer to go around that crack made the card non-functional.

They won't fix it cause the cost will be at least $500

Exactly... northbridge replacing only shorted cap and mosfets

Wrong. Properly treated epoxy will harden, not soften when heated. Final hardness after initial curing is achieved by curing the epoxy in 60-100 celsius, but after the baking epoxy can handle higher temperatures. Of course there are many different formulations for different use cases that have bit different chemistry going on, but the process is the same for all epoxies. Even PCB has epoxy as matrix, and this guy on the video bakes these boards for extended time in 200 celsius and even more when soldering, and PCB can handle it just fine.

I didn't learn shit. Just admiring his skills is rewarding enough.

Just like watching "slow TV". Nice n' relaxing

I recently repaired a Switch I got off ebay for 65 bucks. I wasn't confident at first, especially with doing trace wires. But it's working now and man, it does feel awesome the first moment you power it up and it's working perfectly 😄

@@kulilin3104 that feeling alone is worth it, plus saving money doesn’t hurt too 🤙🏻 good job bro!

Might be OK with a bracket.
