this is just ... amazing ... i don't understand electronics , but i love watching impressive battles to bring life to electronic devices as you do ... thank you
If Kris and Louis got together there would be some type of event horizon effect. Amazing work Sir, the knowledge and your skills are something to behold. Thank you for sharing your time with us.
By far one of your best video Kris .Very detail diagnosis ,shows how knowledgeable you are and also a good teacher.Thanks One quick question .The pre heating of the card before soldering is 150degrees Fahrenheit ,correct.
Andere hätten wohl schon lange aufgegeben, echt interessant wie von der Pike auf nach dem Fehler gesucht wurde. Schön zu sehen das viele Karten nicht einfach weggeschmissen werden sondern auch repariert werden. Liegt wohl aber auch an den Preisen mittlerweile. Ich schaue die Videos gerne, macht echt Spaß. Auch wenn ich bei dem Kram meisten nur Bahnhof verstehe. Doch so etwas lernt man nebenbei schon. Danke für dass teilen deines Wissens!
The schematics and board views are great. I tried the site you mentioned to get them but could not figure it out!!!!!! Some of us are not as good as you 😄. Thanks for the videos. Make them looooooong!
Man, that's some electronic detective work right there! Very interestng to look at and follow, please keep posting such investigatory videos in the future
Great Fix. Believe it or not I had the same fault years back on a r9 280. Even the chip was U100 on the board view! SN74LVC Buffer gate. One to keep an eye out for on AMD cards.
Videocard repair seems to be one of the more difficult types of electronic repair work. However, at least the difficulty generally doesn't have anything to do with the companies deliberately making them difficult or impossible to repair, or making it impossible to find replacement parts. It's just that it can be hard to diagnose the actual problem, it requires a lot of knowledge and skill, it can take a lot of work to do the actual repair work, and the replacement parts can be a bit expensive too. Given how expensive graphics cards have become, it stands to reason that repair is becoming more worthwhile. It's nice to know that a dead card is likely still fixable.
Yeah, but "hard to diagnose" part is to a significant degree caused by manufacturers themselves - e.g. good luck finding 1) PCB schematics 2) PWM controller firmware and actual settings. Word is MPS/NVidia encrypt/password protect PWM controllers on their cards 3) unencrypted BIOS So while I agree that repairing of graphics cards is financially viable, it takes a lot of very peculiar knowledge, a lot of extra effort, and some not-so-readily-obtainalbe bits and pieces to even diagnose. And some VERY expensive and specific equipment, like the other guy said
You are teaching us well. Could you tell us how you look at a board and can distinguish " THIS VRM POWERS THE MEMORY, THIS ONE POWERS THE CORE, THIS ONE POWERS............... AND THE RESISTANCE ON THIS ONE SHOULD BE ..... AND THIS ONE POWERS ...... AND THE RESISTANCE SHOULD BE......" Thanks for the information you are showing us. I tried to get the schematics again with no luck! Thanks again. Stay well and Safe. (I am trying to work on 3 109-C38637-00 Sapphire HD 7950 Boards with hot cpu and black screen)
Great Tutorial.. Can you please tell me where I can find the schematics for a ASRock Phantom Gaming 6700XT 12GB D One of the 2 small smd's near the pcie ribbon connector back side is missing , trying to find that value any help would be awesome
Do you ever fix consoles? What I mean is if a customer is having issues with their Xbox Series X. Let's say every time you turn start a game the screen turns into a random solid color. Would you attempt the GPU fix or tell them to go call Microsoft? For reference- I play everything across all platforms, genres, and generations of gaming. This includes PC gaming as well. Both our launch Xbox Series X and PS5 *physical are running fine.
I have 5 test setups. You can use every MB, UEFI bios and integrated graphics are important. You can also use laptop external graphics adapter, i have never tried it.
I wish you would tell us how you know that "THIS ONE POWERS THE MEMORY CHIPS AND SHOULD BE -------- RESISTANCE AND THIS ONE IS ------- AND POWERS THAT WITH RESISTANCE OF---" You could show it in the video which would make it more clear. Thanks for the video.
hello I've been watching your videos for some time your work is amazing, if you can help me I would like to have an rx 6800 xt and my first time with the rx 6000 . I tested the voltage and realized that the coil I think should be 1.8v is 1v as I don't have access to the boardview I did what I thought I should remove the IC and put another one but it's the same VIN is 12v, VVC 5v, EN 0 .11 mv. I'm Brazilian can you help me
Hello @KrisFix-Germany. I own a RX6700XT Challanger and i had problems with temps al the time until i changed the termal pads and everything went great good themps and stable but then i've got alot of crashes even tho the gpu was in the 62c max under load and decide to open it up again but this time i've got the backplate out also and saw a cap or resistor that is side up soldered literaly behind the gpu chip. could this be a problem do i need to fix that or is like that from factory? my knowledge tells me to fix that but this gpu was brand new with stickers and everything. please let me know what you think. Much respect for what you do
I'm from Brazil and I also repair video cards, I have an identical RX6700xt to repair, could you share with me the schematic of this card? I can pay for it if that's the case, I have her boarviwer but I need the schematic too.
Hi, i have a 6700xt that give no image, all voltage ok, only weird thing i found is that REFCLK+ is in short (it was suppose to be 0.8 with the diode test like your video show). this card is dead? i ask because REFCLK+ go directly the GPU core... Thanks in advance.
I have a Question I have 1 Vega 56 with Artefacting problem is it possible to repair it? Please reply if yes how much it will cost to repair.? Hope to hear from you soon.... Best wishes from Hamburg
Vega with this symptoms has probably GPU problem. Only the GPU chips cost more than 50% of working card price. In this case repair is not worth it. If you have another Vega 56 or 64 with PCB damage for example,we can swap the GPU.
"This was a tricky repair, but it doesn't matter." This is why you deserve and earned my respect.
I'm here because of Der8auer. Subbed. You are really skilled. Clean repairs. Good job.
A master !! That's what you are about ! Professional, talented and patient :) Keep on the great work 🙏
this is just ... amazing ... i don't understand electronics , but i love watching impressive battles to bring life to electronic devices as you do ... thank you
Great video and even better explanation. You and the Discord community make my electronics heart blossom again. Thank you.
How can i find him on discord?

Kris, thank you for all the work and info, I have one card with the same symptoms and this video was very helpful
thats a real deep chip level repair, realy good job.
You're the rock man! Thank you for sharing your experience. Do not have enough knowledge to fix fresh AMD cards. Appreciate it.
Man, that's some electronic detective work right there! Very interestng to look at and follow, please keep posting such investigatory videos in the future
Best comprehensive guide in youtube!
Those shifty AND gates 😅, well done 👍
You are just amazing, well done Wirth this one!!
Better Diagnostic than Dr. House!
You could also be a top notch surgeon! ;-)
Wieder mal super Video, du hast es echt drauf. Für mich der beste !!
Fantastic repair, well done.
I enjoyed your video very informative,detailed and professional
The man is a master in his field.
Great job and conscientious in details
thank you very much for sharing this video
Great video, keep up the good work!
Excellent Work!
Great video!!! Please make more like this!!
So much knowledge.
Great Fix. Believe it or not I had the same fault years back on a r9 280. Even the chip was U100 on the board view! SN74LVC Buffer gate. One to keep an eye out for on AMD cards.
love that, a must schematic, and board view, or else no way :(
Impressive! Good job!
without board diagram I think no one can fix this card. People will think this card is fixable but no one have time to check every component.

My impressions too. But the amount of equipment he has is quite insane.

Oh 😇 you are so well educated...just wondering what a shaolinDDR9 master you had😁, any info or link on that magical box showing amp pleaseee.
Great video as usual thanks
Thank You!
Good job, bro!
You are Just Amazing because the way of everything explanation very smoothly.
Just keep it up.👍👍👍
Very great job
nice video.. "ac" is the normal culprit if card didnt initialized (missing PWM PWrok)...
If it was sent to northridgefix: No short- no power=no fix! The more time it takes the less money you make, right? :)
great job!)))
Incredible - how on earth do you get all the schematics?

Top , the best
Good job matte
You are a good!
Hopefully you got rid of the solder bridge on the 1.8V rail chip you replaced!
VERY NICE
Nice...
What type of software u use for the schematics?
it is very though to find boardview or schematic. where did u get yours?
Great Tutorial.. Can you please tell me where I can find the schematics for a ASRock Phantom Gaming 6700XT 12GB D
One of the 2 small smd's near the pcie ribbon connector back side is missing , trying to find that value any help would be awesome

Hello, thanks for the information. You can give me the boardview and the schematics. Thanks for your help.
What would this repair cost a consumer? Nice one.
awesome
Nice fix Kris which test machine do you use on your raid. Can you test an gpu with an laptop.
I have 5 test setups. You can use every MB, UEFI bios and integrated graphics are important. You can also use laptop external graphics adapter, i have never tried it.

Hello,
If you wish you can send your device
I have RX6700XT refab, it works 1 mounth and now no fan rotate and no detect. I think problem with power
Where i can get boarview schematic for graphic cards? I need vga schematics
Hello, where can I find the boardview Rx6700xt. Thanks
Hi. What is the name of the U100 part? How can I find it on Aliexpress?
Want to know too. Where download list of pcb components?
where can i legally obtain those schematics ? i mean buy it
Mantapp...
Is this controller sharing a cost-cutting measure? Seems like a poor way to go about this.
Got the answer to this is if no display detected with fans and LED working.

Thanks for the reply i thing i need to sell it as defekt. Because i have no 56 or 64 at the moment.
Can you send the link of the software for the board view and schematics
This is completely normal boardview software. The files used in this video are confidential
@@KrisFixGermany can i buy them from you because i live from repairing gpus and i need those files relay bad
You can contact me via email or telegram
@@KrisFixGermany thank you very much
may i know the IC no of u100
no surprise after all it is just a piece of amd junk
Hi Krisfix , can u share the firmware or were to find it for the PWN controllers ? Kind regards
