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.
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!
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.
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 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
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 @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
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'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.
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.
