Guys please: Before you attempt to diagnose GPU for faults, please have the following: #1 Multimeter #2 GPU it self Believe it or not, #2 is often not available.
@@mwhunter2346 thanks i think this one is much easier to repair that the other 1660s that i have(it was a Galax with no display but with power) cause the artifacting GPU I've mentioned was also a 1660s(MSI Ventus)
Dude. I went over the mostfet route… found nothing. Visual inspection looked fine. Then you said… just look at the caps near the connector at the back… what do you know. Solder 2 missing ones and fired right up! Thanks!
Thank you very much, you reassured me. I have a computer that fell on the ground while it was working, and when I turned it off after it fell, it did not turn on after that. When I checked it, everything was normal, but the vga circuit I suspected that it had shorts, but after I made sure I found it a small resistance in vga and not outright shorts
I wanted to let you know that I found your video to be extremely helpful in understanding what's going on under the hood. I'm just starting out learning and it's very important to be taught with sound doctrine. Thank you for helping me understand more than I did yesterday and a little less than what I'll learn from you tomorrow. Because the videos will keep getting better. I'm so sorry for asking this question, but I felt compelled to do so. Would you be so kind and tell me where I can find out every single tool and software that I need to buy to get started. Everything from power harnesses, soldering iron station, cleaners, hand tools, scopes etc... I know it's asking alot and I'm sorry, but I want to get started the right way and a tech is only as good as his tools. Also can I buy a great scope package from you? Or could you recommend a great setup like one I'm sure you have at your shop? Anyway, thank you for a great video!
Hi. beginner here. You mention at around 00:40 a video you have on component recognition. Can you link me or give me it's title (I have looked but can't find it) Thanks. I'm finding your vids informative but often a bit advanced. One step at a time right.
Thank you very much, very informative information and video. I’m trying to learn pcb diagnostics myself as I’m an auto technician but I’m very tech savvy. You’re very smart and again thank you this video has valuable information and I will be using it to help me as I’m trying to get into the IT world and learn everything that I can. Videos like this are very very helpful 🙏
This is very usefull, but I am playing more like with AGP cards, so I would appreciate such tutorial on something like GF6800 which are very often dead. 🙂
Thanks a lot for this guide, it's very useful and understandable. In my case visual inspection looks right, but there is a lot of capacitors in short (3 near the PCI slot connector, and 6 at the back of the core), so I suspect it could be a dead core, but since I'm a beginner, what do you guys think?
Thanks, it really helps, i know there are several low coltage rails on gpu, i just dont now which one is which, i just always randomly measures a large capacitor for voltage, i have 5cards here but only got 1card working because lucky enough its just a shorted low side mosfet, the others are a nightmare for me since i dont now where to start at live testing a gpu
@@RobinDobbie it was an earlier guide he did on what diagnostics he runs on gpus. But that one sounds good too lol I think I must have missed it. I'll check it out
Hello i hope you doing well I have a issue with my GPU if i place 8 pins cable there is no display if i remove the 8 pins cable it works i don't how to check if there something with 8pins port !
For every GFX Card there soooo many infos about where is what in the internet. u dont need to know everything. all infos are present. gfx card repair is soooo easy, there is nothing special on it. the most magic happens on the core, so all around is only power, pex and some logic gates, some modfets (thats killed mostly). Easy going, making money ^^
hello friend, I have a gtx 780sc evga 3gb P/N 03G-P4-2784-KR like your video card... I have Coil Whine problems when I enter some heavy application like games or renderings. If I change the R22 inductors (6xunits) do I have a chance of solving the problem? Is there a way to find out which inductor is bad or should I replace them all? do we have another solution? thank you this noise is driving me crazy!!!
شكرا جزيلا طمنتني ، لدي حاسوب سقط على الارض و هو يشتغل و عندما اطفأته بعد ما سقط لم يشغل بعد ذلك ، عندما فحصته كل شيء عادي لكن دارة vga شككت ان بها شورت ، لكن بعد ما تأكدت وجدتها مقاومة صغيرة بالvga و ليست شورت صريح
Hello i got msi gtx 970 in new to this. I messured everything and thers no dmg or short circuit. but thers no video and Gpu core is cold ( so it's not getting power) Fans are spining..
I have a b2 error code Tried almost everything Reset bios button And it did worked like normal and when I turned off the pc it happened again Any ideas how to solve
Hi, may I ask you, where I can talk / write to people like you? I'm struggling with my gtx 980, which force my PC to restart if 1. I connected two monitors and 2. Start an ego shooter.
Where does the „global“ or singel enable signal for the controller come from ? I already replaced a blown powerstage on a 3,3v plane on a saphire 5500 xt. But although i succesfully removed that short i still have no enable signal on any controller. Also i measured 0.4v on the enable pin of the Vcore controller. Wich is according to its datasheet the fault voltage. I need to know where the fault has its roots.
Btw all fuses are good and all power inputs are good in terms of voltage. I honestly dont know what the 3.3v rail is for :D and it might help to know where the enable signals are generated in order to seek for another short. Pretty sure the powerstage blew because of another issue
hi, if pex rail resistance below 3 digit (possible short), will the core still getting warm? because my dead rtx3060ti core still warm and getting hotter with all voltage present. I want to make sure the core really dead before I use the card as my door stopper.
I'm getting current shock on my PC. When I removed GPU from PC; it works normally and doesn't give shock. My question is is this because of fault in GPU or SMPS ? Please help : |
I have a PNY RTX 2080Ti that will boot and the screen will come on and I may be even able to run Heaven for a few minutes but then I get a black screen and the Blower Fan turns on Max. I then have to either do a 5 sec power cycle or turn off the main power to get the computer to reboot. I have noticed that I am missing a lot of ceramic Capacitors on the back of the card. I would begin replacing the capacitors but I don't have another 2080Ti to get them from. What should I do?
I have a 3060 Ti that gives me code 43 so I want to check what is causing it. GPU-Z can read the BIOS, the VRAM frequency, even the driver but not the size of the VRAM. I dont really get artifacting like most common 43 errors, in fact the card works every time I restart PC, it works for like an hour then the screen goes dark and PC restarts. The funny thing is it passes furmark test and gaming, but again it randomly crashes. I suspect maybe is BIOS chip but I have ZERO knowledge of PCB layouts, or how to use multimeter thats why im here lol but any way to identify BIOS chip and how to test it with multimeter? EDIT: I checked ASUS download center for BIOS update on my GPU but it says there are no new updates for it.
Hey there! I have a reference Rex 5700XT, that displays, but crashes the system when under a load. I tried doing the steps you said here in the video, but I haven’t found anything. What should I do?
