Errata 0:40:39 - this pin is connected to ground on the ATX PSU but it is not connected to ground on the GPU - it is a sense pin to detect if an 8 way plug is inserted
Errata 0:43:25 - 12V not 5V
Errata 0:48:44 - Yes I know, I am trying to probe the coil in the wrong place!
Errata 0:52:25 - We also need to test shorts to the coils from the 12V on the PCIe connector
Errata 0:56:20 - and this is why you need to check ALL the phases of the VRM for shorts to ground. It could be possible to have a short on just this phase.
Errata 0:59:45 - The memory controller (which reads short) is part of the GPU
Errata 1:04:06 - it is also common to find a coil in this area which is actually a filter for the 12V PCIe supply, and not a buck regulator coil. In that case it will connect to the 12V PCIe and likely (to give you a clue) to have a 16V capacitor connected to it as well
Errata 1:09:17 - PEX is the 0.9V-1.0V supply rail, we'll talk about it in detail a little later
Errata 1:23:58 - On modern GPUs the BIOS is often powered from 1.8V, but on lot's of GPU it is 3.3V and on vintage ones it could be 5V
Errata 1:35:18 - This coil could also possibly be a filter on the PCIe 12V supply coming in
Errata 1:37:13 - I should say 'sometimes on either end'. It depends on the type of regulator, the input or output voltage could be on the tab
Errata 1:38:15 - IC U9 could be the 1.8V supply
Errata 1:23:58 - On modern GPUs the BIOS is often powered from 1.8V, but on lot's of GPU it is 3.3V and on vintage ones it could be 5V
Errata 1:35:18 - This coil could also possibly be a filter on the PCIe 12V supply coming in
Errata 1:37:13 - I should say 'sometimes on either end'. It depends on the type of regulator, the input or output voltage could be on the tab
Errata 1:38:15 - IC U9 could be the 1.8V supply
Errata 1:45:36 - Or the memory VRM is faulty
Errata 1:53:34 - Yeah I think I measured both ends of the same coil, instead of checking both coils
Errata 1:55:20 - I meant to say I forced to to produce an Enable signal
Errata 2:01:08 - This middle pin is probably the reference pin actually, the input voltage will probably be the left hand pin
Errata 2:01:22 - A vintage board like this may not need PEX as the main Vcore voltage is possibly high enough to handle the interface with the PCIe directly?

Just for those reading this top comment, in CHAPTER8, if you are going to check BIOS, also check if GND is shorted to GND and if VCC is present or not. Flashing AMD bios is easy with software (while using another graphic card or integrated), but for Nvidia you have to remove bios chip, flash with programmer and solder back.

🙂Thank you, This is what I do, teach how to understand the item, be it a GPU, a motherboard, PSU or whatever it happens to be. Teach people to understand how things work and then they have a much better chance to attempt their own repairs in a logical manner when it doesn't work, because they actually know what they are doing and are not poking around aimlessly. After that it just takes practice and anyone can be an expert. This does tend to make my videos quite long, but then I think, if people don't have the patience to learn then they probably don't have the aptitude for this sort of repair anyway.

I've used them to repair tablets and monitors, but the pc components are clearly built different. My suggestion is to not ignore having the right tools for the job!

Anyone who already has a good foundation in electronics will certainly add knowledge about GPUs with their explanations, which are perhaps one of the few really detailed ones here on KZbin and much better than some paid courses. Understanding the sequence and operation of equipment is essential for diagnosing defects.

Strangely enough - I worked professionally as an electronics repair engineer for about 7 years, then went into computer programming where I earned about 50% more money per hour for an easier job (from personal experience) for three years but I just wasn't happy with life so then I went back to working in electronics repair as I found programming too boring and repair more challenging and interesting. I made less money but I was much happier doing repair work. After a couple years of that I went self employed instead which, again from experience, is the ultimate combination of doing something interesting and making more money than a paid job, even in programming.

Noted. The motherboards are more complex and less generic (almost all GPUs are basically 'the same') but I would like to have a go at that at some time in the future

Sir thank you. Following your steps i was able to trace faulty buck converter. How ever, it was only possible because i had boardview and schematic. Otherwise i would not be so lucky without experience.

@Tony Nameless Well done. Boardview/Schematics always help but you can also do this by looking up the part numbers of the VRM controllers and finding the datasheets. Armed with just a datasheet you can diagnose a faulty VRM. There is a very large collection of free schematics on the Discord server. Learn Electronics Repair is now on Discord! Come and join the fun and let's fix stuff together, it's free and a nice place to be. discord.gg/vam6YC8vwU

I am not interested in electronic at all. Just my graphic card 1.8v power regulator chip has gone, as I found reading through forums (as soon as I underclock the card, it works perfectly!). I found your video. Ok. This is not guide.. this is engineering university course! My bow to you sir, to share your skills and knowledge here, in the ocean full of wasteful videos. So elaborate video, huge effort to explain it even to me, who know just how to do the socket circuit in the house, or max two way light switch. You actually learned me how to use multimeter too! Once again, huge thanks!

The last part would be more than interesting for me. The request part, the logic between you´ve mentioned in the last minute of this video. I hope you will do it in one of your next videos.

Thank you very much for this good work, i would like to ask a question, what are the most common types of those 3/6/5 pins logic components that are a must have in the components inventory?

Yes they are essential to keep in stock for GPU repair NC7SZ08P5X very common type www.aliexpress.com/item/1005001836908960.html?spm=a2g0s.9042311.0.0.27424c4dYnOIoI Not expensive either

Thank you for this information , you helped me ( plus reddit) to find the problem with my GPU (1050ti). I just want to add : i found all voltages on the gpu , they were fine but does't get detected , after i flashed the flash it gets detected after a 30 second or so but blank screen with monitor backlight ON . I ran a memory test with mats (Mats and mods from nvidia) and i found out that one of the memory banks had errors , I'm going to replace it soon and update the result . I hope this helps someone fix there gpu also . Have a good day

Nice work - let us know how it goes once you got the replacement parts. This symptom: it gets detected after a 30 second or so but blank screen with monitor backlight ON . is very typical of faulty Vram on Nvidea cards
