I just repaired a gtx 1080 i got from a friend so thanks for the learnings i got from you. also jus curious what was the job of the inductor in this circuit
I originally misread your question and had to rewrite the following reply.
In this case the inductor is just used for input filtering, it prevents AC current from passing to the Buck Converter.
More motherboard videos, more everything you're doing! Great content!
nice video as always! Honestly mobo repair, gpu repair, whatever repair, I'm all for it
What about mental repair? 😲
You can alter between mobo and gpu repairs, they are all good ! Great repair as always.
It's nice seeing a repair that isn't common. Definitely would like to see more of these.
Also the orientation was a good idea cause you can see everything just fine
Also about motherboard repair i think it's kinda rare to find some youtuber repairing motherboard, so i could say it's your opportunity and it's up to you, i enjoy watching your troubleshooting and explanation tho. Aside from that i think most people would enjoy watching some experiments like unlocking the intel 100 chipset bios to support 9th gen CPU, or maybe i've ever heard someone actually sticking ECC memory on the 1150 motherboard and it's working normally.
hey buddy i think your format and decision to place the boards in the orientation its in is fine. motherboard repair is tricky as is, so no need to worry much about the little stuff. you do a great job filming, narrating and walking us through the issues and obviously repairing the problems. so just keep bringing us more of what your doing. its great work, and your a natural. its quite hard for many people to keep on topic and concise when speaking into a camera. keep up the good work
any repair is great to watch keep them coming tech cemetery
Great work, good description of the steps you're taking very easy to follow! Thanks for the video, do make more! I've stacks of 'dead' motherboards and GPUs that I want to try and repair!
Although it is not always obvious what you are stabbing with your meter, your enthusiasm is contagious.
Another great video. I'm learning a lot of knowledge so please keep them coming.
just finished watching this video, loved the diagnosis. the orientation is good! hd footage of clear diagnosis is already so good, even if you did a vertical orientation.
Thomahawk Max, I see you're are a man of culture as well. I'm much more interested in gpu repair, but because of your high quality of content and because gpus are just mobos with a fancy cpu I'd watch both types of videos
We want more desktop motherboard repair !!! Thank you for sharing !!!
actually this got a like from me , good job man and keep uploading mobos and gpus repair vids
I would like to see you repair motherboards and anything else! your are truly a gifted young man!
More motherboard repairs? 🙋 yes please. Dude's a genius. I believe that before any repairs can start, physical inspection is important.
All kind of videos that repair electronics thinks would be Nice man. I like tour teaching style, easy a precise
Hi, I like the diversity of a channel, I think is a good idea 💡 to repair something else.
By the way my favorite channel. Keep the good work , nice explanation ✌️
Great content. Definitely like to see more motherboard repair videos.
Once again awesome video. I thought mostly bios chips are 3.3 volts. Learned something new. I am all in for any component level repair. Thanks
that's what i also thought
Im new to the channel and your videos are good. One thing i would suggest is giving the cost of everything you repair. As a viewer i thinks is something that somehow catches our attention for good. Keep it up mate!
Amazing , would be great seen you repairing more motherboards
Good stuff man, keep it up!
Fine video. Great information. Keep them coming.
Brilliant video. Yes pls make more motherboard repair videos. Thank you
This planet miss people like you!
More motherboard videos please the motherboard in standing position would be nice to see like your explanation very correct and right to the point got many tips about voltages and how to diagnose
Motherboard and GPU repairs are both entertaining and educational, so both are fine with me.
People don't care about the orientation that's way too specific we just wanna learn and maybe tell how you got where you are good vids keep it up. But the widescreen intuition is a great one.
Nice video I will love to see more motherboard videos
Nice video
All repair videos mobo or graphic cards are great
Thank you so much
nice video as always, I enjoy gpu and motherboard repair also
Yes please more motherboard repairs...great suggestion!!!!
Told you guys this man is allways in God mode 😂 top man
its all perfect, nice find n repair
nice video, yes motherboard repairs are interesting too
I would like to see more pc mobo repaire videos, there are not a lot of them on RUclips for some reason. As always great job on diagnosing and repairing, I have a Gigbyte B550 that I want to try and fix.
Nice info, well done, thanks :)
Yes mobo vids too, i like both ,and watching primarily your vids ve repaire 2 gpus and I have at. Least 2 dead boards and stuff laying around,and thaaaanks for making these videos, I love learning, and good job, oh. And the orientation is fine.
Great job man
good job! yes balance between gpu and mobo
Nice Video . Good job
yes more motherboard repair videos please! though i prefer motherboard standing up ( io on the left side)
definatly do mobo's too it helps alot of people out keep it up
This video orientation is good!
There's very few desktop motherboard repair videos in English so that will naturally attract more people to the channel, maybe 1 desktop motherboard repair for every 2 gpus repaired ?
well done man
Mobo repair is a nice content too, all knowledge is good!
Usually the pin number 8 on bios chip is vcc. Also you can take it out and program it with an eeprom programmer. I've 3 of them. But a chip CH341A will do fine for BIOS chips. And I suggest you to put an Inductor back in place because it will prevent of rush current going through.
Already put an inductor back
Great job
please do more..for me is the lighting but other than that its good.
Hi, def need more mb repair videos
Great video! I would have to agree that any repair video would be extremely helpful. I did just have my water block spill into my rear template. Any possibility you could try your hand at water damage on a motherboard?
Nice job, very helpful. I'm repairing a MSI Z390 MEG ACE, which is a beast and deserves to be brought back to life. I've got a question that you may be able to answer, and save this world the travesty of losing a high-end board...or at least offer a best-guess. I can get the board to power on by jumpering the 24-pin connector from the backside of the motherboard, meaning bridge pins 4 and 5 (same as paperclip method to test a psu...but while connected to the mobo). I have to do that because the power switch header is not working correctly. The board powers up correctly doing this header bypass trick and everything seems to work. I can even turn off the board by using the power header once I have 12V rails fired up. I'm fairly certain this is a 5V standby power issue as that is what drives the soft-start circuit...especially since the standby power LED won't light up either. My best guess is it's a transistor issue on the 5V rail. Maybe I'm getting current in one direction but not the other. Honestly, a lot of great boards fail this way. Some cheap 5V component goes out and a very expensive motherboard is tossed in the garbage. Any ideas?
For orientation, have the i/o ports on the left, 24 pin/ram on right, so its oriented like most people look at a mobo when building a pc on its side. would make it a bit easier to see where you are on a mobo, and help beginners learn (if thats your goal)
We want more :)
Good video
Please make more MB videos
Nice repair, I would really want to see an amd rx 5700xt or a Radeon VII repair video.
Ey sup man...
First of all, love your videos, trying to study and learning about GPU fixing I finally landed here... No regrets, good channel.
Second, have to ask about a GPu that I have now. rX5500 XT 8 GB, if I run furmak for 1 hour no problem at all, temps are good (60 C) but as soon as I start a game, it crashes, maybe crash is not the word, it freezes, sounds freezes and I have to restart manually. Thought it would be a driver's issue, but I've already tried everthing on internet... Hope you can give me a thought about this.... Thx a lot in advance
Please more Motherboard Repair vids
Yes more motherboard video please
Please do both mobi and gpu. Could you also please show a process for installing some of the components on the PCBs
Gpu repair or mobo repair, I'll watch it. Not sure how the learning curve on diagnosing mobo are differ than gpu (I assume its much easier) but if you have enough time and resource then I'll be very happy if you can do both.
The format is great. How did you know that you could put in a 0 ohm resistor instead of the inductor? If an inductor was installed in that spot, wouldn't the voltage be different on each pin? I am just asking as I want to learn and I don't know but was thinking that would be true. Thanks for the videos.
it is a wise idea to do desktop motherboard repair as well.
Nice videos. I have an gigabyte 1080ti gaming oc that just went dead. Looking to your videos and doing some checks I found that I have a short on the 8 pin connector. Do you have any diagram for the Gigabyte PCB? And do you think that is completly dead or maybe could be fixed? Thanks
Very helpful info, keep doing what you're doing. I've got exactly the same brown spot on my b450 mobo. What's the reason for this kind of damage? TIA
Hello, I have a X570 board that has the exact same problem as this one. But the 1.8v voltage is normal on the bios chip. Can't find any shorts missing voltage rails or burned or damaged components. Is it worth replacing the bios chip with a new one or does it have a more complex issue?
More motherboard repair videos please.
smash the like more mobo repairs love to see a socket replacenent
Do an overhead camera for mobo repairs
Wow nc video.
This video kind of helped me tbj, have the same motherboard,voltages are all ok, but the motherboard won't jump start, maybe i killed it with a bios upgrade lol
when you said you used wrong type of ram and mobo never booted, did it mean the PSU didn't even fan spin? or mobo turned on but blank screen?
I have a Msi H67MA-E35 (B3) that just has no life in it at all is it normally the capacitors that go I know there’s nothing wrong me power supply as I’ve already ruled that out what would be the best place to start on the mother board I have a multi meter
Why do you use the probes to start the motherboards in your videos? Why not a starter switch? Just curious, great vids!
I don't own any spare starter switches.
Motherboard front panel power switch only needs to be shorted momentary
I have question can "chipsets" make a short circuit in motherboard, because I found many capasitors are shorted, and two mosfet (pin1,2,3 source) that connected to pm_1v05 are grounded.
( these mosfet should not be grounded at all).
Chipset amd 47b2 1851 218-0891011
Mobo is gigabyte b450 aorus elite v.
i hop that you get my point, and sory about my bad English.
hey dude , i have a motherboard with short in to many caps and resistor near cpu and near south north bridge but motherboard run windows system without problem but every time i restart pc it restore to default driver gpu etc , what u think ?
just repair everything what you can repair, it can be very useful for everybody
the bios chip with the 1.8 volt is the soc?
How do you tried to flash the Bios? Have a Problem with a MSI Motherboard where the Bios might be bricked. Turns on normally but no Picture and all Debug LEDs go off normal. I saw that MSI have a special connector to flash the chip but cant find anything in Google.
I did actually, I used the following guide/video to flash it using MSI's bios flash button.

I got my hands on a dead zotac 1080ti extreme amp a week ago. I thought there was a short in the vrms but that was just my meter measuring the die. So I removed all mosfets then put them back and one died afterwards, so I removed 4 which were short. Yes I do feel dumb xd. Right now 1.8 is present, die heats up a bit and vrms warm without heat sinks but no display or detection. I'll try to see if I can have it serviced even if that means paying zotac. Any thoughts?
Heh, no need to feel stupid, I've probably killed more cards than half of my viewers put together. If in future you think you have a short on the VRM, I recommend you take off the inductors instead of the MOSFETs as reinstalling the MOSFETs can sometimes be difficult and if it's even slightly off center it can short and kill the GPU. As for your actual card, do you have all voltages and what is the resistance across the 1.8V, 1V and memory phase?. If you have a short in any of those rails, it's often a good indicator that you have a dead GPU.
@@TechCemetery You have discord?
@@phyro4143 I don't, you can usually find me on r/hardwareswap
@@TechCemetery I posted the pictures on discord.gg/nPsxmU9J
Voltages I get 1.389v, 1.826v, 3.321, 12.04, 1.030v, 0.812v
@@TechCemetery I just measured from the vcore inductors and I got 0.814v, so the 1.826 wasn't what I thought it was. Zotac says no warranty for me because it was resold.
I had a strange issue with a Z490 Tomahawk where plugging in a USB cable into a PCIe USB card caused my PC to stop turning on. Tried powering it with Power SW but nothing happened (no PSU fan spin). Reckon it could be a similar issue to this?
You mostly likely suffered short on the 5V rail somewhere on the motherboard due to the PCEe card. PCI ports use 3.3V, 5V, and also 12V. A USB card in a PCI port will tap the 5V rail for power. It likely pulled too much current and a component burned out. If your lucky, you can find a smoked component and replace it. Otherwise, lots of testing to find out what actually went bad. Sucks...
orientation, and everythign its ok this way, more videos about mothers and psu whould be awesome, gpus are the king but sometimes you dont have enough make a daily video .. thx so much for ur knowloge will add you on twich to give u some gold, later my man
More board repair plz
do more motherboards, in fact both are good, do them both, do one motherboard and one graphics :)
Nice, btw i got rx 550 for only $5 from my friend, it's powering on and detected normally on GPU Z when im using IGP, but no display or anything on the GPU video out. Is this problem actually because of the display IC near the bios chip or what?
I still have my old R9 270 tho but it's power hungry and i want to retire this card with the more efficient one, probably for short term until the GPU shortage finished
Can it load drivers, and if not, is it detected with error 43?.
The driver installed correctly, and yes after installed error 43 pop up. I've tried to reflash the bios with the original bios and the error is gone but unfortunately still no display.
@@accurian148 Can you run any games on it via "Graphics settings" under windows when used as a secondary GPU?. If you don't know, graphics settings allows you to pick which GPU is used for certain programs. You can manually select the RX 550 on a per game basis provided you link it correctly to the game's executable file.
@@TechCemetery I've try that after watching linus video about nvidia p106 video. I would say yes but it's a little bit complicated, i could only choose either intel hd or the rx 550 based on the driver i installed. If i only installed the rx 550 driver the performance crappy af and the gpu never run on full power, but when i installed intel hd driver or both driver installed the rx 550 suddenly gone on setting, can't be used for anything, just sitting doing nothing.
@@accurian148 Wow, I'm kind of stumped actually. What RX 550 is it?. Right off the bat, I'm curious if you have power on your display ports. DVI uses 5V, HDMI uses 5V, and DisplayPort uses 3.3V. You can find the pinouts for them on google. I mention this because the drivers for GPU VRMs and memory VRMs often heavily rely on 5V in one way or another.
I've got a multimeter, a soldering iron, and three dead motherboards. Bring it!
I likely have the same fault. Because suddenly, I walked into my second room, I unexpectedly found it off, not even any LEDs, TMK! And when I try to power it off from outside the case, I get nothing! It's like there's nothing connected to the inputs! There were no bangs or pops that I noticed. (mine's not the Max or the "II")
What's the card in the memory slot at 8:50? Doesn't look like RAM because of the pins sticking out
It's a DDR4 Sodimm adapter - it lets you use Laptop DDR4 in a desktop RAM slot.
I have the same problem the same mobo wit ryzen 7 2200. so when the cpu was installed it would not power on and then, when it was removed it power on. was able to do a bios flash but it still the same problem.. tried swapping memory and it would not. can you help me?
🤧 U'll get it done!!🤖 that tickles!!!🍟👀🛠️ U are absolutely correct!! good job!!🖖 U need an oscilloscope? could make everything more complicated!!
do U care 2 explain what U'r fixing a little better? I would have liked 2 have seen U repair the ''micro'' diodes,transistors. or what ever was the fault!!!
small components can be tedious!! I wipe solder on the component..some people use a solder paste...good luck!!
i want more mother board repair
Please Vega 56 not working Fans spin but the pc black screen hd I have never opened once power went off and got back this happened 😞.
Both 😀👍👍
Hello i got similar issue but i could not see where the damage capacitor or components in the motherboard can you give me some advice btw my motherboard model is B450M mortar max
Additional info the mortherboard could flash bios but if put my cpu it is not opening too same as your condition i hope you could give me some advice thank you
Does this motherboard turn on without the CPU? I have an MSI H410 A PRO and I would like to know if it connects or not without a processor. Someone help? thanks!
I need your help, how can I contact you?
are u active on discord?
my b450 mortar max just died last night and im learning how to diagnose it,it'd be really helpful if i can ask u some questions as im working on the board.
