How I Fixed My RTX 3090 Not Detected Issue

Welcome to Graphics Card Repairs! In this video, I take you through the step-by-step process of diagnosing and repairing an Asus Tuf RTX 3090 that wasn't detected. Follow along as I dismantle the GPU, test resistances and voltages, identify a faulty AND gate, and successfully bring this powerful graphics card back to life.

Perfect job as always my friend, thank you

[marwaanmk]

Excellent work buddy .. really proud of you and how you identify the faults .. keep up the good work brother

I didn't understand how you found out at 3:25 that the faulty chip has to be an N gate (MOSFET?). Can you explain?

[RuwanTech]

Great. Trace done with board-view or manual? I keep extra AND gate ics for backups. We don’t have donerboards here in Sr Lanka 🇱🇰

Great video!!! Which flux are you using?

As the VRAM, mosfet and, top of all, GPU will heat as hell as you turn on power supply, is it safe to test voltages without any kind of cooler ? I'm currently working on a RTX2080ti, it is very hot even when idle

Awesome repair as always, thank you for your great helping videos, keep it up brother, and if you spare some time I have a little question, I had an rtx 2060s from gigabyte with micron memory 😢 and c1 faulty with 200k or more errors, so I replaced it with a new one, and now the gpu pass mats test, but the problem is in furmark, after about 5-10mins of stress test, I get a blue page, and pc restarts, and at that time exactly I do another mats test, and I see A1, b1, c1, d1 faulty with a very little number of errors about 80, and if I shut down the pc and let it rest for few minutes and turn it on and test I get no errors and pass the mats test, can you please help me out, and thank you again

Do you spare GTX 780 FE blower fans? I have the card but when I tried to dissamble the fan from the gpu it cracked from beneath (the plastic that connects to layer just above the die and pcb)

What is power supply for testing? I want to buy this

[mainejason]

What is your suspicion as to why the gate would stop functioning? Heat? Another faulty component?

[mamurii]

what's the and gate?
is that N channel mosfet?

[NotgamerGOD]

can you share the tiffin box power supply diagram?
