Hello i got a card with 12V short, found an IC blown Q510, remove it short persist, found that the short is on 12V GPU, remove all the Mosfets and the short still there, i inject 1.5V to the line and i got 1A of consumption, nothing getting warm, this could be the GPU itself?

if u remove all mosfets u canot have 12V bypass to mem and core. u need at last 10A with 1V to show something on thermocam. q510 switching 12V . looks badly shorted. heat can fuse layers under itLast edited by ktmmotocross; 12-23-2024, 02:58 PM. -
I see, thanks for that info, also I didn't check that the resistance on Vcore is low, I was thinking it has a high Z, one of the MOSFET is shorted so now I'm checking that to replace them and also fix the q510 got a destroyed viaComment

Hey!
I have a problem with Gigabyte Aorus 1080. The card seems fine (expected resistance on vcore, pex, 5v, 1.8v, 12v and reset) except for a dead short on vmem (FBVDD). It's interesting failure mode, cause usually (in my experience) when memory fails it still retains a few ohms - this one is literally a dead short.
I removed the inductors and tried inject voltage (0.8 V at 6 A) which only seemed to warm up the cables to the card while the card itself didn't show any hotspots.
Is there any way to narrow down the search for a short? I would prefer not to remove... -
Hi Folks
I'm looking for a extreme high current short killer solution for a reasonable cost.
I have an LGA1700 motherboard (ASUS PRIME Z790-P WiFi) where I exchanged the LGA socket already 3 times, and every time after the socket exchange I get a short of power supply lines VCORE (V variable) and VCCIN_AUX (1.8V).
After taking off the socket, the shorts dissappear again.
The soldermask on the socket is already partially demaged from the heat, so I have reconstructed the soldermask by manually painting the missing soldermask parts with a very small top of a...10-15-2024, 10:13 AM -
NVIDIA GeForce GTX 1660 Schematic & Board View
The GeForce GTX 1660 is a performance-segment graphics card by NVIDIA, launched on March 14th, 2019. Built on the 12 nm process, and based on the TU116 graphics processor, in its TU116-300-A1 variant, the card supports DirectX 12. This ensures that all modern games will run on GeForce GTX 1660. The TU116 graphics processor is an average sized chip with a die area of 284 mm² and 6,600 million transistors. Unlike the fully unlocked GeForce GTX 1660 Ti, which uses the same GPU but has all 1536 shaders enabled, NVIDIA has disabled some... -
Hi there,
I discovered this forum through a youtuber who teaches electronic repair. I've been trying to troubleshoot my dad's old PC which is a Gigabyte GA-H61M-USB3-B3 and will not power on. I discovered a dead short on the 3.3v rail at the ATX connector so I used a bench power supply to feed 3.3v into the ATX connector and sunk about 400mA into the board (I hope that's not too much!). I used a FLIR camera to identify the problem area:
The chip seems to be the following, an ITE IT8892E 1108-CXS which seems to be a PCI bridge?
