some photos of the board would be nice... its possible u burned something when u shorted the cpu fan header. maybe the pwm fan controller on the board? also what psu is this? if its a junk no name psu, the psu may also be toast from the short on the 12v rail.
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?...
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...
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...
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?
So i got this RTX2070 Super from Gigabyte for cheap and the reason i actually got it in first place is, because it initially had a full short on PCIE_12v, so my plan was to basically feed some juice in it on my test bench and see what gets hot using my thermal camera. This would have potentially been a quick repair, however things didn't actually work out quite as planned.
Whenever i hooked up one of my lab power supplies to my testboard to feed the 12v rail, well, even tho i had it current limited at 12v, the charged capacitors actually blew the 10A Fuse...
