I picked up a no power Gigabyte 980ti G1 gaming off of eBay to repair. I figured there was a short on it and that it was probably a mosfet blown. Upon quick diagnostics I determined the pcie fuse is blown and there is a short somewhere along the pcie rail.
90% of the capacitors have continuity to ground on both sides of the caps. All of the GPU vcore inductors have continuity of both sides to ground. The pcie rail inductor and shunt has continuity however the 12v rail/shunts does not have any shorts. The data pins on the pcie connector are not shorted so I believe the GPU die is fine. This was all within a 30 min quick diagnostic. Where should I focus my search for the main short? Toward the beginning of the pcie rail by the fuse? I was thinking I could remove the pcie inductor and see what side of the board the short is on. Does this seem like a good plan of attack?
