Im fixing gpus. If you have no idea better not try do it. Replacing the fuse wont fix problem. If fuse opened it means there is short circuit in mosfets. It is better give to master.
I'm not an expert in the field but I sure know how to use meter very well, the funny part is no single fuse was blown, anyways id just let the GPU rest in perfect peace lol to send it to a qualified person out of my country will cost me much money
If you know how to use meter then plug gpu thru riser and measure voltages for gpu and memory.(Dont keep gpu under voltage to long,if it gets hot it go to protection) if one of them shoving 0v means need to check controller which you need oscilloscope for measure.
