i have a gigabyte rtx 3060ti gaming oc pro on servicing,it experienced no display issue because of physical damage after oxidation problem(probably because of humidity).after 2 days of investigation the gpu repairer said that he is not getting any signal from gpu,his best guess is the chipset is done and dusted. i have a doubt that the repairer might have changed my gpu chipset with a bad rtx 3060ti chipset so that he can give me my gpu back with damaged chipset and use my gpu's good chipset with his old rtx 3060ti where that gpu's chipset was damaged,,that way he can get a new rtx 3060 ti for free and i can be deceived by possibly damaged chipset exchange with good chipset.gpu servicing takes time,,at least few days,,within those servicing days we can't know if the repairer changing any components with damaged ones from his shop or not.what should we do in this situation?thanks in advance
