I can't get my money back but the person who sold it is willing to pay for the repair costs. She provided all her details and willing to work this out. Its an elderly lady who kept the camera in mint condition but I think maybe while in transit from her place to mine, something may have become lose - Parcel handlers aren't always the most careful folks. Its sucks because I love the sensors on these Xtrans-2 cameras and wanted the XT1 to be a backup when my XE2 dies. In any case, the lady already spoke with an authorized Fuji service provider (recommended by Fujifilm locally) and I just have to go deliver it to them. But before I do that, I was curious if anyone else experienced this before on any of their Fuji camaras because apparently the repair can take a month or two based on part availability? One person I know from another photography group said they experienced this with their XT4 and thinks its a mainboard connecter. Another friend of mine who uses Sony had this and claims the motherboard is dying. I'm thinking if there is a connector on the mainboard that measures the temperature? which may have become loose.
Like I stated, the XT1 within a 1-2 minute of being on it gives me the "high temperature" warning then shuts off. This is with minimal usage like browsing the menu or simply taking photos. I'm not doing anything intensive like shooting videos or continuous focus shots. Even in idle the camera gives the high temp warning and its not even getting warm, I'm using it in a mild environment. If only there was a way to turn off the "high temperature" - I think some thermal connector may have become lose and its likely not even overheating but just sending the warning message instead. I wonder if the mainboard has some connected that measures the heat temps (?).
