Hi All, on the Sony A7r, there was someone that had Hot pixels and wrote how to remove them or should I say in the process he went threw the camera mapped them out, I think it was DPreview or FM.
Found it thank's to snapsy on FM: Those likely aren't stuck pixels - they're just hot pixels from the long exposure. You can tell for sure by forcing a stuck pixel remapping cycle, which previous A7-series models do automatically I think every 30 days. To force the cycle, set the camera's clock a few months forward then power the camera off. When you do you should hear some loudish shutter noises - that's the camera performing a remapping cycle.
Worth a try?
