A7RV bricked?

I was using my A7RV today and noticed significantly delayed power on times in the morning. By the evening, the camera wouldn't even turn on and was just flashing a red LED. The flashes weren't in groups or quick, just a steady on-off pattern. I tried different batteries, lenses, SD card configurations, hard resetted using the Sony guide, and tried install new firmware without success. Has this happened to anyone before?

Fortunately, it's in warranty and off to Precision Camera repair already. I would appreciate anyone's experiences with turn-around times. I have a shoot on Wednesday and my A7RV is my only full frame camera :(
