It's 1 day old RTX 2060 (just built a new PC). I tried to connect my PC to LG TV using HDMI connection after plugged in the TV cable to electrical connection after power surge. Then, spark came from the connection. After that, my GPU was not detected in from lshw command (Ubuntu). And nvidia-smi command failed.
The day before that event, the PC-TV connection and the GPU was fine. The GPU was detected by lshw, nvidia-smi, Cuda, Tensorflow, etc.
I already plugged out GPU from the motherboard, wait for one day, and reattach the GPU to the motherboard, but still not detected.

It sounds like there was either a short circuit or ground fault. Try plugging the graphics card into another computer and see if it works. If it doesnt, it is most likely dead. If that is the case, your best bet is to try to replace it under warranty.
