Switch black out mid-game

[man89_au]

I was playing game with the switch on the original dock. It blacked out mid-game. The switch was at 100% when this happened.
Afterwhich, I cannot turn on the switch to cfw or ofw. I tried the recovery mode but it does not work.
No charging icon appeared when charging the switch with the wall adapter. Also tried to connect the switch to pc but it cannot detect the switch. Not sure what's going on here, can anyone help?
Thank you.

Firmware: 9.1.0
SX version: 2.9.3 beta

Did you tried to boot without SD card?

I tried that as well but could not boot it up.
I left the switch charging overnight then tried hard reset. Still black screen

Do you remember if you turned autoRCM on? If so you would need to push a payload either using the Pro dongle, tegraRCMgui from your computer or and Android phone. If that is turned on and no payload is sent, it will just sit at a black screen and look like it's doing nothing.
