2018 MacBook Pro Turning on but no video

I have a 2018 15” MacBook Pro. The display doesn’t work so it’s being used with an external monitor. It suddenly stopped outputting video to the external monitor. But it does turn on (the fans spin and the caps lock key can light on). I’ve tried different monitors and cables. I’ve reset the NVRAM and SMC and tried the standard troubleshooting. There are no signs of water damage. I put it in DFU mode and did a revive and restore using Apple Configurator.

At one point it did start displaying on the monitor for a few minutes and I started booting to internet recovery mode, but then it stopped and hasn’t displayed on the monitor again.

Is there anything else I can try?
