Screen stopped working, now laptop won't post

[Shrox]

My HP omen 17 was sitting on my table, and the screen just went blank. I tried restarting a few times and connected it to an external display, and it showed up there. But it wouldn't even recognize any internal display - tried updating drivers, rolling back drivers, etc. than it stopped showing anything on the external display. Tried everything, reseated the cable, swapped ram etc. Also this website won't let me input my OS or product type for some reason. Windoes 11, 17-ck1020nr

• Power: Reconnect the battery and power supply and attempt to start the laptop.

External Display Connection:

• Check Connections: Ensure the external display is connected properly and powered on.
• Try using a different cable or a different external display if available.

Reseat Components:

• RAM: Remove and reseat the RAM sticks. Try starting the laptop with just one RAM stick if there are multiple.
