ASUS GU502LW Booting Issues and Wi-Fi/Bluetooth Failures – Need Help

I’m having a persistent issue with my ASUS ROG Zephyrus M15 GU502LW where the screen stays completely black even though the power button light and keyboard backlight turn on. The laptop has been opened multiple times by both myself and local technicians, and we even replaced the motherboard, but the issue still continues. Previously, it would sometimes boot after doing multiple hard resets (holding the power button to force shutoff and restarting), but now even that doesn’t work and the laptop won’t turn on at all beyond the lights. I’ve also had ongoing problems with Bluetooth and Wi-Fi not working or randomly disconnecting whenever it did manage to boot. I’ve tried connecting to an external monitor with no success, and there are no beeps or error indicators. Power and battery seem okay, and the laptop gets slightly warm, suggesting it’s running in the background. I’m really stuck at this point and would appreciate any guidance on what could still be causing this, especially since even a new motherboard didn’t fix it.
