A1932 Black Screen No Startup Sounds But I Think It Turns On Macbook Air 13 Retina Display Late 2018

Chosen Solution

So we got this Air - Late 2018 A1932. Which I think turns on, the fans are sometimes spinning, and/or the logic board gets a bit warm, so I think there’s some kind of activity at least. Here is what we know so far : Black screenExternal screen not working (tried with USB C adapter with HDMI port)No startup soundTried disabling some of the connections like battery, speakers, audio jack board etc - no luckDifferent charger - no luckNo visible fluid damage I don’t have much experience in these “newer” MacBooks, so could anyone suggest what I can test next? I dont have the skills to do “component” testing. But any guidance or suggestions would be awesome!
