yesterday, my macbook pro fell off from a chair, and it was in my back pack. when I turned in on, it works and the apple logo also turns on but the display shows nothing. I did all the reset of SMC and PRAM, but no luck. I connected to TV, it works fine, does that mean my screen is broken or something?
If it’s lighting up a blank black screen, the LCD cable needs reconnecting. Reconnect it board side and screen side (if it doesn’t work after reconnecting board side), after disconnecting the battery. Very common issue after a drop.
