So right now my macbook pro is having somewhat of a similar issue to yours. I know it’s been a while but if you still need help I don’t know how to fix it permanently but I’ve found that turning off the macbook completely then removing the charger and disconnecting the battery then waiting for 10-20 seconds while holding the power button and then reconnecting only the battery and turning it on makes the screen work again. If you managed to find a permanent solution would you mind posting it here?
