Chosen Solution
So my Macbook Pro touchbar was working fine until two days ago and suddenly the screen turned dark blue. I tried all of the troubleshooting options (smc reset, nvram, safe mode) and still nothing showed up. The next morning I connected it to my external monitor and it was displaying everything on the external monitor but still nothing on the mac itself. Luckily I backed up everything while the external monitor was working. Then I rebooted the laptop and now the screen is still dark blue and the external monitor has a blank grey screen. I took out the back cover and unplugged the battery, the display cable and put everything back together again but still no luck. Can someone help me please.
Ouch! At first I had through you had an internal display issue. Now its sounds like you have something deeper going on here. Did you have a liquid spill at some point? Bang the system? At this point you really have no choice other than visiting an Apple Store or independent who has the needed skills to test and fix your system. Where do you live? Country and nearest city? Maybe we can aim you to someone.
