Hi
I have a MacBook Pro 15" mid 2015 version (Mojave) and I still love it, but recently I came across this weird problem with it. One day My MacBook display was off but the system was running I can c the blacklight on the keyboard so I forced shutdown and switched it on, after the apple logo boot my screen goes blank (no login screen) but keyboard blacklight is on.

So I went into Safe mode it was working fine I can see the login screen so I restarted it normally thinking it will be fine but the same issue came up again so I connected to my external monitor and it was working fine I can see the login screen now after the boot. I went into settings I switched off "automatic graphic switching" and restarted without the external monitor and it worked fine.

Is my Mac dead with integrated graphic chip or a problem with my logic board ?? Any help
