MacBook Pro stuck on startup, gray screen on safe mode, recovery mode, internet recovery
Normal startup has Apple logo, stops when progress bar reaches half way.
Tried resetting PRAM and SMC. Pulled and reseated RAM.
Booting in safe mode, recovery mode, internet recovery, off time machine
all end up with gray screen .
Anything else to try before taking to Apple?
Thanks.
MacBook Pro 15", macOS 10.14
