 Not sure if this isn't how it happens on actual arcade. Many machines will require power down or a reset cycle (save and reload of nvram) before settings are take and used correctly.

 If you cold reset, or simply exit the service mode after flipping the screen (and it goes black) then it will return. I think this is intended behavior. If anyone can confirm on real hardware, that'd be great. I'll acknowledge this pending further investigation.

 Got information from Tormod regarding this:
Tested this:

Enter SETUP
Enter 1. DIP -SW - SETTING
Change SCREEN FF to ON
Scroll down to
9: EXIT
Hit Button A

Screen immediately flips upside down without any power cycle.

So, the black screen happening doesn't happen in original, this looks to be a valid bug.

 I wonder if this glitch is somewhat related to 05467, although that was fixed quite some time ago.

 It is unnecessary to bump a report. Please refrain from doing so.
