Betson Imperial 27" Monitor Help

[miles2912]

I turned on the arcade last night and there was no picture.  The pc is outputting a signal so I start to look at the monitor.  After removing the back of my cab I see this.


It looks like there was a board attached to this back part...


Looking down I saw the missing board. 


Another shot of the board.


Does this just plug back in and work.  Is there anything special I need to do to re-attach it?  I know this is some nasty voltage back here so I want to proceed slowly and ask someone who is more knowledgeable than myself.  The monitor is over 10 years old, but was working like a champ up until last night when I first noticed this.  Thanks for any help

line it up correctly and put it back on,no nasty voltage on a neck card without power-infact no voltage anywhere on that chassis without power
