How to remove living room tv in 4250?

My 4250 TV bracket in the living room will not release the tv when the release buttons are pressed on the mounting bracket.

I can only guess that there are some screws holding it into the mount as well.

I see some screws but they are extremely hard to reach from under the tv.

Is there a speciality tool?

I was thinking a 6.5 inch Phillips screw driver might be the ticket.
