You open up the top back door where the marquee is and take two wood screws out one on each side, they are square head screws, also known as Robertson screw heads.
Then you can lift the marquee assembly out. Then you remove 6 Philips head screws out of the next lower section. Then there are another set of Philips head screws for the next panel around the monitor. So it is not a hidden latch it is a total dismantling process.
