be especially careful with these bottom ribbon cables, they are the most fragile thing, one misguided or not conscious movement and the monitor is irreversibly ruined, handle the card attached to the ribbon as if touching the most delicate flower petals, and place some masking tape to temporarily hold it in place while you remove the rest of things to follow
In some monitors there is no need to remove much more and the panel will just come out when placed faced down starting from the bottom, there may be a little glue holding the ribbon and card in place, but that's it. But be especially careful with the panel edges, as there may be some sticky tape holding it in place, if it does not come out effortlessly find the tape and carefully remove it, always watch the edges, if they are chipped the panel is gone.
