From the photos I am attaching you will see the hinges broken down and made up of multiple items of the Technics base SH 10 B3.
The bottom screw you see should serve to adjust the spring preload, you should adjust that screw by screwing it or unscrewing it to make the cover dust rise.
Also in the hinges of the plinth of the JVC QL7 there is a similar screw; if you tighten it too much, the lid does not remain raised and slides to the ground if it remains completely "unscrewed" the lid remains raised without any problem.
You just have to try to adjust that screw.
