Hi, I have the ONYX STUDIO with the silver ring that serves as the stand and the handle at the same time. After removing the front grill, I find the same five holes as it is shown on your pics but there are no screws. I can just see a bottom made of plastic. Do you have experience with that? Is that just some cover I can get thru using a screwdriver and I find the screws beneath?

I want to look inside as I am facing the problem with not working battery. As soon as I unplug the power source, it stops working.

Thank you for your comments.
