What size screw is used on the back? It's appears to be an Allen-sized head but is larger than 1.2 but smaller than 1.6 Allen wrench. The HDMI connector requires re-sodering as it's loose and won't connect with the cord, thus not powering up or being to use it.

Those are very small torx screws. Try a T-5.
