Missing the plate that goes on the top of the unit. So i used a little screw driver to slide the on/off switch. I had this working, it has a couple of Micheal Jackson videos on it and a bunch of photos of a family on it. I dont know maybe when i hit the reset button but now it just says connect the portable media center to p.c. All the buttons worked as should it took me awhile to figure out to use the button like a joystick. The volume worked fine also because i was listening to the jackson video. This will need a little work from somebody who knows or is learning electronics. It will need a power supply im not sure but maybe a charger a new part for the top unless someone modifies it, this was just playing a video very good and it sounded good just a hour ago. So it is very capable of working very well. Its possible it might be a easy fix for someone. Hopefully it is not a pain in the ass.
