Does anybody have a link to an online manual for the Tristar MX HD PVR Gameplay Recorder Player?

mine started acting up, if i turn it on, 15 minutes later it completely stops responding even if i walk to and press buttons by hand, it wont even turn off. I dont know whats going on, and i didnt pay $250.00 for something that transfers my picture to a TV. I paid $250.00 for a device that records my gameplay in HD, and it wont do what i bought it for, and what it is advertised to do.
