Ws-65807 65" mitsubishi rear projection tv
For this unit and the addition of the secuity features of Blu-Ray, the 1080i you set can handle is through the component input from a DVD player or an XBOX. In the configuration menu of the PS3, change the resolution to 1080i and see if your set will reset to it. The 1080i on the Blu-Ray is only possible on the HDMI cable as far as I could find, again due to the security restriction. The Mitsu is not going to run it in 720p due to the PS3 is running component and cannot control sync to this set.
