I got a Mitsubishi WT-46809 with 1080i... The television works fine on
480p without a problem. I had direct tv installed.. with the HD reciever. I can't get the television to do 1080i. When I tell the direct tv to use 1080i the TV shuts off. I have it all hooked up properly. About last year I replaced the Convergous IC's. I'm clueless. It did the same thing with my friends xbox 360... Any help I'd apprciate it!!-Ron
