Im having troubles with a few consoles on my Mitsubishi 52" RPTV HDTV. Honestly it took a while till I noticed a problem, first off I have HD cable, 480p DVD, and Xbox 480p. When I boot up the Xbox now, it flickers like scrolling fast, when in the dashboard, or initial load. as soon as a game comes up though its in 480p and everything looks fine. I let that go, because it didn't affect me. Last week I tried my Dreamcast, and plugged it in using composite, and I couldn't get a picture. I sold it to a friend, and it worked fine on his TV, so its not the console. Tonight I tried to play my Turbo grafix 16, and Im plugging it into Antenna A input(coax), and I cannot get a picture. what could be wrong??? Im totally out of ideas here. Will a TV work fine in 480p and 1080i and not work with 480i?? Also I had to not use the netcommand setup stuff, when using my Logitech 880 remote, could this be a problem?? I screwed around with that tonight, but it shouldn't affect the antenna input at all. also when I did the ANT - A scan I didn't pickup any signal when my Turbo Grafix was OFF, but when on, Channel 3 was found, so Im pretty shure its working.
