Toshiba 46HM95 will not display 720P channels from DTV antenna anymore. I get audio but no video the signal bar show full 4 bars. used to work fine. I hook up the antenna to another TV and it works fine. all formats. Here is the weird part... My XBOX 360 works fine throught component cables and the TV displays 720P fine with that. However the signal from the anttena is only working for 480p channels and any channel that has a 720p output does not work. Audio no video. So makes me think it's the TV tuner inside the TV. Help me please...reference to parts to fix or a receiver that has an RGB component out so I can keep the HD signal from the antenna to the TV.
