We are trying to stream movies from IPAD to Hitachi TV L46S603. We're purchased and installed a new modem/wifi router, and updated Hitachi software, but cannot get the picture from the ipad into the tv
if you don't get a picture, then something in the ipad needs to be turned on or the tv is on the wrong input. It has nothing to do with the wifi/modem/router. No picture means something not working.
I assume you have some kind of adapter to connect the iPad to the TV via HDMI. If you can't get any output when playing files that are on the iPad rather than streaming through it then the problem is the adapter not the wireless connection.
