I'm trying to connect my tab to the TV, a Philips 9704 led (46"), but nothing happens when I connect. Via the HDMI it only says on the TV screen "No videosignal", and via the USB it says "Empty". I've tried two different HDMI cables and inputs/ sources, but still nothing. When I try my laptop via HDMI it works as supposed, also using a USB stick works perfectly. So apparently nothing wrong with my TV. Thought it was just simple Plug-&-Play with this? Is there something I need to do on my Tab first? An App or something? My Tab was automatically updated last week,. I use the HDTV adapter for Samsung tabs so I think I've done everything correct so far, or?? Highly appreciate any help!
