My box works perfectly fine on my old tv then as soon as I put the HDMI into my new tv I get no satellite signal with my f5s box, I've changed the new tv for another one and it's just doing the same thing, then as soon as I put the HDMI back into my old tv everything's working fine, everything else on the new tv is working fine just that I get no satellite signal as soon as I plug the HDMI into the new tv..
