Hi all, New member hoping for some advice/suggestions about a strange problem. In summary I have just got a new samsung tv, and on connecting up everything works apart from the virgin box which says no signal and also intermittently reboots. Confusingly this was/is working fine using identical cables/set-up on an older HD samsung tv. ** My set-up : Sources 1) Virgin Tivo - has always been set to output at 1080 via HDMI 2) Apple TV 3rd gen 3) Sony Blu-ray player - are all wired up via HDMI to a 4x2 HDMI matrix (KanaaN HDMI Matrix 4 Input 2 Outputs Splitter Switch - 3D Enabled - FullHD 1080p + Remote Control + HDMI 1.3b + Cinch Audio Output) outputting to TVs A) Samsung UE40ES6710 ("old tv" which works fine) B) Samsung UE49KU6400 (brand new tv, replacing an even older HD samsung tv in this set-up) ** Problem Both TVs can receive (2) apple tv and (3) Sony Blu ray. (A) also gets (1) virgin tivo signal (B) gets no signal from (1)....even whilst (A) is showing the picture fine? Also when I first plugged in the new TV, when I connected the HDMI cable the virgin box seemed to get stuck in a reboot loop - all lights flashing on front etc. I was doing this quite late at night and was getting tired, but at some point I *think* the new TV (B) may have shown a signal from virgin saying it was restarting, but am not certain. I've tried powering everything off and restarting to no avail, also swapped HDMI inputs and no change, (B) only ever says no signal when virgin is source. Have not seen any HDCP error messages on TV. So as virgin box works it doesn't seem like a virgin prob, but as TV can receive apple tv and blu ray OK it doesn't seem to be an issue with HDMI matrix or new TV ? (After googling for solutions I did find that I should never re-wire hdmi leads whilst power is on, so hope I haven't fried anything. I assume not as Blu-ray and apple tv still display fine.) I will try hooking Virgin direct to TV as haven't done that yet, but would welcome any other suggestions. Scratching my head as to what else to try next...any suggestions welcome !
