Hi guys, First ever post and surely there's no place better for a concise answer to this. Recently I got my room plastered with HDMI cables ran inside the walls. Fast forward to now and when I tried to connect via a freeview box I would get 2 seconds of clear visual, maybe a brief bit of sound, followed by a loss of signal for about 8 seconds. This would then repeat over and over. So I purchased a more up to date freeview box which improved the situation (a new NOW TV smart box), it's now the other way round 8 seconds of clear video and only 2 seconds of loss. It's worth pointing out if I use a heftier tv box (like Virgin Media TiVo, haven't tried Sky) or my laptop. I get (almost) perfect visual. Therefore my uneducated guess is that the signal output from the lesser boxes isn't quite powerful enough to go through what I imagine to be the cheapest type of HDMI cable, or there's some sort of electrical interference. Either way I believe the cable is at fault. This will be tricky (but not impossible) to thread a new cable through the walls, but my plea for help is... Firstly do you agree that it's likely the cable. Secondly if so what cable would you recommend to truely test the theory. Thanks for your time. Paul Additional points to note: *Cable length is only 1m *There are newly installed electrical plug sockets near hole for cables *TV is old, original Philips Ambilight 1080i. (I wasn't going to mention this as this is for information only, as the original freeview box worked with this TV for years and suddenly in the new set up it didn't work at all meaningonly HDMI cable is different to original setup.
