I bought a HDMI matrix to make life easier in my new home. I have a 4x4 and currently have 3 tv's output and PS3/Sky as inputs. 2 out of the 3 TV's are fine and fully function with IR over HDMI but the kitchen TV is struggling and the issue has worsened over the last 3 months for what I believe is no reason? I used to be able to use the sky remote on the IR over HDMI and that function has gone, now the picture is hit and miss, sometimes turning green and dissapearing and also have random sound outtages of about 2 seconds. This can be very frustrating. Currently I have the IR over HDMI connection plugged in and also an elbow connection as the wall mount is low profile. Is the fact I have 2 further connections before it enters the TV weakening it? All the HDMi cables are in the wall and papered over so relacing would be the last thing on my mind as I still have my bathrooms to do yet Any advice/help appreciated. Thanks in advance!
