I was called to a job last week with a customer experiencing issues with a TV setup. The original installer had connected one sky box to 2 avrs using a budget HDMI splitter. The Blu-ray and Apple TV was connected in the same way! After some treating it was apparent the issue was with one of the TVs connected to one of the AVRs could not display the picture it simply flicked on then off. This clearly appears to be an EDID issue and or 2 AVRs being connected together?! Any thought on a solution? We have 1x HDMI to each TV of which there are two along with a network cable and a coax.
