I recently upgraded my main TV from a Pioneer plasma to a Samsung KS7000 series. Unfortunately an unwelcome side effect of this upgrade is that the TV now switches to the HDR-Fox T2 input (HDMI 2) whenever it wakes up prior to making a recording. This can be very annoying if it interrupts the viewing of Live TV or another HDMI input. I tried fitting a CEC blocker (https://www.amazon.co.uk/LINDY-HDMI-Less-Adapter-Female/dp/B00DL48KVI) but this had no effect whatsoever. Any thoughts/suggestions? The TV is running the latest firmware from Samsung.
