No video/audio being outputted
First troubleshooting question is: Are you using the converter with the source device’s HDMI video output set to 1080i, not 1080p?
The digital to analogue processor (DAC) cannot accomodate a 1080p input signal. The component converter is 1080i pass-through conversion to component video device – it cannot actively reconfigure a 1080p input signal to 1080i.
This is stated on the website, but some people miss it. “The HDMI to Component Converter is a Digital to Analogue (DAC) conversion device that will take a HDMI source input (up to 1080i) and output the video signal as RGB component (YPbPr).”
Finally, always power on the system in the following order from an ‘off at the wall’ starting point.
