Hi All, I have an Onkyo TX-SR606. I've already had the issues this model carries with the capacitors and have successfully replaced the capacitors. All HDMI inputs now work when I hook the cable box up to them. The input is HDMI from cable box to receiver and output is HDMI from receiver to TV. The problem is that when I unplug the end of the HDMI from the cable box and plug it into the ATV... I get nothing. No sound, no video... nada. If I go straight form ATV to TV, everything works fine. I've tried all cables in all positions and results are the same. Any suggestions or hints or commiseration would be appreciated.
