So I have HDMI In from my Directv HD DVR to the Onkyo on HDMI3 and also use HDMI for the PC on HDMI5. The Onkyo will no longer take their signal and pass it to the HDMI Out which is my samsung LCD. Audio doesnt come through either from these sources. When I look at Info it tells me Unknown to 480p meaning it doesnt know where the input is coming from. Component from the Wii and DVD player works fine through the Onkyo and both audio and video works. The OSD form the Onkyo also works. I can also hook up optical from the Directv receiver to the onkyo and hook the directv receiver straight into the tv's hdmi2 port and it works so we know its not the Directv receiver. ditto with the PC, no longer will identify the onkyo through the nvidia control panel as available and the onkyo doesnt recognize getting a signal on HDMI5. It says RGB when I look at the info. So it appears that HDMI IN stopped working although everything else seems to work including HDMI out. I've reset the Onkyo (Standby and VCR button to clear all settings). Ive tried all the other HDMI IN ports also. Is this a tech-support call in / RMA or what am I missing?
