Just bought a new LG 65" OLED. It has HDMI inputs (four of them). My fifteen year-old 73" big ugly box Mits did not. So I have never used HDMI via the Onkyo TX-SR876. FINALLY! I'll get to remove so much of the bundle of cabling between components. It's a rats nest of cables.
Took me a full day to figure out that my TX-SR876 HDMI board isn't working properly. The four inputs display "No signal" when selected and properly connected. The main output never outputs anything (including the Onkyo's on-screen setup). The Sub output occasionally does output to the TV; but not reliably. I googled and found out that "THEY ALL DO THAT" and it's a common failure of the Onkyo receiver.
Dejected, I called Onkyo. The receiver is not covered under the normal or any extended warranties. (even though the failure is apparently a design flaw). They DO have a trade-in program for a refurbished receiver. I'm in line waiting for a new "810" receiver or a new "1100". So far, the feedback on them is good.
In the interim, I've connected all of my devices to the TV using the TV's 4 HDMI input ports. The TV has an Optical output, so I routed that to the Onkyo's Optical input. With my Harmony Elite remote, it's really easy to select different devices; and all devices that have audio are processed by the Onkyo receiver via the Optical link.
So now I'm wondering: Do I really need to purchase a new receiver? The only possible reasons I can think of are
1. To get a newer unit and an extended warranty so that when IT fails, I'll have a remedy.
2. Maybe to install two ceiling speakers and see what 11.2 has to offer. (if I have the terminology right)
I'm expecting that some time in January (2017) they'll have either an "810" or "1100" come back for refurb. Then, I'll need to make the decision.
While I wouldn't be surprised if your HDMI board has failed, it very well could be a different issue entirely affecting your situation. Instead, it could be related to HDMI versioning or HDCP handshakes. The 876 only has HDMI 1.3, while your TV has HDMI 2.0. HDMI 2.0 input should
theoretically be backwards compatible to HDMI 1.3 output devices, but there's also the issue of HDCP, of which your TV supports version 2.2. And it is here where I have found some issues with my 876...
If I output my 876 to a HDMI 2.0/HDCP 2.2 display input, I get nothing. If I connect my 876 output to a 1.3 or 1.4 display input device, I get video, so the video out on the 876 isn't the issue. I do have an HDFury Integral and Linker device that may be able to circumvent these problems, but I haven't had time yet to fully test (this is not my 'main' setup) to determine if this can be fixed by placing the HDFury in between the TV and the 876.
I also have a 2016 LG 65" OLED E6 TV. If you can't find any answers elsewhere, I may be able to test your exact setup for you in a few weeks as I'll be moving some equipment around and should have better access + time to play and troubleshoot.
