r/Onkyo

I bought a TX-RZ30 about 3 months ago. In that time I have had to factory reset it 3 or 4 times to get the WiFi to come back alive. Recently, even the Bluetooth is proving unreliable. I can only get the app to work for about 5 days before the WiFi craps out. Which means I can’t change the Dirac profile once the WiFi is dead. Sometimes it takes an hour to get it working via the crap menus. Sometimes I factory reset the unit and have to start from scratch.

Am I the only one? Did I get a lemon? Or is this the least reliable wireless device of the last 20 years?

My home theatre started to malfunction. I clicked to select the BD/DVD input. Then it selected FM or another input, same happen with the Power button. I have to keep pressing the input I want a few times until it is correctly selected. The remote control works fine.

Is there something I can do to fix this?
I have some experience of working with electronics and fixing my own things, but none with Onkyo equipment.

Thanks.

I swapped out of my old and beloved Marantz SR5012 for my home theater to this newer TX-RZ30 because of specifically 2 reasons: eARC and Dirac Live.

Now eARC is so finicky i want to throw this AVR at the wall!

My RZ30 is paired with my Sony Bravia 8 II QD-OLED and I can get eARC to work but then it'll stop working randomly sometimes within the same sitting session if say I walk away from watching YT for a bit and come back, now the next vid won't have sound. It'll come back on if i fidddle with the Sony Audio settings again to turn off arc and then back on 50% of the time. Sometimes when I turn on the TV the next day it's broken again and I have no sound. It's more problematic than a 2 year old child!

I've gone through the guides , I've used 2 different sets of high end cables. It will work, but it never stays working for long.

What gives Onkyo!? I loved your products in the past.

Any help appreciated!

Onkyo TX-NR656 Handshake Issue: Stuck in "DVI" Mode with RTX 40-series/50-series - Resets not working

I am at my limit with this Onkyo TX-NR656 and need expert input. I am running a high-end setup with an RTX 4080 and an RTX 5070 Ti, but the receiver is stuck in a legacy handshake loop. Even though I have managed to get 4K resolutions to show up in the NVIDIA Control Panel, the connector type is still stubbornly labeled as "DVI - PC display." My cable management is extremely complex, with wires zip-tied and routed through a drop ceiling, so rerouting everything is not an option.

Before suggesting the basics, please note that I have already bypassed the HDMI switch and plugged the PC directly into the receiver with no change. I have performed the official "Clear" factory reset using the CBL/SAT + ON/STANDBY combo multiple times. I have also tried a full power drain by leaving the unit unplugged for an extended period. In the NVIDIA Control Panel, I have attempted forced resolution changes and hot-swapping the HDMI cable while the system was live to force a re-detection. I also tried the BD/DVD + ON/STANDBY combo to toggle 4K Enhanced mode, but the front panel did not respond to that specific command.

The hardware is clearly capable because plugging the PC directly into the TV works perfectly as HDMI, so the Onkyo is definitely the bottleneck. It appears the HDMI board is failing to broadcast the correct HDMI identifier (EDID) and is defaulting to a legacy DVI signal instead. I have already spent hours on this and am not looking for beginner troubleshooting or "try a different cable" advice. Does anyone know a way to force this specific model's HDMI board to stop lying to the PC, or is the board officially a lost cause?
