Onkyo TX-NR7100 digital snow issue

[Randy No Arms]

Update, that might help others, so I'm sharing the experience.

My Onkyo TX-NR6100 suddenly stopped support 4K@120Hz for some random reason, so I did the obvious: I did a factory reset.

Didn't work, but as I was going through the various menus, I noticed that there was a new FW update, R135-1015-0280-0033. Knew it had to be recent because it showed up after my many months of troubleshooting the eARC snowy-screen issues I was having, so I opted to install it.

FW updated without issue, but after it started back up, I still wasn't getting 120Hz, so I did another factory reset: not only was 4K@120Hz now restored but since the factory reset also turned eARC back on [on the EDID menu] I was shocked to find that it was also working, with my Apple TV and LG C3 TV.

For anyone that was having eARC issues, might be worth rolling the dice and taking the update.



For people having trouble with eARC and Onkyo's TX-NR6100 or 7100.
