Hi there. I've recently purchased the Onn 4K Android TV box from Walmart and, so far, it has been great.
But since i've bought it, i've been trying to setup the remote to work with my JVC TV (LT32N750U), but none of the codes seem to work with it (i had tried many times).
So, i suposed the HDMI-CEC will serve as a second option, but doesn't seem to be fully functional: the only command that seems to work is when i turn-off the Onn box (it sends the signal to the TV and it turns off too after a couple of seconds). As to the volume and input commands, they don't work at all (btw, the CEC settings are all activated, both on the Onn device and on the TV as well).
So, by now, i'm trying to get a brand code (any) that could work with this TV model, but searching one by one on the Android TV list seems like could took forever.
Any help will be really appreciated. Thanks!

Try that and if not, report the issue to Walmart and they might fix it. Not all TVs can be supported so you may have to use your phone as a remote until you buy a new tv. People also say that the old FireTV remote works as a replacement remote if you lose the Onn remote.
