I tried all five LG codes. No Joy.
I defaulted the 4K+ Roku stick again and tried all four Vizeo codes again. The only one that worked is the first code, but only for the first minute after starting the device, then the volume, and mute buttons stopped responding. SOMETIMES the power button would turn the TV off. Other times, no response.
Toward the end of my testing yesterday, I turned CEC off in the Vizeo TV that I have been working with (in the kitchen). Voila! It works! And it has been working almost continuously for 24 hours. I say almost because there was a brief moment when the remote failed to respond to volume commands again, but it only lasted for 15 seconds or so before returning to normal operation again.
So, for the moment, the 4K+ Roku stick in the kitchen is working normally (with CEC OFF). Unfortunately I have absolutely no confidence that this ROKU device will remain working. Remember, it worked perfectly for five weeks after it was first installed before it suddenly and without any changes it suddenly stopped responding to Volume, mute and power commands only. The identical ROKU 4K+ stick that was purchased and installed at the same time on another Vizeo TV (in the Livingroom), now roughly seven weeks ago, failed in exactly the same way a day or two after the one in the kitchen that I have been working with. More on that ROKU follows.
Since the ROKU 4K+ stick in the kitchen seems to be working normally at the moment, I spent the day working with the other identical 4K+ stick that is in use with the Living room Vizeo TV. At startup this morning, it worked fine, but only for a minute or two. The ROKU is powered by an external Apple 1 Amp USB power supply/charger. The remote showed 78% charge. I turned CEC off on the Vizeo tv (as it is in the kitchen Vizeo TV) and then power-cycled the TV and the ROKU. At power-up the remote did not respond at all. Turning CEC back on allowed the remote to work again for a minute or two only. I then spent the next several hours trying various settings, pairing the remote, setting up the remote for TV control, power-cycling the TV and the ROKU, and so on, and so on, and so on. Toward the end of my day the Voice Remote struggled several times to enter the pairing procedure after factory defaulting the Roku or “adding a new remote” procedure.
At this point, I am done spending any more time on this unless there is some new revelation that I am not aware of. I have tried every possible thing that I can think of repeatedly withe these two 4K+ Sticks and the two Vizeo TVs. I hate to think of the number of hours that I wasted researching, reading, and trying everything that I could think of or was was suggested.
I have an RMA to return the 4K+ stick that is, or was, in use in the Living room. I will wait a few more days before requesting an RMA for the other 4K+ stick that is working at the moment. I am waiting on a reply to my request to return them so that I can buy two Ultras. If that is denied or there’re is not another acceptable solution, I will scrap everything and choose different products. I will not tolerate anything that is this unstable and unreliable. We just don’t need the aggravation that they are causing us. I am happy to hear that they work so well for others. I expected the same, and had the same experience initially.
