SooperFlye I have an older Mitsubishi TV, with HDMI, but no CEC. I have been using it that way and the my two ROKU remotes controlled the power on/off and volume of the TV very well by IR for months. This TV also has IR emitters to further control additional devices, so my ROKU remotes also controlled power and volume of my AVR through the TV. When I replaced the batteries in the remotes, the IR can no longer be programmed to the TV. You DO NOT NEED CEC! The ROKU voice remotes (Until now) used the IR emitter to control TV power and volume. That has stopped working for MANY of us since the 10.0.0 "update" (downgrade).
OK, I have a theory why this is happening to many. I have Three ROKU Ultras, the one that quit allowing TV control with the remotes is a 73" Mitsubishi WD-73833 DLP set. I was controlling TV just fine until I replaced batteries in the two remotes used on it.
Theory: I think they removed a lot of codes for older sets, the remotes hold their taught codes until batteries replaced, then the codes do not exist to re-program the remotes.
Another of my three TVs is also a Mitsubishi WD-60c9, a somewhat newer but still a pretty old DLP set. The remote used on it still works, but I am afraid that when the batteries on it's ROKU remote need replacing (won't be long, as all three ROKU Ultras were purchased and installed within a week), it too will not be programmable.
The thing that is strangest to me is that when trying to program the two remotes not working, as soon as I click on "Yes, the music is playing", it goes to "Your remote is programmed", but they do not work. I never get to "No, the music has stopped"!
If ROKU has removed the codes need to get my two Mitsubishi DLP sets working again, PUT THEM BACK!
I bought a new Roku remote which doesn't support the code that I used on my old roku remote. On my old remote (model #RC127), my acer projector could controlled using 'TV Code 5'. However, when I set my new remote (RC399) it only offers TV codes #1-#3 for the Acer projector. Is it possible to add back support for the other codes to the RC399?
Here are the details of my current set up:
