Bob, You fail to mention the model of your Yamaha. It needs to have an eArc HDMI port and you need to use a highspeed HDMI cable. Your cable box (you should dump it for YouTube TV), AppleTV and Blu-ray player should all be plugged into the A/V receiver with good HDMI cables. If your current Yamaha is 5 years old or older, I suspect it lacks eArc with HDMI highspeed cabling. You purchased the best TV. Unfortunately, you didn't do your homework before the installation. Most manufacturers don't play well together. High-end A/V is complicated and requires study beyond most manuals. Best of luck to you! T R Black

Fab, You are welcome. Thank you for providing more info. I know nothing of the Harmony Hub. If it works for you, then good. I might remind you that ALL these devices are now computers. It is kind of amazing that they "play nice" with each other as it is. And, firmware seems to "upgrade" without warning. Interfaces can change over night. Regarding the Onkyo - refer to page 115 of your owner's manual at the upper left: 5. Hardware 1. HDMI Change the settings of the HDMI function. HDMI CEC (Default Value: On) Setting this to "On" enables the input selection link and other link functions with HDMI-connected CEC-compatible device. When this setting is changed, turn off and then on again the power of all connected devices. • Depending on the TV to use, a link setting may be required on the TV. • This function is effective only when the device is connected to the HDMI OUT MAIN jack. • Setting this to "On" and closing the operation screen will display the name of the connected CEC-compatible device and "CEC On" on the main unit’s display. • When this function is set to "On", the power consumption in standby state increases, however, the increase in power consumption is minimized by automatically entering the HYBRID STANDBY mode where only the essential circuits operate. • If you operate the MASTER VOLUME dial on the main unit when this setting is "On" and audio is output from the TV speakers, audio will be output also from the speakers connected to this unit. To output audio from only either of them, change the setting of this unit or TV, or reduce the volume of this unit. • If abnormal behavior is observed when this is set to "On", set it to "Off". • If a connected device is not CEC-compatible, or if you are not sure whether it is compatible, set it to "Off". On When this function is used Off When this function is not used. Check to see if your setting is in default/ON. If it is, turn it off and see if that helps. Regarding the LG C2, I noticed the same issue, having set-up all the apps on the LG without need of AppleTV, a Firestick, etc. The default seemed to go to the screen you describe "home dashboard". However, since my client had a couple of devices she used from time to time, she doesn't mind hitting the "home" button of the LG Magic Remote to see her apps at the bottom. It is slightly disorienting at first, but I think your wife can adjust pretty readily. On my system, with a C1, like I said, I run all devices through the Denon receiver. Thus, when I turn on the LG, it immediately shows whatever device that is selected on my Denon, which is usually AppleTV. So, I see the beautiful Apple 4K scenic screen savors for my opening screen. The bottom line is: do not expect perfection from any device. Design your system (with all app preferences and hardware) set to your utmost liking as possible. Then, orient yourself (and your wife) to that paradigm and be happy with what an awesome AV system you own. Enjoy the heck out of it. And, be prepared for changes and shifts within the firmware and app updates. Some may be great, some, not so great. Life is complicated and so are AV systems. The better the system, the more complex, the more attention is needed by the consumer. Expecting to set it up and forget it won't cut it anymore. I doubt you want to go back to the era in which I grew-up: a TV with an on-off button, a dial that found 3 channels, if the antenna on the roof was positioned correctly. It was simple and required no further action once the antenna was set. But, I don't want to return to that era. Do you? I hope you truly take the time to really enjoy your "fabulous" home entertainment system You did good! Mr. Black p.s. both of my subwoofers have been on for over 3-and-a-half years without interruption.

Not being able to examine your set-up directly, I can't answer with any specifics. I did read the manual for your Onkyo model. It is a bit iffy regarding ARC and eARC. My experience is that using ARC can be flaky. When I had ARC equipment, I used the digital/optical output of the TV to the optical input on the receiver. The limitation is 5.1 audio out., but it always worked correctly. I have had zero problems using Denon receivers equipped with eARC and your model of LG TV (I just did an install in Oregon last month featuring a 77" C2). With eARC, I always use an ultra hi-speed, 48Gbps cable. I mostly install full 7.2.4 Atmos systems, but this method should work fine for 7.1 and 5.1 applications, as well. In your case, I can only suggest checking the use of CEC (possibly by default) on either your TV or receiver and making sure that you have a hi-speed cable from eARC to eARC HDMI ports and that the LG is set to eARC. If you double check everything I mention and you still have a problem, you might contact Onkyo to see if there is a compatibility issue with LG TVs (there shouldn't be ... you purchased the best value in TV ...Samsung is behind LG in the food chain). I have a C1 and C2 77" OLEDs and experience zero problems with sound, or vision and I have 5 devices using up all the available HDMI ports on my Denon. Full Atmos in and out. Finally, make sure your firmware is up-to-date on both your receiver and TV. I know this stuff can be VERY frustrating when it doesn't perform as expected. Keep plugging. I hope you find that it is a simple fix. Best of luck! Mr. Black

My advice, with decades of experience: Do not let any device control another device. NEVER turn off your receiver or any other device attached to the receiver (AppleTV, disc player, whatever). ONLY turn the LG TV on and off.

I am on my third LG big screen since 2017...all excellent, especially the new 77" OLED-CX. NONE allow the HBO MAX app (nor HBO GO, etc. previously). So, I purchased a 4K Dolby Vision Firestick (for HBO GO in January 2019). Worked well. Then, HBO says, "No GO, only MAX." Firestick says, "No GO for MAX." WTF? After chatting with HBO customer service for nearly an hour, we realize there are "corporate complications." With MAX struggling to launch, Firestick was allowed to keep GO going until they could handle MAX. In the meantime, I still wanted MAX and all the extras for the same price as GO. So, I choked hard and purchased an AppleTV 4K 8GB Dolby Vision unit. I hate Apple, but, I have got to admit, it is sweeter and smoother than the Firestick, with a much more elegant interface. Both units want to sell you shit, but you can mentally filter that out. I watch on the AppleTV (you get the AppleTV+ streaming service free for a year...Ted Lasso is FUN! - other good shows, too). Of course, six months after buying the Apple, Amazon worked out things with HBO/Warner and now the Firestick accommodates the MAX app. I still prefer the Apple experience (and I wish I didn't). Note: I have ALL the streaming services and HBO is still the king of the premium TV series. However, all those great legacy shows (available both a cable subscription (ick) and from MAX (GO had 'em, too) are in HD - 5.1 ONLY. Fine looking and sounding, but old news. With HBO MAX, they are taking it to the MAX - new movies and shows are in Dolby Vision and Dolby Atmos. Compressed, yes, but it shan't be too long before we get uncompressed streams (maybe at a higher price). If you have a system like mine (13 discreet audio channels/amps/speakers), properly placed and set-up...with uncompressed DV & DA, no current movie theatre competes, as they have to entertain hundreds of guests, compromising their systems. I have seen hundreds of films on a real IMAX (Irvine/LA) and full-blown Dolby Theatre (best all-around - IMAX* has harsh, Klipsch-like horns, poorly placed.). They just can't compete with an OLED Big Screen and high-end home audio. Thus, if you really want HBO MAX (and you won't regret it), and you can afford the AppleTV, get it. Else, wait until the next Prime Day (if you have Amazon Prime), and get the 4K DV Firestick on the cheap. *Visually, films shot in IMAX 70 mm on IMAX cameras (especially 3D like Polar Express), are second to none (Nolan had his own techs set-up and run Dunkirk on the Irvine, CA IMAX - OMG!)

Get an Amazon Firestick to download all your apps and quit whining.

Purchase an Amazon Firestick TV and place it in one of the available HDMI ports.

Hi, I solved this issue by simply purchasing an Amazon Firestick 4K. While it doesn't support Dolby Atmos* on Netflix, it does on some Prime selections. It supports Dolby Vision*, too (like your OLED) and it works seamlessly. It has nearly unlimited apps available, including HBO NOW, and has twice as much storage (for apps) than your LG TV. I like mine so much, I purchased a second one on Prime Day at half price for my road trips. Once you register it with Amazon, you can stick it in any TV with an HDMI input. Hope this helps! Mr. Black * HBO currently only streams in HD 5.1, so this is not an issue for your question
