Issue
Whenever I start any video—whether it’s streaming apps, HDMI input, or a USB movie—the SC9S plays for a minute or two, then suddenly loses connection. Audio instantly falls back to the TV’s internal speakers, and the TV acts like the soundbar no longer exists on the eARC port. The soundbar display still shows “eARC” (sometimes flips to “OPT/ARC” for a second), but no sound.
Temporary Fix
The only thing that gets audio back is power-cycling the TV (standby isn’t enough; full reboot required). After that, the bar reconnects… until the next random dropout. This can happen multiple times during a single movie, which is a great way to kill the vibe.
What I’ve Tried
New HDMI 2.1-certified cable (same result, so original cable seems fine).
Disabled Quick Start+ and Simplink in the TV settings, then re-enabled.
Factory-reset both TV and soundbar.
Tested ARC instead of eARC—works, but no Atmos and same occasional dropout.
Plugged the soundbar into a different power outlet (in case of power spike).
Observed Patterns
Dropouts happen sooner with Dolby Atmos or DTS content, but even stereo YouTube videos eventually cut out.
No obvious heat buildup; bar is in open air, front facing.
Happens whether soundbar is wall-mounted or on its stand.
Questions for the Hive Mind
Anyone else seeing eARC instability with the SC9S on the UP77 series?
Could this be a handshake timing bug on the TV’s HDMI board?
Any hidden service-menu tweaks or firmware betas worth trying?
Should I just RMA the bar, or is the TV the real diva here?
Appreciate any insight—my couch and I thank you in advance!

My 65UQ70 TV started to ignore my remote yesterday. After some experiments I've found that it only reacts to double clicks now. So I have to use double clicks for any action - move through menus, launch apps etc, single clicks are just ignored.
Resetting the TV to factory settings didn't help.
I tried to google the issue and found that this might be an issue with the remote, but I can't find how to reset the remote of my model. Combinations like Home+Back (for Magic Remote) or 2+8 (for some old style remotes) don't work for my model, neither removing batteries and pressing all buttons does.
My remote seems to be AKB76040302, a photo from the Internet is below.
So, how do I reset it?
Some other things to mention:
- The pulses of the remote are not visible through a cell phone camera, so I couldn't check if it only sends signals to the TV after double clicks, or the TV is enforcing this issue. UPDATE: a cellphone sees the pulses in darkness, and a pulse is sent on each press, not only on doubles. So it should be TV OS issue, not the remote issue.
- This started to happen after I have updated the software and connected a sound bar with optical cable, though I believe the last action isn't related to the issue.

Consortium’s Real-World Labs in Anchorage and Fairbanks
Aim to Optimize Heat Pump Performance in Tundra Conditions
ANCHORAGE, Alaska, Dec. 12, 2024 — The Consortium for Advanced Heat Pump Research, the groundbreaking partnership between LG and the University of Alaska Anchorage (UAA), has opened state-of-the-art, real-world-simulated labs to conduct comprehensive studies on cold-climate heat pump HVAC solutions.
LG and university researchers will conduct studies in two dedicated cold climate heat pump labs located in Anchorage and Fairbanks. These facilities are configured to replicate home environments, enabling a realistic and practical approach to heat pump research. The labs will utilize a variety of LG’s cutting-edge HVAC solutions, including both ducted and duct-free indoor and outdoor units, to assist in the research.
The work of the Consortium for Advanced Heat Pump Research exemplifies Alaska Governor Mike Dunleavy’s focus on nurturing impactful technology initiatives built on strong public-private partnerships. “Together, researchers from the University of Alaska Anchorage and global innovator LG Electronics are advancing the state of the art in heat pump technology,” the governor said. “These advanced research labs show how new business and investment in Alaska can have a major impact on our nation and the world.”
“Heat pump technology is integral to HVAC-related decarbonization efforts, and the research conducted at these new labs will help to further drive progress,” said Chris Ahn, president of LG Eco Solutions USA. “This research into advancing progress in heat pump system technology supports the promotion of clean energy advances that are among the primary targets for IRA (Inflation Reduction Act) funding in most states, including those in colder climates.”
The Cold Climate Heat Pump Labs in Alaska will leverage LG’s cutting-edge heat pump technology to deliver region-specific comfort solutions designed to reduce dependence on fossil-fuel secondary heating sources.

Question
李紫玲
I highly enjoy the time shift function still works when I open YouTube app and return to live TV, so I can skip back in time and jump over commercials.
However, of no apparent reasons, (no firmware upgrade) time shift got cleared to zero (like just turn on) after I start youtube and close it to return to Live TV. Time shift also got cleared after switching to HDMI and return.
Does your tv behave the same?
