webOS and Marantz Cinema 70s issues


Markus Kern

Question

I have a Marantz Cinema 70s (Version  3400-8281-E054-8790-DTS Version  3.90.50.82) and an LG G29 83"(03.33.65)which has propatly an HDMI handshake problem.

Both devices have Arc/eARC turned on/off and the HDMI cable (2.1) is connected to the ARC/eARC output on the Marantz and to the HDMI2 Arc/eARC input on the LG.

I can't get sound from the Web OS / Amazon Prime transferred to my Marantz...I have to switch manually the TV to speakers from the TV.  It can't be.
With all other devices connected to the Marantz, the sound works perfectly.

I spoken allready to the German Marantz  and also to LG Support. Marantz told me it was known that there could be a handshake problem. I should deactivate eARC on both the Marantz and the LG and then switch it back on first on the Marantz and then on the TV.

LG told me to unplug the TV for 2 minutes.

Does anyone have any ideas what I can do? Maybe I have overlooked some important settings.


thx for your help & advises in advance !

      I have an LG TV with Web OS 13.30.56 and the HBOMax app was replaced by MAX app.
      Since installing the new app I get 50+ per day ads notifications from Max app with the same add, every day , 50 notifications per day.
      I've made a video with the problem to understand it better:

      webOS updated, I think to 2023, on my C2 a couple of days ago. Since then the News option on the Sky News app no longer works, instead timing out. The Weather and Climate options still work, though.
      I have deleted and reloaded the Sky News app, but the problem remains.
      Does anybody have any suggestions of what I might try to get this working again, or is this something for LG, or Sky, to fix?

      In the specifications of this LaserTV it is shown that WebOS 6.0 should be installed on this device.
      The latest Device Firmware Version is 3.01.02 and i am missing the RTL+ App (Germany) which should be available with WebOS 6.0 
      So any info when there will be a "real" WebOS 6.0 available on the Cinebeam HU915EQE?
