I'm not sure its the right place but at any case i will describe my issue here and maybe you will be able to help:
Recently I bought a a TV and a sound bar, and i have some issue from the moment i get the TV.
TV model - LG 55LB679Y with latest firmware version i have at my country (Israel) - 04.30.16
SoundBar - LG NB4540
the TV connected to sound bar by "wireless simplink" feature 'LG TV' and TV connected to My Wireless router.
every 5 - 15 minutes, i have sound drops / Cutoff / stooped / Interruption, seem like the TV loose connection to sound-bar for few seconds or something similar, it's happen from any AV source im using HDMI, USB...
and the local re-seller replace the sound-bar to a new one (same modal off course) and i didn't help.
i have try to troubleshot the problem in the last few weeks - but didn't succeed to solve it, and also the support / costumer service didn't have solution for this.
some steps i take when troubleshot this issue:
* different wireless configuration on router - different channels, SSID, Security - issue still persist.
* another wireless router - issue still persist.
* working with optical cable to sound bar - just for testing - working ok, but i need the wireless feature working this the reason i bought sound bar and TV from the same manufacturer.
* disconnect the TV from wireless network - looks like it's working ok, but didn't had chance to test it for long time.
from my point of view looks like it's issue with wireless device on TV not able to to work in parallel with soundbar and wireless network for some reason, It could be caused bysoftware issue on WebOS or Hardware issue with this TV model.
I really hope you be able to help me or throw some light on this case.
I have an Onkyo TX-NR6050 connected to a LG OLED77C2PUA using a high speed HDMI cable.
When the TV is tuned on the Onkyo comes out of stand-by mode. The volume control on the LG remote is able to raise and lower volume control on the receiver. The LG has a connection to the Onkyo but the LG is not passing any data.
If the receiver is out of stand by mode (by either turning the receiver on first or turning the TV on --> off --> on) then there is a data connection and sound can be heard.
The issue seems to be in the timing of the handshake between the two devices. The LG has no problem turning on the onkyo but whether the data connection is established is based on the receiver being out of stand by mode first.
I tried everything found on line from changing HDMI connection type form Auto, PCM, and pass through. I have tried disabling the quick start from LG setup.
It is very annoying considering the amount of money invested into a setup that is suppose to be eARC 2.1. I should not have to use the home theater remote.
