In regards to voiding your warranty... As far as I know there aren't any VOID seals on these LG OLED's, i.e., seals that need to be broken to access the components (at least there weren't any on my B6
) Whenever I suggest opening a TV, receiver, computer, etc in a repair attempt... I like to add the warning to my posts as a disclaimer, if nothing else to dissuade a well meaning individual from butchering or destroying a product that could still be repaired under warranty. As you might guess, some well meaning owners are eager to try... but they don't know the difference between a Phillips screw and a Torx and chew the hardware up so bad any authorized technician would be able to identify the set had been tampered with. That said... based on your comment "I've taken apart many electronic items over the years" and if you have all the proper tools... removing the back cover is actually pretty easy.
In the meantime (and before a disassembly attempt) I thought of a couple more things to try. This first one is a long shot
attempt but what the heck:
1) Connect your TV to your network via a "Wired" connection and leave it connected.
2) Go to the LG settings menu on your TV and make sure it shows "Wired Connection Ethernet - Connected"
3) Go the LG General Setting menu and "turn off" quick start.
4) Turn off your TV, then unplug the power cord for at least a minute.
5) Power down your network router (to prevent your C6 from connecting or making a WiFi connection attempt)
6) Plug your TV back in and power it up.
7) Power your router back up
(The idea is... with quick start turned off its possible your set may not attempt to connect via WiFi if it first detects the wired connection
If that didn't fix the issue... another thing to try would be a Factory Reset. Why? - When these sets are powered on, new out of the box, LG takes you though the initial setup. At one point you are asked if you will connect the network via Wired or WiFi. If you select WiFi and have a secure network you are prompted for the password. With earlier LG TVs, through 2014 anyway... if you selected Wired during the initial setup... it stopped the WiFi connection attempt! ( the wireless circuit was not turned on.) What I don't know, is what options are offered to the user after selecting "factory reset" from the user settings menu. I'm not sure if it takes you through the entire setup again but am hoping you will be prompted to select your network type again. (NOTE: Be sure to record your color, brightness, contrast, settings etc, before doing the reset)
Justification for the above "Reset" approach? - What I can tell you for a fact is... I just conducted a test.
When I first installed my B6... I was hard wired and selected Wired
. Today... if go into Network settings it shows Wired Connection (Etherenet) - Connected... and WiFi Connection - Not Connected. So... as a test 10 minutes ago, I unplugged the wired connection to my set. Then when I checked the menu both Wired and WiFi show - Not Connected. I then clicked on WiFi Connection... and it said "No Networks Available... even though I have a very strong Wifi signal via my NetGear dualband R7000. (This is in addition three other networks belonging to my neighbors WiFI devices always pick up.) To me this indicates my B6 is not polling... just like the 2014 sets selecting Wired during the initial setup seems to disable / turn off the WiFi circuit. This in fact may be how Hotels avoid having it turned on!
In regards to your questions about the service menu and hotel settings and the locations of the Bluetooth receiver and a simple IR receiver... give me 10 minutes or so and I'll be sending you a PM with more information.
