I’m having a bizarre issue with my home theatre setup, I used the harmony one with this system for several years and the issue just started happening after I moved to my new house, I didn’t change absolutely anything in the system as far as adding a new component or modifying the settings on my harmony one remote whatsoever..
I use my EC9300 OLED TV’s built in channel tuner to get local hd channels using a QAM tuner, I get about 5 hd local channels which is good enough for me but the tuner also found a whole bunch of other crappy and non functional channels During the channel scan but It used to be a non issue as I just watched any one of the 5 local hd channels that I care about and would never manually switch to the non functional channels so it was never an issue but the issue I’m having right now is that when the entire home theatre system is off and I click “ Watch hdtv” activity on my harmony one, as the activity is started and the tv and my avr are turned on and the proper inputs are selected, there seems to be another command being sent out by the harmony to the tv which CHANGES the channel to some random channel (a non functional channel that isn’t even working) and i then need to switch back to one of the 5 hd channels I actually want to watch and this happens every time I start up the system. I looked up the startup sequence in the harmony software and it’s straightforward there (as I expected because I haven’t changed anything), the harmony one is programmed to turn on and send “TV” input command to the lg OLED tv to set it to tv mode and the avr to the proper input,
What could possibly be causing this? If I start the system using a different activity such as “Watch Apple TV” and if I do “Watch HDTV “ from there the random channel change does not occur, It it only when I start up the system using the watch hdtv activity.
I’m clueless as to what’s causing this, the only way i have found to combat this issue so far is to manually Add an extra command of “channelPrev” to the watch hdtv activity in order to basically switch back to the proper functioning tv channel once the tv is turned on and that random channel switch occurs.
When I watch hdtv, and I turn off the system, the next time I turn on the system the same channel should be on screen but the darn harmony remote SWITCHES the channel to some random non functional channel from the TV guide lineup and I need to manually switch back to one of the 5 channels I want to watch. This is absurd. I tried deleting these non functional channels from the lineup of channels in Lg’s channel settings page but they don’t allow it.
When I turn on the system using the tv’s original remote this problem doesn’t occur so it’s not a problem with the tv, I bought a harmony 950 (Which is basically a harmony elite minus the hub) as well thinking my harmony one was perhaps defective but the harmony 950 does the exact same thing upon “Watch Hdtv” activity startup. (I migrated my harmony settings entirely from the harmony one to the 950)
I’ve I tried placing my hand in front of the harmony remote right towards the end of the Watch TV Start Activity Sequence after it turned on the tv and avr and the proper inputs were set and the random channel switch does NOT occour so I know for certain that some signal is sent out from the harmony to the LG oled tv that causes it to change to some random non functional channel and it’s driving me insane. I tried deleting the watch hdtv activity in the myharmony computer software and re creating the watch hdtv activity from scratch and the same issue occurs, I did not try deleting the ec9300 OLED tv from the devices menu and re adding the tv to the devices menu.
The startup sequence of the Watch HDTv activity is as simple as it gets
“turn OLED TV On
turn Onkyo AVR On
Set LG OLED Tv to “TV”
Set AVR to CBL/Sat”
I manually added a “ChannelPrev” command to the end of that sequence now to combat this insane issue I’m having so that at least when the tv changes to the random channel on startup the “ChannelPrev” command basically forces the tv to go back to the channel that it turned on with in the first place which would have been one of the desired 5 local hd channels that I’m watching on a normal basis
“Simplink” is turned off on the LG OLED TV and HDMI control (CEC) is turned off on the Onkyo NR818 AVR, that was one the first things i suspected to check for when I first noticed the issue. I'm clueless at this point and id be greatly appreciated if someone can help me
