Mine stopped working one day and couldnt figure out why it wouldnt connect with all 50 codes just came across this and searched my rca as an LG and the second code worked I can finally control my TV again thanks so much!
I've tried everything: all rca codes, all lg codes, nothing. All it does is mute the tv at one of the codes but never stops playing the music. I haven't been able to control the volume from my new remote i got with the stick at all
The setup process, which relies on the remote control mute signal, doesn’t work for all TVs, even though power and volume will work.
Try selecting “yes the music stopped” on the first, second, it third code attempt, and rest power/volume after each. The should work for most modern TVs. My 2010 LG worked for power and volume on the second code.
