Thank you! I finally tried the GE codes and it worked!!!
I tried GE code 1 per suggestion, answered that music stopped (when it didn't stop) and just volume up/down, mute/unmute worked. TV on/off doesn't work. I tried other GE codes - they didn't work at all.
I was going crazy. I've never had this problem. Came across this forum, none of the other codes were working . Not even for LG. And then I saw your comment and youre a genius. Worked like a charm. Thank you
