Code
my z11 pro max which is connected to a denon amplifier has started to exit mytvonline3 after 4-5 minutes, it starts by going into search mode then it ends up on the home menu & it lowers all the sound at the same time on the box, not the amplifier. then it starts youtube without sound. all by itself. sometimes it starts adding rows of favorites on the home menu. I have disconnected the remote, removed the batteries & connected the control again, still the same everything started yesterday, previously it has flashed in white, one to two seconds later landed in the menu mode. if I start mytv3 again the picture is back again immediately, it can take 1-2 hours between these white flashes. but now it is worse as it behaves as I described at the beginning. does anyone have any tips.. would rather not do a factory reset, because of all the tv and films shows we have saved.
