I have a very simle set up at present using a Harmony 650. One activity - TV/Soundbar/VU Solo2. When switching off using the AllOff button, quite often the VU will remain on. I then have to go through the Help to get it to switch off.
If I do not notice it has remained on, the next time I press Watch TV the TV and Soundbar comes on and the VU switches off. I then have to use the Help button again.
I have cleared and reprogrammed a number of times but the problem persists. Any suggestions ?
