Hello, What device are you asking about here today?
I only see a general question about a remote, but not sure what that remote goes to?
Thanks. The way to sync the Harmony is through your Harmony account, however are you saying the 900 will only turn the TV ON?
If so, what other functions are you trying to access on the TV (for example: Channels would generally be through the cable box, and Sound could be through the TV or through an external AV system)?
That's why I'm asking you for as much information as you can give me since I am not there to see what you have.
Hi there and welcome
This is another expert here. Do you still require asistance with this? If so, tell me the make and model of the TV or unit it is not controlling correctly please
