Using Alexa with Verizon Fios and Sony TV - Issues changing channels

[RLQ]

Does anyone have any best practices when using Alexa for both Verizon Fios (or any other cable provider) and a Sony/LG TV? I am finding Alexa has trouble when you say "Change channel to ESPN" because its unclear whether to use the TV or the cable (FiOS) to do so. Is there any way to clarify which device to use?

Seems like a trigger such as "Alexa, use FiOS..." might be helpful to correct this?  Any other ideas?

What I have found is that it is best for Alexa to use the name of the skill in any command.
