Thank you for using Just Answer.
This remote needs to have the UPPER TOP LEFT button pushed for the TV functions to work. The button has the label "TV" on it.
Try pushing that button down for a second or two and then try the volume button.
IF this does not work we will need more information from you.
What is the TV hooked up to? (cable BOX, just cable, antenae, satellite receiver, etc..)
What type of cables are you using for this connection?
Please let me know if you need more information and/or clarification.
Thank you Bernie,
I am at my workplace right now and will try this out on my mother-in-law's tv. I should have provided you with more information. I am not that knowledgeable about the hook up, but do know that it is Fios/verizon
Let me know if you need more information. I will check back tonight and tommorow.
