A:AnswerThis remote has likely not been tested with your specific model of Dynex TV but it will likely be able to program over. Keep in mind that Best Buy does have a 15 day return period that would allow you to return the remote if it does not program or you are not satisfied.
A:AnswerI'm assuming you purchased a Insignia T.V. If that is the case then the answer is no. You will get a standard Insignia remote that works only for the t.v. or whatever Insignia product you bought.
A:AnswerAccording to my memory, it either work with my Insignia TV immediately or the first code I found worked. Now, my TV was bought around 2012-2013.
A:AnswerI used the Insignia remote NS-RMT415's "STREAM" button to link it to my soundbar; however, that was not until I contacted Insignia tech support at 1-877-467-4289 between the hours of 8:00 A.M. and 9:00 P.M. "7" days per week for some detailed guidance with this issue. Please keep in mind that if you go on the website Insigniaproducts.com and enter this product's model number (NS-RMT415) in the search bar and then click "Supports & Download" and then click the "Quick Set Up Guide" you can secure further remote control operation knowledge.
