Hello ViennaVA,
Welcome to Community@Insignia™!
First of all, let me apologize for the inconveniences that this may cause.
By gathering all the information that you provided, there is one possible set up that can be changed from the Verizon Box itself.
On the Box´s menu, check for any possible option to adjust the output resolution. If there is such an option remember to set it to output the "native resolution" of the signal incoming to the Box.
For example, if the signal is being broadcasted to you in 480p, the Box has to be set up in the same resolution. If you set it up to output more resolution than the native of the signal, you are applying video processing to the signal and may cause unexpected video issues.
Also, try connecting the Box to another TV to see if you still get the same picture issue or connect another device in the same way you connected the Box to our TV.
If you cannot adjust the picture after going through this troubleshooting, what I recommend you to do is to get in contact with our authorized service provider at 1-888- BESTBUY and refer to In-Home Service.
Remember that this TV has 2 years of warranty starting from the date of purchase. In order to validate the warranty you need the proof of purchase.
Let me know if this information was useful!
If it was useful, and you liked it, Kudo it!
Thank you,
