Hi, thank you for reaching out. I hope you are doing well today. I understand you are having trouble with your equipment, and you are getting the error code 340 on your television. I know how frustrating service issues can be, and I can surely do my best to help. Can you tell me about any troubleshooting you've done so far? Have you attempted to reset your equipment using the Xfinity App, which you can read about here https://www.xfinity.com/support/articles/x1-reboot-my-set-top-box?
