Hi, I'm Nathan.Sorry to hear that you're having trouble, but I'll do my best to help you. Please give me a few moments to review your details here.
This is an online (or phone) based support service. I'm a home theater expert and installer, and would be happy to go over this with you if you'd like to do it here.
If you prefer to have someone out on site, I can help you find a local tech for that, but best buy/geek squad would not be the best choice. For check a checkup and brief training on how to use the system, most techs would charge you about $100-150 to come out and spend about an hour with you. If you'd prefer that, let me know your zip code.
