Your problem requires an onsite technician to evaluate what is happening. The purpose of this forum is to help with user related questions. I would advise that you request a "vendor meet", which is getting the service provider and telephone dealer at your property at the same time. If you are unhappy with your dealer you can use the "find an installer" link at the top of this page. You may also contact Samsung directly. The system you have in is an excellent piece of equipment which I doubt needs to be replaced.

BTW, most of the people you are talking to on this board are dealers.
