Robert and his son, performed the work. They were extremely efficient, polite and neat during the whole repair process. There were drawbacks but the were the fault of Samsung and not Mr. Rosano. The original parts evolved to a form factor and some of the original parts no longer fit the the original configuration. Although parts replacement was delayed, Mr Rosano never ask for any payment until the work was satisfactorily completed and his "labor cost" after 3 separate visits, was extremely fair. I could recommend any repair service more highly than Rosano's. I am happy to leave rave reveiws to Mr. Rosano. I never met Mr. Rosano and his son before they arrived at my home to perform this work, nor am I familiar with anyone who is related to, or knows him. I selected him from this web site and it was completely random. It was our good fortune to meet him as we did.
