Isaac and his assistant arrived on time. They checked my 75" LG Flatscreen TV and determined the motherboard and wifi card were not functioning properly, thus causing the wifi signal to drop and the inability to access specific apps. They installed a new motherboard and wifi card which solved the problem. After the parts were installed, they reprogrammed the TV and answered all my questions. They arrived on time and were extremely respectful of my home; they removed their shoes and were extremely careful in removing the TV from the wall and re-hanging it. Isaac was extremely professional, knowledgable, and personable. His ability to isolate and fix the problem was outstanding. I would definitely have Isaac back for any of my electronic or security needs. I highly recommend Isaac to anyone experiencing electronics or security equipment issues, or need professional installation of electronic or security equipment. read more
