I moved into house and have had FREE cable for years. Cable comes off of the line into the house and plugs directly into TV. I do not have any decoder or cable boxes from the cable company. I still have an older flat screen that works and changes channels quickly. It is a 2009 Model Samsung 40" 1080p LCD HDTV w/ Touch of Color Design - LN40B550 My other TV went out and bought a new TV only to discover that it took 3–5 seconds to change channels. I purchased a Brand New Sharp - AQUOS - 60" Class (60" Diag.) - LED - 1080p - 120Hz - HDTV Is there a specific TV that I can purchase that will work as well as my older TV? Or is there a product that I can purchase to speed things up?
