My tv is having a problem where the inputs are not recognized. I currently have two inputs set up via HDNI and another two set up via component cables. At times I will try each and every input and they will not show a picture and say "searching for a picture"! I have tried using various cables and nothing works. Does anyone know what causes this?Its getting worse and Samsung will not do anything because its out of warranty. However they fixed the white dot problem I have out of warranty! I dont know why they pick and choose what they will do extra to make a consumer happy. Right now with all the problems I have had with this tv that I would never purchase another Samsung product. Why is it that I can never speak to an full blown american when I call? Even the supervisors are forign and I have such a difficult time understanding them.
