I have an Emerson, model LC320EM2 A, and I continue to gat a message "no signal." My cable provider has vigilantly checked and find no problems with their equipment. I have two of these models and the other works beautifully - as did this one until six weeks prior to this. I switched the two units and the one that is still operating as designed works well in either location. I have tried all of the on screen set-up prompts and still receive the same message, "NO SIGNAL"
