Question about Insignia NS-LCD37 37 in. LCD TV
Try going to the initial setup menu to check if the unit is set to the correct input. It may have been an internal glitch that has fussed with the 'source' so that it is looking at something other than the cable input which may be called 'Tuner.' If the setting is correct, then the input conditioning which may be on a smaller board, or part of the main board may have failed. As an experiment, use another input with a camera, camcorder, DVR or VCR and set the source accordingly. If none of them work, your set is definitely sick.
