I have an Vizio HDTV in my exercise room which I use to watch an analog signal. My provider is Comcast and they have given me a small box to convert their digital signal to an analog signal. The connection from their box to my TV is a coaxial cable. I have verified that the coaxial input on the TV no longer works, but the HDMI inputs are OK. I could just buy a new TV for less than $200 on Black Friday, but it seems a waste to dispose of a working TV. Is there any cheap converter that will take the analog signal and convert it back to digital on HDMI?
