A:Answer Hello, AGL,
This converter box was designed to convert digital signal from over-the-air channels into an analog signal so you can continue using a digital antenna on older TVs that does not have a digital tuner. In this case I would recommend to try the NS-HZ331, which let you convert signal from an HDMI device, an provides an analog output through RCA/AV jacks. Please contact the TV manufacture to ensure it has the appropriate RCA/AV input so you can use it on your TV. You can also follow the link at the end to contact us and we are going to do our best to assist you.
