A:Answer 1: The answer to the question is: yes, if you connect this device's RCA out cables to your TV's RCA input jacks.
2. This device converts HDMI to composite (RCA connector), meaning that you feed this device an HDMI signal, and it converts it to composite signal (RCA), for feeding into your old TV. It does not convert going the other way. It won't convert composite (RCA) to HDMI. I believe Insignia has another device that does that.
3. So regarding the answer by By Deely 4 months ago, He wrote: " But I had an old DVD player with RCA plugs. This device allowed me yo use the DVD player with my new TV. " : He must have been using a different Insignia device, not this device.
This device will NOT convert RCA output from a DVD player to HDMI for feeding into a HDMI TV. I believe Insignia has another device that does that.
4. Regarding answer by Charles V. InsigniaCustomerSupport 4 months ago, he states "It also allows the usage of Digital Optical Cable for surround sound systems." I don't know what he means by that. This device does not have any connector/cable for Digital Optical Cable. The composite output of this device is analog, not digital.
Hope this helps.
