Question: Please answer in "Senior-speak": trying to connect a new Blu-ray Disk Player to a great old TV with yel/red/wh plugs.  Do I need some kind of cable?
Document: It's been about a month now and this works awesome. I have an old style non HDTV and wanted to get rid of cable. I bought a new sony blu ray player and it has built in wi-fi and it only has an hdmi output on it. I bought this convertor and connected it to the rf modulator and blu ray and it works perfectly. Better picture quality than cable. I needed the rf modulator because my tv is so old it only has one input which is a coax connector.
I purchased this to connect a DVD player, that only had HDMI out, to a old CRT TV. I couldn't find a DVD player with RVC out, and I didn't want to invest in a new TV at this time, so I though I would give this a try.I hooked it up and it works like a charm. It did not require the included USB cable to power it. The picture quality is at least as good as the cable box that is also hooked to this TV.
I purchased this product to display my tablet on an older tv without an hdmi input. I had my doubts because it wasnt a typical connection from a blu ray player. It worked great! My tablet screen is broken and i almost threw it away. Im so glad i didn't. Instead of buying a new led tv, this converter was my solution to viewing my tablet again! Would highly recommend
Rather than comparing it to putting your TV on steroids, it's more closely compared to putting your new digital output on ridlin.To power the device, I actually took the USB cord (supplied with the device) and plugged it from the white MINI into the USB port of the very same Blu-Ray player that feeds the HDMI stream.
I've been using this for a month or so to send a signal from my Samsung Wi-Fi blu-ray player to an old tube-TV from the 90's, mainly  so that I can watch Netflix. Works the same with or without the USB power supply.Only reason I can't give it 5 stars is because it has one glitch.
I needed this to connect a Blu Ray player that only had a HDMI output to an older TV without one. I first tested on my own set with both inputs. The image via the adapter was quite dark (and somewhat fuzzy) compared to HDMI only. ANd this was not a Blu Ray disc, but an mp4 download. Decided to lower to 1 star - I really have to buy another one. You get what you pay for.
HDMI and RCA's do not talk to each other. You need a converter/adapter. I was trying to connect my ROKU 3, which only has an HDMI output, to my old Denon Amp, that only has RCA inputs. This little adapter works like a charm. I'd give it 5 Stars, but you have to provide your own power supply.
This little device does the trick for an older analog TV. I used it to connect a new Sony Bluray player to an old Samsung TV that still works just fine. Instead of spending several hundred dollars on a new TV, now we can watch Bluray disks, DVDs, surf the internet wirelessly and most importantly use apps like Netflix. Just make sure you set it for NTSC if you are in the US so the picture will display correctly.
This worked fantastic!! I walked into my local RadioShack in my town before i bought this item and I was just looking for something to make this connection. I was minding my own business. This young sassy girl that worked in the store comes to me as if she did not want anyone in the store. She asked me what I was looking for and I explained to her this HDMI to RCA problem to connect a new blue-ray DVD player.
It will get me by until I am able to afford a new TV. *** Just remember that you may or may not have to connect the Mini-USB cable for power purposes.
Answer: Thank you very much for your response.  I finally got through and according to Panasonic, the converter and an HDMI cable are sufficient to complete the connection.  Best wishes.  CarrieM
