Need a code for a rcr6473D rca universalfor a aquos sharp tv

The Roku is an external media player designed to function with all TVs. Depending on the model of Roku you have you need to conext the video out whether it be RCA (the yellow red whit cables) or HDMI into the corresponding input on your sharp TV then with your remote or the input button located on the side of the TV you need to change the TVs input to the the same input you plugged your Roku into.

Any of these will work.

Your TV is a High-Def TV (HDTV) therefore you need a Rogers cable box and service capable of High-Definition in order to get the HD resolution you paid for with the HDTV. HD video requires HDMI or component video cable connections. Standard RCA AV (yellow, white, red) will not show HD video.

Having said that, you may want to hookup a game or VCR to the TV and therefore you will need to get a cable known as an AV miniplug. It has RCA (3) on one end for the VCR for example and on the other end is a Mini-plug to connect to the HDTV (Sharp). This cable is like the ones used on camcorders such as Sony. Make sure you get a cable with the right ends as depicted in your manual on page 14.

You'll have to Google online for a supplier. Sparco.com had these cables but are out of stock currently.

Find the user guide for your universal remote and use the RCA cable tv/satellite codes, and one should work for your RCA DTA800B1 converter box. My Sharp Aquos remote liked the RCA satellite code.

Check the cable box for the manufacturers name and see if that isn't listed in your owners manual.

This happens when you are connecting with a coaxial cable. If possible you will need to connect your set top box to the television with a composite/RCA cable and watch tv on input 2 instead of on input tv.

I have a similar problem. The Sharp TV aquos appears to be shutting down my blue ray player and dvd recorder when connected via HDMI. They work fine and never close down when I connect them via the rca cables either single video connection or a composite 3 cable rca lead. I have 3 HDMI inputs on the tv and the problem occurs on all 3. Any suggestions?

you might try unplugging the TV and then plugging in again. It worked for me

There is a code out there to try.  The code would be 47.  Just follow the steps in your manual on how to program this box and you should be able to go from there. Can't garantee that it will work as that code came out with the newer tv but it should work.

Digital inputs on Aquos TV's are "always on," usually the HDMI inputs and DVI inputs. As opposed to analog inputs 1, 2, or 3, are only activated once something is plugged in.
Try plugging in another HDMI sources into input4 or 5, if its still not working, the TV needs a new Main Board. Try calling Sharp 1-800-237-4277 and locating a local service center in your area.
