Try 571. If this doesn't work try setting the code via the automatic programming feature.

RM-810 Automatic Searching
1. Turn on the TV
2. Press the “TV” key (*, **, or **) you want to program on the remote. The light should flash once.
3. Press the “Set” and the “Power” button simultaneously for 2 seconds. The indicator light should stay on.
4. Release both buttons. The indicator light will flash constantly indicating the automatic search mode.
5. After the indicator light illuminates, release the two keys simultaneously.
6. If the controller can turn off the device during its auto programming, you can finish programming in 1.5 seconds by pressing any other button on the controller
7. Check whether operation of other buttons is at normal state. If so yor setting is successfully accomplished.
If you cannot control the functions, try steps 2 through 5 again. If you do not press any button, the auto search function will stop after 30 seconds and the indicator light will go out and you will have to restart the auto search.
Let me know if this works for you. Thanks.

0027

If your RCA converter remote functions as a universal remote one of those codes should work. If not, you should be able to find a basic universal remote for around $10 at any drug store or grocery store. If you have a more complex home theater system and are interested in advanced functionality, Logitech makes an excellent line of universal remotes that range from around $80 to hundreds of dollars.
