Is the RC the original for direct tv box?, if not you have to find the code for the direct tv box, separate from the tv rc code.
if it is the original rc for direct tv, look for the code in the original papers from direct tv.

Good day,
I might be missing something here, but if YourTV has the basic controls on the TV itself, such as on/off volume, and channel select, then just turn on tv, and set it to channel 3.
Use your converter box remote to scan for channels, and other options it has as needed.

I can help you reprogram your RCA RCR311B for all your converter box.

Please review my Fixya Tip posts for:

I assume, that the TV is skipping chan 3 when using the Channel buttons on the TV.

You can try 2 things.. First see if your converter box will use chn 4. Usually there will be a very small switch on the back of the box marked with a small 3 on one side and 4 on the other. If so, use that till you get a replacement remote.

If that's not an option, you can also, Re-scan the channels on the TV. to find all available chn for memory.. BUT FIRST making sure that the converter box is on and working.
The TV shuold then detect that there is a signal on chn 3 and make it available to the chn buttons on the set.

You will have to use the menu buttons on the set to do this.. Hopefully one of the buttons is the menu call up, then you use vol or chn buttons to navigate it.
Hope this helps
