I just picked up an old MX-500. I found out that this remote does not do discrete codes. The only way to get it to learn discrete code is to get another remote (Radio Shack or One For All) that does discrete codes and then learn these keys to the MX-500.

My question is, which inexpensive remotes can I use to learn these discrete codes to my MX-500. Lot of people have mentioned the older models from Radio Shack such as 15-1991 and and 15-1194 or the Cinema 6 or 7 All in One. These models are very old and they are hard to find. Does anybody know of any other current models that are inexpensive that does discrete codes. I live in Canada. I bought a One For All 5 (Model #COARC05G) learning remote from the Source, however it does not look like it does discrete codes.

Can someone recommend current models of inexpensive remotes that can do the discrete code, that I can buy in Canada.

I also need the discrete codes for my Samsung LCD TV and my Samsung Home Theater System. Would somebody have these codes that I can use on this remote. I have the following models:

Samsung LN52A850 - LCD TV
Samsung HT-TZ515 - Home Theater System

Thanks.

There are Discrete code for the TV that you have, unfortunately the HTIB (Home Theater in a Box) does not have a discrete codeset.  That is one of the limitations of the HTIB.  I would just use the remote that came with the HTIB to control both,  the HTIB is what is limiting you here.

Can u please guide me or tell me the discrete codes for this tv.

For generating discrete codes,  a good choide is the RCA RCRP05B, which I believe is available in Canada.  Slightly less good, but still good would be to buy on eBay an Atlas 1056B01.  It's used by many cable companies.  Make sure to not get the newer 1056B03, because it can't be manually programmed.

Use setup code TV 0060.  On is EFC 00001, and Off is 00253.  Either of the above remotes have TV 0060.  The Comcast Red OK/Select button remote will also work.

Thanks for your help. What about the code for selecting the input Component Video 1, Video2, HDMI etc.

Do I need to buy the JP1 cable to program the RCA RCRP05B for the discrete code or can I just program it manually.
