Basically, you're asking for a Code Search for these devices, so please use this template to avoid many others asking you individual questions:
1. Device:
2. Type of device:
3. Year:
4. JP1/UEI Remote model:
5. Do you have a JP1 cable?
6. Still have original remote?
7. Checked the file section?
8. Checked Pronto file section (at R/C)?
9. Partially working setup code?
10. Learning remote question?
11. Have you tried the JP1 Lookup Tool?
You see, if you have a cable then are likely upgrades for most of your devices in the File Section of this forum. If there aren't then you can learn the codes from your original remote (if you have it). That would get you most of the way there and all you might need help with is finding the discretes. For the Samsung you could look at the many upgrades and see if any have discretes that might work for your TV - just becasue they aren't for your particular model doesn't mean that they won't work. There is also
this file which lists many Samsung discretes.
