First, have you checked the files section here to see if other users have TV's by these mfg's???

Second, if you have the original remotes just learn the codes directly using the neo.

If that does not help I know that there are alot of brands that are made by other mfg's and just slap a different symbol on the units. If you can find out who made the sets you should be able to use their codes (I think RCA makes sets for other brands)
