I assume that you've already tried the search function built into the remote?

You can also get some codes to try by going to www.hifi-remote.com/jp1/lookup/  and select Brand Search.  That resource provide more codes than the OneForAll instruction sheet. Use URC-7940 as a proxy for URC-7930.   Whenever you try a code, make sure you check more than one type of key.  For TVs, probably Vol+/- are the best on to check with, but power and CH+/- may respond also.  If you can get the TV to respond to any key, even if it is the wrong function, then it is possible with patience to find all the functions.
