have you been searching ONLY using this model number? manufacturers tend to use the same codesets for a number of their models, have you tried ANY codes posted on this site? what remote do you have? ALL the discetes for Panasonic are on this site, do a search then test a few, the only document we have from Panasonic is posted in numerous places on this site, i'll save you some time:
[Link: panasonic.com]the latest panels seem to be less and less responsive to these codes however.
