Ok, so I found this: 2004-2005 Philips Digital TV Discrete Codes USA.
[Link: pronto.philips.com]It's a pcf file. I downloaded it but I really don't know what to do with it. I suppose the code I'm looking for is right there but I don't know how to get it and then learn it with my Harmony.
Please help me I'm new at this and not understandig a lot.
