I recently updated my system to include a Panasonic TC-P46X3 and a 722K. My previous system, using a 508, a Sony CRT, and an Onkyo receiver worked flawlessly with a Harmony 880. After I went through a couple of them (the charging issue) I saw that Monster Cable offered the same guts under their own name. Though it's a different website, the programming is exactly the same and it operated the old system perfectly. After many, many remote updates I still have problems. The remote won't turn on the TV. I leave the 722K on all the time so it's not an issue. About the only functionality the remote now has is turning on the Onkyo and changing its volume. Not only do I not get a power on, but after I manually power up the TV the remote won't change channels, display a guide, etc. The menu choices on the screen are pretty cryptic also. My TV and remote were configured for remote 1 address. The original remotes still work all of the component functions. Has anyone run into this previously and have any tricks for getting everything working together?
