Ok, Update, I'm at another client's house who has a TSU9200 & RFX9200.

Their TSU9200 has been saying command failed for every button pressed.

I just opened their cabinet to their stereo system and I cycled the power of the RFX9200 and then I pointed the TSU9200 directly at the RFX9200 from a distance of like 6" and the command worked!!!!!

And now all commands work once again.

I closed the cabinet doors and walked away and tried the TSU9200 again ans it worked!!!

So, I guess for some reason the link between the TSU9200 and the RFX9200 gets lost and that's why the "Command Failed" comes up.

And once you do as I did above the remote should work again.

I instructed my client to do this for the time being until we get a fix from Philips.
