I have been programming an MX890. This is not the first URC remote that I have programmed. I also have been successful in programming my remote (MX880). But I am experiencing a problem with the MX890 that has me stumped.

I started off programming the unit using only IR and I was able to make it work perfectly. I then added the MX350 flash unit and now it will not power on my Samsung TV. I have tried everything I can think of but nothing seems to work. I also have separate button that allows me to access all of the functions of the TV. When I go to this page the power button works just fine.

I am using a macro to turn on my media system and as I indicated it worked perfectly when only using IR. I am stumped can anybody help?
