URC MX-900 Programming

[multiham]

Hi-

Back in 2007, I had a small home theater system professionally installed in my family room. As part of the install, I was introduced to the URC MX-900. This unit was programmed for me. I also had the MRF350 installed so that the remote would work no matter where I was in the house. Things worked great until recently when the tv only turned on and off if you had direct line of sight from the remote to the tv. Every other piece of equipment (DVD, Cable Box, Receiver) still worked perfectly. Noticed that the "flasher" that connects from the MRF350 to the tv was no longer flashing when a command was sent. I replaced the flasher with another URC flasher and the light was flashing again. However, I still can only turn on/off the tv with direct line of sight. Is there any URC experts out there that would be willing to review the code I have in my remote and make sure it still looks good? I would appreciate any help! I never learned the programming language as it has always worked! The TV I am trying to control is a Sony XBR LCD

Thanks!
