I'm having issues with RF interference (Universal Remote MX-880 & RFX-250 Receiver with Samsung plasma 50" HD TV and TiVO HD). The receiver and all equipment is in a closet in a small room just next to the den in which the TV is located. I thought maybe this "masking tape trick" I'd read about might work, but now I see that it addresses only IR interference??
It's quite maddening because I can go for days, weeks and sometimes months without any issues and then I'll have interference occur (the second light that shouldn't be on is either dimly lit or brightly lit). Repositioning rarely helps. This occurs sometimes for just an hour or so, sometimes for most of the day, sometimes just for that one day, sometimes over the course of 2-3 days or more.
This renders the remote either completely useless or else I have to click several times before the command will register--VERY aggravating!
I've noticed that sometimes some functions seem unaffected (mute, turning TV/receiver on/off) while others won't work at all (FF/REV, channel change, switching between live TV and Now Playing list). Also, sometimes the TiVO remote works (while I'm standing in the room with the equipment) and sometimes it won't. Of course, even when it works that's hardly a solution since I have to go to the equipment room and can't see the TV from the there.
The problem is so intermittent there appears to be no rhyme or reason and I've no idea what could be causing the interference. There is nothing different going on in our home during the times of interference. I can only surmise it has to do with a neighbor or environmental factors beyond my control?
This has been an intermittent problem ever since we first got the system about 6 years ago. Because the original Universal Remote died, I recently replaced it with a later model (MX-880) and experience the same trouble. The guy who put the system in hasn't been much help. Another guy I hired was some help, but the problem persists. Any help would be GREATLY appreciated!
