I am the Maintenance Director in a Long Term Care Facility and we are having a HUGE problem in our resident rooms. As you may have already guessed, either both remotes control both TV's... or one remote controls both TV's. Our cable supplier, Spectrum, recently 'upgraded' the network to carry HD. Which meant we had to now have all DTA's in our rooms with a 'universal remote.' In several rooms (upwards of 30 different rooms) we are having this issue. I have this issue in several rooms whether the TV brands are different or not. I do understand that in some cases TV codes overlap because of the RF issue within the programming. It's my understanding that the federal govt. maintains these codes and that only 'so many' (only 16?) codes have been released into the general public for civilian use. So, RCA might put code *1234 on every 5th TV made, and LG might put code *1234 on every 10th TV made. Is this correct? I'm having this issue in so many rooms that swapping TV's with new ones would be cost prohibitive (and could potentially still have the same effect) if the latter is true. Also, trying to figure out what remotes work with what brand is going to be mind-blowingly time consuming and tedious. Is there any other way to correct this issue? Adding in another piece of equipment and/or something aesthetically pleasing to the remote itself to quelch this problem? I've read where some people had used some sort of peel and stick label over the remote sensor to weaken the RF signal enough that it didn't effect the other TV in close proximity. However, the down side to doing that, is that you would have to be VERY direct with the TV you wanted to actually control, and make sure that it is pointed directly at the TV sensor etc. I fear doing this would only add to my numerous maintenance calls in the run of a day with "remotes that don't work." Any help at all would be greatly appreciated! Thank you all so much!
