Not really.
Here's a suggestion though...if there's one tv on the right and one on the left, make a small cardboard "divider". bend a thin piece of cardboard into an L shape so that one side lays flat on the tv panel, and and the other points right at you. Put the divider on the right hand side of the IR receiver of the TV on the left, and vice/versa for the TV on the right.
In a worst case scenario, you may hove to practically build a small tube around the IR receiver on the TV so that you practically have to be in front of it to use the remote (the smaller the tube, the less sensative it will be to the other remote. the deeper it is affects this too)
Experiment with what works best for your specific layout.
There used to be a time where you could get ultraviolet emitter/detector pairs, and I'd tell you to go ultraviolet on one set, but at the moment, this is the best I can suggest.
Something that MAY work (although I have less faith in this) is to experiment with different shades of red gels (light filters) matching up the same shade of red to each remote and TV. IE - cut a tiny strip of the shade-1 and place it over the transmitting LED of one transmitter, and likewise on the corresponding TV. This may limit the amount of light that gets through from each remote to each TV enough that only the remote for it's corresponding TV works.

And finally, this one can take some experimenting but it works like the building of a tube.
IF there is a way (without breaking boards etc) to move the IR receiver deeper into the TV, you will eventually find that ideal depth where it only responds to a remote directly in front of it, or at least stops responding to the other remote.

I have in the past suggested the tube method on the remote but inevitably people kept breaking off whatever was attached to the remote...but if you can move the transmitter diode back into the casing (again without breaking anything) the remote will be much more directional and less likely to control anything that it's not being pointed right at.

Grundig how to

Never set remotes beside each other and leave the room. You never know what they might do when you not looking.

Actually, unfortunately if both remotes are using the same frequency for some options there is not a whole lot you can do to change the remotes themselves.

What you can do: block (lay something in front of) the stereos remote sensor location. Or turn the stereo it's self 90 degrees. This pretty much makes using the stereo's remote a pain, but you'll change the TV more often.

My ceiling fan/light goes on when I am not in the room. The remote is on the bureau. I sometimes put the remote in another room but the fan/light still goes on. Model 327185-060

The simple solution is to turn the wall switch OFF when, the fan is not in use. I really don't think the remote alone is the culprit. Because, you say it happens even when it's in the bureau or in another room. Remote controls for ceiling fans have a very short range and are generally infrared remotes, rather than radio frequency remotes. So, if the infrared signal does not reach the receiver's sensor in the fan, it won't function. If it's a radio frequency remote control, do you have any other remote controlled fans in the house? If so, does the suspect fan seem to turn ON after you have activated the other fan? If that happens, it means both remote controls are on the same frequency. Changing the frequency of one, should solve the problem. See your Owner's Manual for directions on how to reprogram the frequency codes.

If none of the above solves the problem, maybe you should contact the "Ghost Hunters" TV show.

Hope this helped you troubleshoot and solve the problem. Thanks for choosing FixYa.

I have 2 Vizio tvs with different remotes. But one remote will turn both tvs on and also change them. I don't want this to happen, can you help me?

There is nothing you can do about this. The remotes are using the same Infrared frequency, and this will cause both tv's to change at the same time when pressing buttons. You would have to walk right up to the reciever on the tv to change just one tv. This happens with any equipment that uses the same IR frequency

It is possible that there is other equipment which uses a similar frequency, this can be a cordless phone or a gate remote or other device capable of transmitting frequency

There should be dip switches in/on both the remote control and the ceiling fan that enable you to change the control frequency. The only thing that you have to ensure is that the two components are set to a matching frequency.

The switches in the remote are located in the battery compartment just above the batteries. Remove the dome on the ceiling fan and you should find the switches for that unit. Just compare the two and match whatever changes you make from one unit to the other.

TV remote is turing on VCR

Is it a original remote or a replacement universal remote? If it is the latter, then it looks like someone has accidently programmed it for the frequency which is compatible with the recieve frequency of the Remote sensor of your VCR or DVD player.
