remote control issue

[ultinator]

Hi,

in my house I have a wall mounted LG tv, underneath an LG sound bar, and under that an electric fireplace (used for the fire effects and backlights, NOT HEATING)

All 3 have their own remote, but the LG tv has a 'magic remote' that controls the sound bar too.

There has never been any cross controlling between the LG products and the fireplace

Had my niece over and she chewed/dribbled over the remotes.

now the 'magic remote' and sound bar remote can intermittently turn the fireplace on and off.

This is an issue as my brother put a 3a fuse in the spur, so that if anyone tried to turn the fire heater on, the fuse would trip rather than melt the set-up above.

This has happened a couple of times now, and replacing the fuses is tiresome if its to keep happening. I will remove the connection for the heating element when i get a chance.

My question is, why would the only variable (baby drool) affect the remotes? I would have thought they are on a fixed frequency and a small bit of ingress wouldnt be able to change that? so why do the tv/sound bar remotes switch the fire on now?

Is it possible that it could always happen, but the remotes were oever aimed at the fire, but now the drool or chewing, has scattered the IR over a wider area?

Cover the IR sensor on the fire with a flap of tape so you have to fire it accurately from a close distance.

Some remotes can be set to respond to other signals and be programmed to run different TVs etc. perhaps this is what has happened by chance.
