We've got a three way HDMI switch to enable us to connect a Fire Stick to the tv. On it there is a) the on/off indicator light and then three other lights which indicate whichever HDMI(1, 2 or 3) "channel" we are using. We have ab IR remote to select 1, 2 or 3.

The problem is that this seems to be affected by the tv remote and we sometimes find that the HDMI selection changes when it shouldn't do and we have to reselt whichever one we want.

Anyone know anything about these things please?

Urgent Bump please

Why don't you ask people who know these things, instead of a load of people who think they know these things ...

The problem is probably that the HDMI switch is either using a similar IR protocol to the TV, or is using a very basic protocol (e.g. a simple 'advance only', round-robin (1-2-3-1-2-3...) controller that takes any old IR pulse).

If it's a protocol problem, I'd try each of the TV remote buttons in turn (turn the TV off), and see which of them is causing the problem. At least you'll know not to touch them...

Does the HDMI remote cause any change to the TV? If not, it's probably a pretty dumb protocol being used by the switch.

There's not too much you can do about it, barring physical separation. You might be able to reduce the sensitivity of the HDMI switch by adding an extra piece of IR filter material over its IR control window.

Like most forums, there will be people who think they know what they're talkiing about, and people who do know what they're talking about. Just like here.
