Just purchased an LG 7420P home theatre system. Very pleased with sound quality and the picture quality through my 51" Samsung plasma TV is stunning.
The only issue I am having is that the remotes for the LG and the Samsung have several buttons that inadvertently operate each of the two pieces of equipment (the LG receiver and the Samsung TV) This is annoying as I can be scrolling through menu options on the LG handset (adjusting settings or selecting an input etc) and the TV will suddenly go into standby. Similarly I might want to turn the TV into standby mode but leave the LG system on playing a CD or on FM - when I press the standby on the TV remote, the LG also goes into standby! I can easily turn the LG back on and thankfully this doesn't trigger the telly to come back on, so its not a major problem but just annoying! I've never come across the 'cross interference' of remote signals before, certainly not between two different manufacturers. I can't see anyway of reprogramming either the LG or Samsung remotes to work on different frequencies. Any ideas?

On my LG TV there is a setting called "ID" which according to the manual is the bit that changes the remote control settings if there is a clash with other kit. Not sure if there is a similar setting on the LG Home Cinema system. But it does show that the setting may not be called anything immediately obvious.

It used to be that to change the remote settings there was a little switch, under the batteries usually, to select the channel it uses. Haven't seen a remote like that for some time though.

Only to contact BOTH manufacturers, remote controls 'should' contain two different types of 'codes', one is the 'device code' (so tells it if it's a TV, VCR, DVD etc.) and another for the actual 'key' (so Volume+, Programme 1 etc.)

Even assuming your two items use the same remote control system (and I'm not sure what systems LG and Samsung might use) the TV should use a TV device code, and the theatre system a non-TV device code.

It is vaguely possible, that they use different remote control system, and that the combination of bits transmitted unfortunately happens to clash with the other make.

I would like to thing that LG/Samsung are aware of this, and 'may' have an answer - although it may be that you have to replace one of the items.

I think some TV's AV receivers etc had the ability to switch to a second frequency if you were suffering from interference. Quite a few years ago I had a VCR that had an A/B button to switch to an alternative frequency.

I may have sussed out the issue of my 'conflicting ' remote controls. The LG system has a function known as SIMPLINK. This is a facility for one pice of kit to control various functions of another piece of kit via the HDMI connection. I think it's possible that the Samsung TV is picking up on these signals. This is all new to me so I will be looking into this to see if this facility can be disabled.

If both units incorporate CEC over HDMI, then it will indeed allow you to use a single remote for both items,

Not exactly - same frequency, but a different device code.

Thanks for your input Nigel - the issue I was having was down to me not fully understanding what SIMPLINK is. LG equipment uses the SIMPLINK system to enable various bits of LG gear to work together and to be controlled by one remote control via signals sent through the HDMI cable. What I hadn't realised was that Samsung have their own system called Anynet. The SIMPLINK and Anynet systems are fully compatible with each other, and for some people, being able to switch on and off all their connected gear with one button press on one remote, could be useful. However, for me it is unnecessary and I have now switched off the SIMPLINK on the LG and now my TV remote and LG remote work independently of each other - which is all I ever wanted!

They are just the manufacturers different names for CEC (developed by Sony/Panasonic), the point of it is that it works across different makes - which is pretty sensible when you think about it.
