Liam: I asked one of the full timers today, and his description of the Samsung way of switching tuners matched yours. I actually tried it out on an 55H7000 - you go to menu, then broadcast, then the aerial, then fiddle around there. A right pain. I didn't get a chance to look at the LG's, but my mate confirmed that the Panasonic's are easy ( same as about 5 years ago), and the Sony rep showed me their system, which seems very similar to the Panasonic. You flick down through the sources, and you can even choose to leave out the ones you dont use.
If your not bothered about having Freesat, then Sony or Panasonic (if you are) sounds easier. The alternative is to just get a seperate Freesat box ( less than fifty notes) and just flick between sources.
Bigger question - is that the right size and technology for the person? You'll be able to go up one size from the current TV, so a 40 to 48 switch works well, but for 4K I'd be thinking 2-2.5 times size of screen. If the person has fast broadband (20mbs plus), uses Netflix, and wants to stream movies/sport, then 4K makes sense. On the other hand, if not, then a decent mid range HD might do fine. To be fair, the prices for a 2015 40ish TV in the mid-range are around six to seven hundred, which in some cases is only about 50 to a hundred less than the 4K ones! If you really didn't care about sat. built in or 4K, then grab a UE40H6400 while you can - about to vanish but cracking value at 399.
Perhaps the Sony x83 with a Freesat box (if you didn't want to use to use the generic sat. tuner) - very good picture in 2K, 4k set, and easy to use. If not then the 7000 (we have the 40in, not the 43), but its a lot of cash to pay for a Freesat tuner that's a pain to switch to and from.
MikeB: Thanks for those updates. The real problem I'm trying to solve is multiple remotes. This lady has no problems when using my LG7700 but at her home she has a 32" Samsung plus a combi STB. The problem is she accidentally presses a channel button on the TV which then reverts to analogue and she has nothing. She rings me and tells me the TV is not working. So I have to go through a series of instructions to get her picture back. If there was only one remote, and switching between SAT and Saorview was simple we'd all be happy.I'll pop into Curry's and have a look at the Panasonic - maybe get a good FHD before they are all gone.Thanks again,Liam
Liam: A 42in Panasonic 740 from last year would be perfect, although goodness knows how your going to get one. Its basically a mid level panel with Freesat and some nicer styling. Great simple remote, Freesat, and pretty simple to go from one source to another. They vanished late last year, although the Panasonic area rep said they couldn't keep up with demand (which was strange since they were a lot more money for much the same panel!).
By the sound of it, the person using it would get on very well with a Panasonic remote, and its a decent bit of kit. Not 4K, but thats not the end of the world. However, its a 2014 model, so grab one ASAP.
