Panasonic Viera TX-42AS740 LED HD 1080p 3D Smart TV, 42", Freeview HD, Freesat HD with freetime

Product information

The Panasonic AS740B transforms the way you watch TV with integrated freetime, catch up TV, 3D and Smart apps. Control everything through the easy-to-use Home Screen, or just sit back and tell the TV what to do using the built-in Voice Assistant. You can even stream TV and recordings to wherever you are with the TV Anywhere function.

Smooth Full HD 3D
More than just Full HD, the Panasonic AS740B comes with 1200Hz backlight blinking that creates fuller, smoother motion. The 1080p panel is also tuned for dramatic contrast so every detail shines

Freetime TV
With freetime you can take advantage of roll back TV for the past week, as well as enjoy access to a programme guide that displays catch up services like BBC iPlayer, ITV Player, 4oD and Demand 5.

TV Anywhere
Transfer TV or recorded programmes to your smartphone or tablet wherever you are. Thanks to advanced cloud servers you can watch your content just about anywhere with a fast enough internet connection.

Camera & voice control
The Panasonic Voice Assistant helps you to find your content without fiddling with menus and folders. Voiceprint recognition will even log you straight into your account complete with your own home screen and custom settings. Skyping friends and family is simple too thanks to the built-in Full HD camera with face recognition.

Apps, games & sharing
Connect to friends on Facebook, share your thoughts on Twitter or just browse the internet from your armchair. This TV connects via Wi-Fi or Ethernet so you can enjoy more services in one place. With catch up TV, fitting the best programmes into your busy schedule is simple.

My Home Screen
The Home Screen is your personal gateway to everything this TV has to offer. Customise it with shortcuts to your favourite apps and content or send it messages from your smartphone when you’re out and about (ideal for staying in touch with the family).

Sound Bars

With TVs getting slimmer and built-in speakers getting smaller - choosing the right sound system is more important than ever. Sound bars add that extra audio punch to all your movies, games and TV programmes. More affordable and easier to set up than a full size speaker system, they don’t compromise on quality either.

Q & As

Panasonic Viera TX-42AS740 LED HD 1080p 3D Smart TV, 42&quot;, Freeview HD, Freesat HD with freetime 4.4 5 5 5
Picture Problem Purchased this to replace my 3.5 years old Panasonic TX-L37G10B that is still a really good Tv and the picture is superb. Only reason for change is to have a "Smart" Tv. Disapointed with picture on "SD". HD picture is very good.I tried all settings and still the picture is not 100% clear. It is like 3D without using the glasses although only very slight blur. It gave me a headache watching it. I contacted Panasonic support who were very helpful and tried altering settings with them to no avail. In the end they did admit that they knew of the problem and said it was because there was so much going on behind the scenes with the Tv and that really the Tv was made for "HD" viewing. Well at the moment most programs are in "SD" so no good to me. John Lewis again very good and are collecting the Tv as I cannot deal with the picture. Looked on the internet since and have found other people having same problem. 05 October 2014
Great TV Bought it to replace our four and half years old Panasonic and we are delighted with it. 01 October 2014
Great picture The picture quality is fantastic, you fell you can step into it, even the 2D mode. 3D mode is good too, giving a real depth to the view. The TV looks good, it is unobtrusive in our lounge and fits in well. The Netflix app, and on demand apps are good, though the non BBC players are not found intuitively, you have press one of the coloured buttons on the guide. 10 September 2014
brilliant tv bought this from JL Peterborough , to replace my ageing panasonic plasma, all I can say is its awesome, voice control realy works.! picture is bright a vibrant. no need for a sound bar, as it goes quite loud, took a while to get used to all the toys , but it's worth it in the end , I love the pop up camera, pops up, then pops down when finished :) no motion blur at all.. highly recommended TV. 14 August 2014
Fantastic Picture This is an affordable TV with the most amazing picture quality, no motion blur whatsoever on freeview or freesat. Once connected to Wi-Fi it will play music and show pictures from my PC. Sound quality is not an issue as I use a Panasonic home cinema system. 11 June 2014
