  • Panasonic TX-42A400B Full HD 1080p Slim LED with Narrow Bezel - This is a slim and stylish TV with a very narrow frame around the screen that will look great in many different rooms and homes. As well as being slimline, LED TVs produce bright, eye-catching pictures and use less energy than traditional LCD or Plasma TVs.
  • Built in Freeview HD Turner for free-to-air viewing in High Definition
  • 100hz Back-Light Blinking switches the backlight off between frames to hide the lag whilst the TV panel responds
  • High Contrast - Dedicated processing in the TV improves the contrast, making the dark areas seem rich and deep and the bright areas stand out. Higher contrast makes detail easier to see and brings out the full depth of an HD TV.
  • USB Connection - A handy USB slot allows you to view your digital photos and movies on the big screen. It will even play your digital music from a USB stick.

There is a newer model of this item:

LED Display Technology: LED (light-emitting diode) TVs are actually a type of LCD TV. LCD HDTVs use standard compact fluorescent tubes to illuminate the picture. LED HDTVs, on the other hand, replace those fluorescent tubes with backlighting technology. LED TVs might therefore say "LCD display" on the packaging--this is perfectly normal.

Very nice TV. Good build quality, although the back panel is plastic, it feel strong, the stand has a metal frame although the TV isn't too heavy. Looks nice with the thin bezel. Picture quality is excellent, very clear, especially on the HD channels, Freeview HD built in is brilliant. Speak quality is good, doesn't distort but you can plug in additional speakers such as a soundbar if you want. The remote is quite small but the buttons are large with clear text. Easy to use menus. You can't swivel the TV on the stand like you can with some other models but this doesn't affect us. All in all, a very decent value for money TV from a good brand.

Excellent 42" screen! I use this to watch DVDs. There are two HDMI inputs (cable not supplied), and an RCA/Phono output (cable not supplied) for Hi-Fi/sound-system. The TV is both slim and light in weight. The stand is slim and relatively unobtrusive. The stand attaches by four screws on each side, and is easy to fit. The remote-control is small and easy to use (batteries supplied). The energy-consumption is A+ and is therefore very economical and environmentally-friendly. Excellent value-for-money. I am very pleased with my purchase, and award 5 Stars!
Up-date (5th March 2015): I have used a special cable (available from Amazon) to connect the TV sound to my Hi-Fi separate amplifier (which feeds to separate stereo-speaker cabinets). This cable is a stereo-plug attached to a RCA/Phono cable, which feeds from the TV head-phone socket. This connection allows me to listen to digital-music from my computer, and also to listen/watch music from YouTube. The TV powers the connection, so therefore, there is no-need for a separate digital-to-analogue converter-box and the associated specialist cables. This saves money, and reduces my electricity-consumption. In summation, I only use two HDMI cables, two RCA/Phono cables, and the Stereo-Plug/RCA cable. The system is accessed from the TV remote-control AV button, and by scrolling between HDMI1 (for DVD) and HDMI2 (for computer). I am very pleased with this TV/Hi-Fi system. I was requested by Amazon to supply the following answer to a customer-enquiry: The TV (including the stand) is 24-inches tall, and 38-inches wide. Award 5 Stars!

Very easy to set up and attach to Sky, DVD and Wii. The sound, picture and options are easy to use.
Very pleased

Arrived in good time and well packaged, its in our lounge and working and sounding excellent. Will be buying another for our dining room but in a 32 inch size, i would say to any one that Panasonic are always excellent products to use.

Love this TV. In particular, I find the sound quality excellent. We have had a flatscreen Toshiba for about 5 years now, and the sound quality on the Panasonic is so much better, we can hear the voices so much more clearly now, we were getting pretty reliant on subtitles and thinking we may have hearing problems!

Ordered Friday lunchtime and delivered saturday 12noon. the 42" is plenty big enough for my flat and love the way the screen goes right to the edge of the unit. This was an upgrade from my ten year old 30" HD ready Toshiba - the improvement is incredible, picks up all the freeview channels and HD channels on a very weak signal, Plenty of settings to play with which is just as well because out of the box the screen is bright and colourfull - once tamed it looks beautiful. Works best on my ps3 both games and blu-rays, Planet Earth is simply stunning. I did panic when it turned itself off after 4 hours, however soon realised that it has an auto-off function which can be disabled in the settings. I like the way your screen settings stay for each input so if you turn the colour up for games, you don't have to alter it every time you switch between av and tv.. all in all I am very happy with this product. The only potential downfall will be reliability- if it breaks within the first year i'll be back to update this !

**update: you can spend all day playing with the colour brightness contrast and sharpness OR simply turn down the back-light-blinking to 50 for a perfect picture.

If you don't need a smart TV then this is well worth considering. Excellent picture, nice thin bezel, easy to set up, sound isn't the best but not too bad. I didn't buy it for the sound anyway as it's hooked up to a dedicated surround sound system. For my viewing I used the factory dynamic setting and toned it down slightly in the settings, this gives a great picture well suitable for TV, films and games. For this price you can't go wrong, very pleased I went for this model.
