Test: 37 "LED TV Panasonic TX-L37D25E for 1.100 euros

You can not see the subtly gray-mottled TX-L37D25E at first sight, what everything in it is. Its housing is nicely flat, but not boastfully thin, the indentation of the frame is an interesting design aspect. It is very pleasant to touch the plastic. Fingers do not leave any marks as on the exaggerated high-gloss black competitors. The foot does not seem to attract dust so strongly.Panasonic here combines the practical with the beautiful, which also becomes clear in a compromise at the construction depth. The D25 and D28 series are Panasonics’ first models that use LED lights to illuminate the LCD panel. As you can see with other LED TVs, these devices are even more compact, but Panasonic did not want to compromise the picture and sound quality.


More depth in the lower housing part gives the speakers air for breathing, the centimeter more behind the LCD display allows for stronger diffusion layers so that the light of the LEDs can be better distributed over the entire surface. The best lighting we've ever seen on an edge LED TV has emerged.


Also the sound is acceptable. The DSP chips do not have to screw too much on the frequency response and twist the phases.


Whoever calls the equipment of the Panasonic comprehensive, still understated: the TV has really every technical detail that has ever been demanded by customers and test editors, and these innumerable modern features have also been very well thought out.



This starts with a quad-tuner that receives HD signals from the air, cable or from space, and which is supported by a CI-Plus interface, which makes it HDPlus-compatible. If you look at recording restrictions that some HDTV stations give their films with, Panasonics USB recording function is brilliantly solved.


A hard disk (no stick) is filled with programs that you want to spontaneously record or programmed by the comfortable program guide. This also works unintentionally in standby, and during the recording you can watch an "old" record or enjoy an AV channel Blu-ray.


Only a fast timeshift activation is missing. For this, a background recording is possible, so that the currently viewed program can even be rewound directly.


Also the many multimedia functions of the Panasonic TV can inspire. As a source serve USB stick or SD card, DLNA server or the Internet. The connection is recorded either via LAN or an optionally available WLAN USB Dongle.


Which videos, photos or music files are supported depends on the sources. The most important formats, including AVCHD videos and AAC music, are played. The media containers TS and MKV are still ignored and portrait photos are rotated automatically only via SD or USB.


Excellent is the speed at which the TV navigates through the folders and plays content. A DLNA renderer function is missing, so the TV can not be controlled from the outside (via Windows 7, for example) to access media content.


The Internet portal Viera Cast started last year with Picasa and You Tube and has meanwhile with interesting contents added. These include Tagesschau, Bild.de, Eurosport, Q-Tom and Dailymotion, and all offer video content. Again, search functions and page views are processed quickly. Soon a Skype function including video telephony is to be introduced.


The test showed what a mature HDMICEC control can do. Panasonic was the pioneer of this communication technology and calls its own variant "Viera Link". For example, Bluray players, recorders, amplifiers and TVs are switched on, off and on demand. And when a BDFilm runs, the TV remote control automatically takes over all menu and drive functions.
