Televisores Panasonic TH-42PX60E vs. Philips 42 PF7621D

Ya por mas que leo no se por cual tv decidirme
Si alguien fuera tan amable de responderme con cual se quedaba,
pensando en un uso general, television (tengo tanto señal analogica
como tdt donde vivo) y ver dvd's en cantidades, ademas de exprimir
por fin los juegos de la XBOX 360.

Estas son mis elegidas:

1ª PANASONIC TH-42PX60E, PLASMA
2ª PHILIPS 42PF7621D, LCD

ALGUN CONSEJO COMPAÑEROS
MUCHAS GRACIAS

P.D.: POR CIERTO, ME GUSTA COMPRAR EN TIENDAS FISICAS.
ALGUN CONSEJO TAMBIEN SOBRE ESTOS DOS MODELOS PARA
SABER DONDE PUEDO ENCONTRARLOS MAS BARATOS,
APARTE VIVO ENTRE HUELVA Y SEVILLA

MUCHAS GRACIAS *;D

Con estas consideraciones, yo también voto por la Pana.

Suerte con tu decisión ;)

Sin duda, el LCD.

De los 9 paneles de plasma que conozco de amigos y familiares, 6 tienen más de 3 años y de esos 6, 5 están con marcas permamentes que coinciden con las bandas negras y con la zona de los logos de las TV, y todos están en sus niveles máximos de contraste y apenas se ven cuando hay mucha luz. (el que está bien es simplemente x q apenas se usa, y son todos de primeras marcas)


El LCD te durará más, sin duda. (objetivamente demostrado, no x q lo diga yo) y no son aparatos de un coste tan reduido como para cambiarlos cada 4 años. (aunque eso el lo que lesgustaría a los fabricantes)

Yo voto por el LCD sin pensarlo.

En concreto ese lcd se ve de maravilla.
Personalmente no me gustan nada las imágenes que dan los plasma. No me gustan los reflejos en la pantalla, no me gustan esos colores tan pálidos. Si encima lo quieres aprovechar para consola y dvd en cantidad, no tengo nada mas que pensar. El lcd de maravilla.
Cada vez que veo plasmas me decepcionan. Es cuestión de gusto personal por supuesto, cada uno creo que buscamos lo que pensamos que se ajusta más a lo que queremos ver en una pantalla.
Cuando veo algún plasma "interesante", que generalmente a coincidido ser algún Pioneer de los últimos, resulta que me parecen buenos porque me recuerdan un poco a la imagen de un lcd.

Saludos

el lcd de philips es una autentica pasada lo vi en eci y es un lujo
ya nos contaras

LO PRIMERO GRACIAS A TODOS
LO SEGUNDO, QUE ME ENCANTA SABER QUE HAY OPINIONES A FAVOR
Y EN CONTRA DE AMBOS, CON LO CUAL PUEDE QUE ME HAGA INCLINAR
LA BALANZA POR EL PHILIPS, PERO LA VERDAD, ES QUE ESTOY MUY CONTENTO
CON TODO LO QUE HE LEIDO DEL PANASONIC, Y ADEMAS AHORA POR EJEMPLO
HAY UNA OFERTA EN ECI QUE LO DEJA EN 1975 EUROS, SOLO POR TRES DIAS,
Y AYER LLAME A UN ECI E HICE LA RESERVA, PERO TENGO QUE PRESENTARME ALLI
ANTES DEL JUEVES PARA HACERLA EFECTIVA, PERO CREO QUE ME HACEIS DUDAR
LOS PRO-LCD'S DE QUE MI COMPRA SEA CORRECTA.

ALGUIEN QUE TENGA EL PX60 ME DIRIA ALGO A SU FAVOR, PORQUE ES LO DE
SIEMPRE, QUE SI VA A TENER MARCAS PERMANENTES DE LOGOS DE TV POR QUEMARSE
LAZ ZONAS DE IMAGENES FIJAS.
TAN POCO HAN AVANZADO LOS PLASMAS PARA SEGUIR TENIENDO ESOS DEFECTOS??.
NO SE, ME PONEIS EN UN APRIETO.

LO PENSARÉ HASTA EL JUEVES.

ESPERO ALGUNA RESPUESTA MAS, MUCHISIMAS GRACIAS A TODOS.

Creo que es interesante hacer esta lectura respecto al "libro blanco" de Panasonic sobre sus plasmas

Panasonic have recently released the following white paper on plasma facts and
myths:
Plasma Facts and Myths
Panasonic Presents Advice From the Video Purist Perspective
Commissioned by: Panasonic
November 2004
Executive Summary

The 21st Century display technology called plasma TV looks, operates and performs
unlike any previous device. No other television today offers the form factor, screen
size and performance of plasma. The purpose of this report is to provide in-depth
information about plasma technology. You will learn how plasma operates, the truth
about plasma life span, the so-called uneven aging phenomenon, and maintenance.
Performance criteria will also be examined so you can determine if a plasma panel is
right for you.

How It Works
Plasma displays use three types of phosphors (red, green, and blue). Like a standard
cathode ray tube (CRT) TV the phosphors glow to create an image. The difference
lies in the way the phosphors glow. In a CRT, electrons strike the phosphors causing
them to glow. A plasma display contains a combination of inert gases. Electrodes
inside the glass panel charge the gas, resulting in the production of invisible ultra
violet (UV) light. When the UV light strikes the phosphors, they glow, producing a
brilliant picture.

Advantages of Plasma
Plasma TVs offer excellent colour saturation, very wide viewing angles in both
horizontal and vertical planes, and are equalled only by the bulky flat-faced directview
sets based on traditional CRT technology. Their rapid response times assure
crisp images even when fast motion is present, such as when viewing football or
other fast-moving sporting events. Plasma televisions provide image brightness at a
level far higher than large-screen projection displays, allowing for viewing in areas of
high ambient light without washing out picture detail. (There are no direct-view CRT
sets with comparable screen sizes to plasmas that are 42 inches or larger.)
Panasonic black levels are close to direct view CRT levels, permitting superb deep
blacks and outstanding viewing in dark environments. Panasonic contrast ratios are
rated as high as 4000:1. Current LCD flat panels cannot achieve the dark black
levels or contrast ratios of plasma in a home theatre environment. Panasonic makes
plasma panels in widescreen (16:9 aspect ratio) with enhanced-definition, commonly
known as 480p, (37” & 42” have 852 pixels measured horizontally (H) by 480 pixels
measured vertically (V)) and high definition resolutions (37”=1024H x 720V; 42”=
1024 H x 768 V; 50” and 65” 1366 H x 768 V).

Lifespan
There has been much misinformation about the longevity of today’s plasma TVs. Like
all other display devices, there are two parts to a television. The first is the internal
electronics. Modern circuit designs are extremely reliable and all televisions,
including plasma’s circuits, are designed to provide extremely long life. The second
part is the section of the television that produces light.
In plasma, it is the phosphors within the glass panel. Phosphors are used to produce
an image in standard picture tube (CRT) televisions as well, and in three-CRT rear
projectors.
Television manufacturers base the projected life of all TVs on “half brightness,”
meaning the time it takes for the display to create an image that’s only half as bright
as when the TV was new. The three-CRT rear projector is generally rated at 15,000
hours until half-brightness. Direct-view CRTs are generally rated to 30,000 hours.
Panasonic plasmas have a half brightness rating of 60,000 hours – four times the life
of CRT rear projection. This equates to more than twenty-three years at seven hours
a day viewing, around the average daily TV viewing time per U.S. household. With its
inherent high brightness, a Panasonic plasma will likely retain its image quality for
many years.

Myths Regarding Plasma Televisions
While a CRT direct-view television is an analogue device that uses a picture tube and
the plasma is a digital device, there are many similarities between the two
technologies. As noted, each display uses phosphors to create light. While a directview
picture tube operates in a vacuum, and the plasma screen uses inert gases,
both are completely sealed. There is no possibility of the gas leaking out (barring
physically breaking the panel), and there is never a need to “recharge” or “refill” the
plasma panel. Conversely, there is no possibility of moisture leaking in, it can never
“fog up” like a car windshield and, unlike an incandescent light bulb, a plasma panel
doesn’t suddenly “burn out.”

Power Consumption
All Panasonic plasmas are Energy Star® compliant insuring low power consumption
in standby mode (a mere 18 watts), when compared with non-Energy Star® models.
The maximum power consumption during use depends on screen size; the 37-inch
diagonal models, for example, are rated at 345 watts maximum. However, typical
power consumption is much lower and varies depending on picture content and
display settings such as brightness and contrast. With typical content and display
settings, Panasonic plasmas have virtually the same power consumption as similarsized
LCD TVs.

Burn In
Much has been written about the possibility of permanently marking a plasma screen
by viewing a static image on the screen for too long. This is often referred to as
“static image burn in,” which is a misnomer. The phosphors are never “burnt,” rather
they are unevenly aged. While the possibility of uneven ageing exists, it can also
occur with any other phosphor-based display such as a direct-view CRT television or
CRT rear projection TV. Panasonic has developed new phosphors that are resistant
to image burn-in and has added other features that minimise its occurrence. One
such feature imperceptibly moves the image around the screen to eliminate sharp
delineation between dark and light areas.
There are several simple steps to take to further prevent the possibility of image
burn-in, which should be performed during the break-in period.

Plasma Break-In
Like a fine new automobile, the performance of a plasma TV can be optimised by
allowing a break-in period. By properly following these simple break-in instructions,
you should be rewarded with long-term enjoyment of your plasma TV.
Plasma phosphors are most susceptible to image retention in the first hundred hours
of use. The panel becomes considerably less sensitive to burn-in after this period.
Very often, televisions, including plasma, are shipped from the factory with the
contrast control at a high setting to provide a bright picture under typical dealer
showroom lighting conditions. In your home, the room light levels are usually one half
or less than that in retail showrooms. The contrast control may need to be lowered in
your home for comfortable contrast levels that do not induce eyestrain.
When the plasma is initially installed, videophiles say it is best to do the following:
? Make sure the display is in a viewing mode (aspect ratio) that completely fills the
screen (there are often three or more settings from which to choose). The panel is
shipped in this condition, in what is called the“Just” mode.
? Turn down the picture control (contrast) to 50% or less.
? Briefly engage the 4:3 mode to confirm the side bars are set to mid-grey (there is
usually an adjustment in the Set Up menu that takes the sidebars from black to
grey) to minimise the chance of burn-in.
? Return the set to a “full screen” (Just, Zoom, Full) position during the first hundred
hours of use.
? During the first hundred hours of use it is best not to view the same channel for
extended periods. This should prevent channel logos and other fixed images
found on some channels from being retained.
? Avoid any static images (video games, computer images, DVD title screens, etc.)
during the hundred-hour break-in.
After the hundred-hour break-in period, during the next nine-hundred hours:
? Continue to retain the picture setting at 50% or less.
? Limit the use of 4:3 aspect ratio mode (traditional picture size that does not fill the
entire screen) to 15% of viewing time.
? Limit the use of static images (computer, video games, etc.) to less than 10% of
viewing time.
After one thousand viewing hours, panels are much less likely to experience image
burn-in.

What to do if you see a ghost image on the screen
In the rare event you begin to see a ghost image on the display, Panasonic has
incorporated a built-in “white-bar scroll” feature to assist you. When enabled, the
scroll will (in many cases) reduce or eliminate image retention. Consult Panasonic
customer service for any technical support issues (800-211-7262 or
http://www.panasonic.com/support/).

Panasonic Plasma Picture Quality
Panasonic has included several exclusive features to provide the best picture of any
plasma television available. Here are the performance features that best separate
Panasonic plasma from the competition, as well as other technologies.

Contrast Ratios and Digital Artefacts
Earlier generations of plasma displays lacked true blacks and dark area clarity,
causing washed-out low-level detail and requiring viewing only in rooms with
relatively high levels of ambient light. Panasonic has developed the exclusive Real
Black Drive system that allows the shut off of individual picture elements (pixels)
within the panel, to produce a true deep black. Panasonic’s Gamma Enhancement
System allows near-black image information to be reproduced accurately. In addition,
the Gamma Enhancement System increases the number of gradient steps,
eliminating unnatural “dithering” artefacts that may degrade image quality. Dithering
artefacts are often noticed in programs with gradual brightness transitions, such as
wide blue-sky scenes. A dithered sky breaks up into tile-like areas of varying
brightness levels, instead of a smooth, uniform, natural expanse. The combination of
these Panasonic breakthroughs increases rated contrast ratios, up to 4000:1, and
allows Panasonic plasmas to reproduce 1536 different shades from black to white.
Many competitors’ designs are limited to only 256 steps, resulting in disturbing
picture artifacts.

Colour
Panasonic plasmas reproduce more than 1 billion colours, providing a rich natural
palette for superb reproduction of movies, broadcasts and home videos. Many
competing plasmas can only reproduce less than 17 million colours.

Angle of View
Plasma provides a bright, vivid high-contrast image with uniformity in both the
horizontal and vertical viewing planes. Flat LCD panels lose contrast as viewing
angle approaches the extreme. Only flat-faced direct-view CRT televisions have
similar viewing angles, but without the slim form factor that plasma affords. Providing
a remarkable picture at virtually any angle assures that everyone in the viewing room
— regardless if they are sitting, standing or even lying on the floor — will see the
same crisp clear images.

Rise/Decay Times
Plasma displays react very quickly to picture changes insuring exceptional viewing of
fast motion found in sports programs. Flat LCD panels often have slower response
times causing blurring with action and sports material.

Conclusions
As a relatively new technology, plasma faces challenges in the form of
misinformation; possible misuse by the consumer; and myths previously assigned to
preceding technologies that are carried over to the new. Hopefully this report has met
these challenges by reviewing plasma not in terms of strengths or weaknesses, but
in terms of actual capabilities and well-researched practices to achieve the best
consumer experience possible.
Plasma is a superior technology in its obvious display capabilities but also in its
longevity potential. With your attention to a few important settings and practices,
plasma will provide you with an exciting and reliable viewing experience for years to
come.

MAS O MENOS ME HA QUEDADO CLARO EL TEMA DE AL PRINCIPIO DE TENERLO
ES NECESARIO LIMITAR LOS CONTROLES DE BRILLO, CONTRASTE, FORMATO, ....
PARA EVITAR ESTE TIPO DE PROBLEMAS DEL FAMOSO QUEMADO, ES COMO EXPLICA
EL RODAJE DE UN COCHE, NECESITA UNA HORAS (CALCULO QUE CIENTOS) PARA
TODO ESTO, ALGO ILOGICO Y MAS DE UN PRO-LCD SE HARTARA DE REIR, PERO
ALGO DEBE DE TENER ESTA TECNOLOGIA PARA GUSTAR A TANTA GENTE.

ALGUN EXPERTO EN INGLES Y PLASMA QUE ACLARE ESTE DOCUMENTO A
TODO EL MUNDO QUE TAMPOCO SEA SU FUERTE EL INGLES

GRACIAS

Si ya tambien estoy interesado que algun experto haga una especie de tutorial universal para el rodaje de un plasma.
ALgo asi como las primeras x horas de vida el contraste que no esceda del x porciento dle total, el brillo este tanto por ciento, no conectarle fuentes que emitan x cosas.
Si como un pequeño manual de como no hacer sufrir el plasma y poder dormir tranquilos por la noche.

Yo sin dudarlo te aconsejaría la tecnología lcd.
Un amigo se dedica al servicio técnico de reparación de estos aparatos y me ha recomendado lcd por encima de plasma. Por lo visto las averías en plasmas supueran en gran modo a las del lcd. Me ha recomendado un lcd y a ser posible hasta 37 pulgadas.
Yo te hablo de estadísticas, no se cual tecnología sea mejor, pero en cuestión de fiabilidad está claro el tema.
Yo he visto plasmas y lcd y me decanto por los segundos. Además tienes que tener en cuenta que cuanto más grande sea la pantalla más se notarán los defectos visuales.
De todas formas en cuestión de plasmas mucha gente coincide en Panasonic como marca puntera.
Un saludo al foro.

Mas informacion, aunque sea en ingles
Esta vez es un "white paper" de Pioneer.
Muy interesante.

saludos para todos

Hola,
Yo me he decantado por el panasonic.
Me llego ayer, lo instale y puse matrix, se me caia la baba. La tele parece que va muy bien, aunque en honor a la verdad tambien se me hubiera caido la baba con la philips, ya que lo que tenia antes era una bluesky de 21". :-X
Cualquiera de las dos te ira muy bien, fijate en las conectividades y en la facilidad de manejo y el precio final que es lo que al final te puede marcar la diferencia. Yo las vi las dos en la tienda y no era capaz de sacarle diferencias visuales.
Saludos y que disfrutes tu tele.

Yo recomiendo plasma, los Panasonic no tienen problemas de retenciones en un uso normal.

Sólo recomendaría LCD si fuera a usarse mayoritariamente con consolas de juegos, pero para ver DVD, TV, la Panasonic PX tiene una calidad excelente (el mejor panel del mercado), y más con TDT.

No sabia que habia que hacerle un 'rodaje' a la tele. En el manual de instrucciones de la PX60E no pone nada al respecto. Lo que si pone es que la garantia excluye especificamente los deterioros por quemado. Mucho decir que han acabado con el problema pero se lavan las manos, cuando el rio suena agua lleva.
La tele viene con 4 configuraciones de contraste/color/brillo/etc predeterminadas. Aparte las puedes poner a tu gusto tb. Lo extranio es que de fabrica la configuracion que trae es la de contraste mas alto, que es segun lo que leo la pero para el rodaje.
Pero en fin, que yo estoy contento con la tele y ayer viendo master and commander me daba la impresion de ir subido en la fragata de russell crowe.
Y tb puse la videoconsola, una dreamcast (es que me resisto a jubilar esta joya :'(), y se veia de miedo.
saludos

LA VERDAD, YA HE HECHO LA RESERVA PARA LA PANASONIC, Y YA OS CONTARE PORQUE CREO QUE LLEGA PARA FINALES DE MES, AGRADEZCO A TODO EL MUNDO SUS OPINIONES, QUE SON TODAS MUY DIGNAS DE LEER, ESPERO NO HABERME CONFUNDIDO CON EL PLASMA, YA OS TENDRE AL DIA A TODOS.

MUCHAS GRACIAS
