Question about Sony Grand WEGA KDP-65WS550 65" Rear Projection HDTV

7 Answers

Burn In I've heard of burn in problems with LCD and Plasma's especially when viewing a Standard Definition program on a widescreen and seeing the "block" retained within the screen. Seems to be happening here (the box area of the 4:3 is darker than the outer sides of the 16:9 wide. Very apparant when watching lighter scenes full screen. How can this be rectified so that the full screen is as close to being even if there is in fact burn in?

If you have the right equipment like an XP computer and a video out, try cycling Red, Green, Blue White, Black for the day on the my pictures screensaver with 1024x768 BMP's of each color, this will even out your TV, It works like a charm for burnt LCD pixels and Standard TV's too.

Thats bjust what I recomenedfor another burn in problem as I sugested using a test disc using differant colors or white but white would certainly be the best and yes the old camera tubes used to get a burn in them and showing a white well lite screen to them helped save alot of tubes!!

There's an old, old trick we used to use on the old three gun pro studio cameras with screen burn. We focused the camera on a white sheet of cardboard which was brightly lit and just left the camera switched on for the day aimed at the card. It worked a treat. I wonder if you had a similar setup with a videocam and played it back through the monitor on full screen, with the monitors brightness turned up full it may clear the darker area. I've never heard of it being done with modern equipment but hey, it's worth a try. It would certainly do things a lot faster than just noise on the screen. BMW

If its not genuine permanent burn in, there's some chance you could get rid of it by playing a no signal channel - the kind that gives you the snowy picture. leave it like that for a day and see if theres any change. Good luck

Is plasma burn in real?


Hello.
Well it does not catch any real fire if this is what you mean. What actually happens - PDP (Plasma Display Panel) is "burning out" throughout it's use. Especially if someone is watching TV channels with fixed logo (Like CNN for example). That steady image can get "burned in" into the screen and stay there forever. So it is important to watch different channels and programming so screen does not get any permanent "marks" and spots.
LCD and LED technology does not have this issue because of totally different method of producing image on the screen.
Regards.
Russ.

Whats the difference between a LCD and plasma


Answer: Outward appearances are definitely deceiving when it comes to LCD and Plasma televisions. Although both types of televisions are flat and thin, they employ different technology in an attempt to deliver similar results. Plasma TV Overview Plasma television technology is based loosely on the fluorescent light bulb. The display itself consists of cells. Within each cell two glass panels are separated by a narrow gap in which neon-xenon gas is injected and sealed in plasma form during the manufacturing process. The gas is electrically charged at specific intervals when the Plasma set is in use. The charged gas then strikes red, green, and blue phosphors, thus creating a television image. Each group of red, green, and blue phosphors is called a pixel (picture element). Although Plasma television technology eliminate the need for the bulky picture tube and electron beam scanning of traditional televisions, because it still employs the burning of phosphors to generate an image, Plasma televisions still suffer from some of the drawbacks of traditional televisions, such as heat generation and screen-burn of static images. LCD TV Overview LCD televisions, on the other hand, use a different technology (see also question #1 for this same explanation). Basically, LCD panels are made of two layers of transparent material, which are polarized, and are "glued" together. One of the layers is coated with a special polymer that holds the individual liquid crystals. Current is then passed through individual crystals, which allow the crystals to pass or block light to create images. LCD crystals do not produce their own light, so an external light source, such as florescent bulb is needed for the image created by the LCD to become visible to the viewer. Unlike standard CRT and Plasma televisions, since there are no phosphors that light up, less power is needed for operation and the light source in an LCD television generates less heat than a Plasma or traditional television. Also, because of the nature of LCD technology, there is no radiation emitted from the screen itself. Plasma vs LCD The ADVANTAGES of Plasma over LCD are: 1. Larger screen size availability. 2. Better contrast ratio and ability to render deeper blacks. 3. Better color accuracy and saturation. 4. Better motion tracking (little or no motion lag in fast moving images). The DISADVANTAGES of Plasma vs LCD include: 1. Plasma TVs are more susceptible to burn-in of static images. 2. Plasma TVs generate more heat than LCDs, due to the need to light of phosphors to create the images. 3. Does not perform as well at higher altitudes. 4. Potentially shorter display life span - this used to be the case. Early Plasmas had 30,000 hours or 8 hrs of viewing a day for 9 years, which was less than LCD. However, screen life span has now improved and 60,000 hour life span rating are now common, with some sets rated as high as 100,000 hours, due to technology improvements. LCD television ADVANTAGES over Plasma include: 1. No burn-in of static images. 2. Cooler running temperature. 3. No high altitude use issues. 4. Increased image brightness over Plasma. 5. Lighter weight (when comparing same screen sizes) than Plasma counterparts. 6. Longer display life used to be a factor, but now LCD and Plasma sets both have at least 60,000 hour or higher lifespans. DISADVANTAGES of LCD vs Plasma televisions include: 1. Lower contrast ratio, not as good rendering deep blacks. 2. Not as good at tracking motion (fast moving objects may exhibit lag artifacts) - However, this is improving with the recent implementation of 120Hz screen refresh rates and 240Hz processing in higher-end LCD sets. 3. Not as common in large screen sizes above 42-inches as Plasma. However, the number is growing fast, with 46 and 47-inch screen sizes becoming more common, and some LCD sets having a screen size as large as 65-inches also available to the general public. 4. Although LCD televisions do not suffer from burn-in susceptibility, it is possible that individual pixels on an LCD televisions can burn out, causing small, visible, black or white dots to appear on the screen. Individual pixels cannot be repaired, the whole screen would need to be replaced at that point, if the individual pixel burnout becomes annoying to you. 5. LCD televisions are typically more expensive than equivalent-sized Plasma televisions (although this is changing), especially when comparing EDTV Plasmas to HDTV-LCD Televisions.

I'm confused about HD (high definition) and digital


In Australia analogue TV signals will be phased out and finished by the end of 2009 (I think).
If you have a standard analogue TV you won't be able to receive any more free to air analogue TV programs when they stop brocasting these TV signals. To recieve the new digital signals you need to buy a digital set top box (which receives digital TV signals and converts it to analogue signal that can be displayed on your old TV). The set top box will only receive Standard Definition signals and this is a lower screen resolution that is available from High Definition signals.

Digital TV signals offer approx. 15 TV channels ln High definition and Standard Definition, different programs channels will be available from the same TV broadcaster, although the High Definition pograms will also be repeated on one of the Standard Definition channels.

High Definition gives a sharper image than Standard dedinition, but you may not notice much difference because it depends much on the material you are viewing, You will notice how clear DVD and BlueRay movies are compared with the VCR tapes. To get the best images from DVD movies your player must be connected to the HDMI connector on your High Definition TV (provided your DVD player has one, usually BlueRay players will have one, they also will play normal DVD disks).

If you purchase a new High Definition TV you will also be able to receive all the Digital TV programs. Currrently these TVs are avail in Plasma or LCD screens and there are newer technologies within a few years. The Plasma screens use twice as much energy (electricity) as a LCD screen. It is suggested that the viewing distance to the TV should be 3.5 times the size of the TV screen.

Hope this answers your query.
Get back to me if you have any more questions.

50 INCH HITACHI ULTRAVISION HAS COLOR DIFFERENCE ON EDGE OF SCREEN


Hey, I found this on a blogsite about lcd rear projections....looks like our tv's screens have been burned by the "pillers" that surround the tv when switching from 4:3 to 16:9 or fullscreen... read below, I hope it helps !
cheers!
Vern

Rear projection crt's,the first generation widescreen tv's were notorious for that.Lcd and plasma can have the same problem,but it takes much longer and is not as harsh.Dlp's use tiny mirrors,so it isn't a problem with them.Lcd and plasma tv's should be ok unless you watch them with blck bars on them all the time.
We have lcd monitors at work,and i've seen them after a year with bad burn in.They also run 24 hrs a day 7 days a week with the same display.



GKar posted 2006 Oct 10 15:31 TooLFooL : i have 51" sony rear-projection and those freakin' grey bars burned themselves right into the screen...

I read that to avoid the burning you had to limit your 4:3 viewing time to 15% of total time viewed. (applied to my TV but apparently yours and others as well...great! now they tell you :-x , this applies unless 4:3 aspect was changed to stretched or zoomed...yuck :-x )

This really sucks as a Star Trek/Lexx/Farscape fan as they are mostly 4:3, fortunately the upconvert player/hdmi combo sends a 1080i 16:9 signal to my TV so the effects are drastically reduced by nearly filling the TV without the grey bars or burn in problem without stretch or zoom modes being used. yay! :wink: (default grey bars set to black automatically, apparently grey isn't needed due to screen area covered is sufficient for burn in not to be a problem.)

Burn in LCD HDtv


not really,,burn in is just that,,the phosphors have burned and become discolored..some times you can lessen the difference by playing a pure white picture on the full screen for a long time, but this is really just discoloring the rest of the pixels so the difference is not so noticable

you must not have the correct picture settings in the cable box, as although they are not HD they will still be widescreen, so check both tv and box for picture settings.

Widescreen?


If the programs you are watching are in standard definition they are meant to viewed in 4x3 and the best you can do is stretch them. If they are in HD you need to use the component video inputs or HDMI, then the TV will see you are watching HD and display it in its natural format 16x9. Also some SAT recievers and Cable boxes have thier own size/ratio settings
