LCD TV Screen Burn In?




Albert Wes


How long would it take for a static image to burn onto the screen? The longest I leave a game paused is 20 minutes, is this okay?


Answer
It's not possible to say for sure, as there are several variables involved, but I'm confident 20 minutes is safe. CRT-based screens were prone to "image burn" by a single image, especially one with intense brightness, color, and contrast, which is what gave rise to "screen savers". But LCD screens (both LED and CCFL) can be affected by "image persistence" (and Plasma has a stronger reputation for this). The good news is that it is less likely on these screens, and more easily reversed if it does occur. See here for more info:

http://en.wikipedia.org/wiki/Image_persistence and here:
http://www.practical-home-theater-guide.com/image-sticking.html

Some people have even reported a slight image problem from "letterbox" (black bars at top/bottom) or "pillar" (black bar on both sides) effects from playing video with aspect ratios that don't match the screen, but this is likely very rare.
The "Best Practice" is to avoid leaving a white cursor, for example, or a part of an image that never changes for an "extended period of time". Even Wikipedia is purposely vague about this duration, since it depends on things like the nature of the signals, the specific properties of the individual screen, etc.
Then, if you should run into a problem, use a solid white screen for "long duration", or there are videos online that will help return the set to normal, like this:

It's 9 hours long and is just a full-screen color that changes to "exercise" each pixel. There are others - search [video to fix image retention on lcd] - or just turn the thing off for a day... Hope this helps - good luck!

How to fix burn in in a led tv?

My sony 3d led tv's got a long line of burn in on the left side, I tried to clean it with led screen cleaning solution but no luck. Is there any way that I can fix this?, thanks


Answer
What you have is dead pixel and not burn in. I have never had any luck buying any Sony products at all. I purchase a 32" CRT tv in the 90's and that only lasted less than 3 years, then the first HDTV in the market a 34" HDTV from Sony. That also did not last more than 3 years. 2 DVD players when they first came out model 7000 and 7700 both at over $1,100 each and that also did not last over 3 years. They do not have a very good customer service support, they will just refer you to an authorized repair shop. If you read yahoo questions, you can read many problems from other customer with Sony product problems. My first Plasma tv from Pioneer purchased in 2002 is still running. Also have 4 other Panasonic Plasma tv and no problems. First generation blu ray disc player from Panasonic which is now over 4 years old and played over 300 blu ray disc movies without any problems. You may try calling or email Sony and see what they say. Hope this will help you out.
