I've been concerned, but not particularly worried. However, today my daughter was playing Mario Cart on the TV and finished the game but left it running approx. 30 min on a stationary game screen. When I switched back to cable TV, it was immediately obvious that several Mario game features are burned-in and prominently visible even with prime-time television programs playing. I've turned off to let it cool, hoping that might help, but so far no luck. Needless to say, I hope it goes away while I'm sleeping tonight. If you think LCDs can't get burn-in, call me in the morning as I may have a nice 42" Sharp to sell you.

I have put 140 hours of a modern game on my new Sharp Aquos 60" (used as another monitor)over the last 2 months and it shows no sign of image retention. In the last 10 years none of my business's LCDs have ever shown any image retention. All of the above monitors use no screen saver, are run at least 8 hours with the same image per day (some times much more than that) and are, occasionally, tested by changing the image to display test patterns, movies, videos, etc. Tests by reputible labs can not reproduce image retention in LCDs. In phospher based screens (CRTs and Plasmas) the phosphers can age unevenly (with newer phospher mixes of today one would have to use the screen in a low res mode with borders or as a computer monitor for a long time to "burn" it) causing retention (that's why there is no such thing as a plasma computer monitor). LCDs have no phosphers. It is a myth that LCDs can exhibit image retention and an image displayed for a long period of time can not damage a LCD. It would take other factors to damage the LCD to a point of the pixels not relaxing. LCD image retention is a myth. Plasma image retention is a fact and one must break in the plasma, and then be careful, or certainly retention will happen (which can be cleared although it takes a lot of time and electricity). One would have to abuse a plasma (buy running the same image too long) to "burn" a plasma. The difference between "retention" and "burn" is that the "retained" image can be cleared by ageing (running other images) the adjacent phospers (although that can take a long time and lot of electricity). The "burned" image is where the phosphers are so far aged over the adjacent pixels that they are significantly closer to the end of their life (phosphers slowly lose their ability to glow), they can not glow at the same level as the "younger" (less used) pixels, thus the ghost (retained)image can not be cleared (and is now burned). With the advent of LED backlighting for LCDs (and soon organic LEDs) the contrast of the LCD is now as good as the plasma. Plasma sales will continue to fall off as phospher based technology fails to keep pace with LED LCD, OLED, Parallax LCD, and eventually laser. If you are thinking of buying a flat panel, the LED LCD now has a a pictue better than a plasma as LED has a longer life span, far less heat and energy used, is immune to image retention/burn in, and is equal in contrast ratios and color reproduction. In the past Plasma has always been better for picture quality, however, that is no longer true.

I feel like I wasted $1200. New technology isn't always so great. I called support and they had me turn it off and drain all power by holding in the power button with the TV turned off but problem is still there. Burn-in or retention - LCD is no better than plasma from my perspective. I still have permanent image issues on my display that will not go away. The longest I have left the TV on is for 12 hours.

Nothing will make it go away. It came in one 5 hour period of leaving my tv on with the pc displayed. Now the menu bar at the top is always there as well as an entire image of a website. None of the things stated(white noise-white,black screen left on for some time,nor powering off for days will take it out. It's just ruined! LCD's GET BURNT!!!!

LCD's do have image retention - they have "memory" so to speak. Crystals (LCD...hello?) have been used for decades in one form or another for that purpose. Yes, given time, an LCD will "generally" become neutral again. The time could take hours or...years. The only technology I know of that can have "stuck" pixels is DLP. Plasmas, as CRT based TV's have premature phospor aging. Thence the origination of the turm "burn". Why burn - because it looks like that. They all have their good points and bad points. I would worry less about image retention and more if they have a warranty, service and parts. Kurt Good lord! The HD Guru was simply using a “generic”, commonly used term however inaccurate it is.
