I have a slight image burn in that is barely noitcable on my plasma screen. Ive tried leaving the tv on while playing Finding nemo on repeat (for about 4 hours) and it hasnt gotten rid of it. Ive also used the tv constantly for about a month now and its still there. Its really annoying. I wanted to now if anyone has had it repaired and how much you were charged. Thanks!!

Try to display an all white picture for 3-5 minutes.
This is the only way to reduce and possibly remove image retention.

There is no repair for burn in. Burn in happens when you have one channel with a fixed image (or video games which is why they say do NOT use them on the big screens) for a long time and it will burn into the screen.
We have had customers come in and complain because they can't get rid of the little shopping channel logo at the bottom right of the screen.

This explanation from Wikipedia explains it:

Causes of burn-in
With phosphor-based electronic displays (including cathode-ray type computer monitors and plasma displays), the prolonged display of a menu bar or other graphical elements over time can create a permanent ghost-like image of these objects. This is due to the fact that the phosphor compounds which emit the light lose their luminosity with use. As a result, when certain areas of the display are used more frequently than others, over time the lower luminosity areas become visible to the naked eye and the result is called burn-in. While a ghost image is the most noticeable effect, a more common result is that the image quality will continuously and gradually decline as luminosity variations develop over time... resulting in a "muddy" looking picture image.

The burn-in problem can become even more pronounced with plasma displays because of the discrete nature of the pixel elements. Some display manufacturers include image rotation or other mechanisms to reduce the rate of burn-in. One manufacturer has introduced a technology called ZeroBurn(R) which can eliminate it altogether.

Plasma displays also exhibit another image retention issue which is sometimes confused with burn-in damage. In this mode, when a group of pixels are run at high brightness (when displaying white, for example) for an extended period of time, a charge build-up in the pixel structure occurs and a ghost image can be seen. However, unlike burn-in, this charge build-up is transient and self corrects after the display has been powered off for a long enough period of time, or after running random broadcast TV type content.

LCD type displays exhibit a similar phenomenon, although the mechanics of the image retention are different. In the case of LCD displays the liquid crystal molecules, which rotate when energized and allow the white backlight to pass through the color membrane, lose their rotation elasticity. In this case they are unable to fully return to their normal rotation state when de-energized. As in the case with plasma displays, this is usually transient and will self correct after a period of off time or dynamic content. However, in severe cases it can become permanent. Also see: LCD image persistence.

Good luck with your TV.

There is a fix for every burn in and image retention.

For plasma, to replace the plasma panel.

For LCD, sometimes running a color program will reduce it and or replace the panel..

You can take your plasma down to a tv repair shop to run a White washing on your plasma to help reduce the appearence of the burn in. In some cases is has removed it.

Bad news....image burn on a plasma TV is not repairable. This is one of the downsides to this technology. You need to be careful not to leave your TV on with a fixed image for a long period of time, or it will burn. Also, avoid watching programs that pastes bars on the top or sides of your screen to display. These bars will become burned into your screen.

For you next TV, I suggest you look at LED or LCD technologies. They may not be quite as bright, but they don't burn.
