I was told there was a way to fix screen burn within the menu, supposedly there is a feature that cleans the screen. How do I do this. Thanks David


Hi there,

Unfortunately there isn't a menu feature for this on LG LCD tvs..there is on LG plasma tvs. Screen burn is the fate of plasma tvs which is phosphur burn, whereas IMAGE RETENTION is the problem on LCDs after prolonged static image displayed caused by prolonged cell charge polarization.
What you could do is connect your PC monitor output to your TV serial input:
Create an image that all is white on your PC. Open Paint and create a big size screen and save it as JPEG.Right click on your desktop>properties>screen saver tab. Choose my picture slide show> the settings>browse the picture you made and modify any settings your prefer your your screen saver.
Hope this helps

I turned on the self cleaning and the door locked but is the heat supposed to go on and off


Yes. It is maintaining a temperature hot enough to burn off residue but not overheat and burn the house down. It should be running somewhere around 500 degrees f

Screen burn in will only occur if you keep the same image for an extended period of time. This can be cleared if you send a pure white image to the set until the "burn" is cleared. In normal home usage, burnin is not a problem unless the set is used for gaming all day. No manufacturer will replace a panel due to burnin. Burnin should not be a consideration when selecting a set.

Image retention


most manufactures say not to have a still image on the screen for more than 15% of your viewing time. to fix this you will have to replace the optical assy. i did come across a sony projection where the burn in was actually on the screens themselves. the only thing you can try is to put an all white video pattern on your tv for at least 48 hrs.

I did have th Tv on pixal shift . Know my screen seams grainy in dark scenes . I does seem a little better after a rolling picture screen. How long do need to run the screen before it gets better?
