I have had my new panny ST50 for 2 months now and am paranoid that i have screen burn from the sky menu. I notice when a white image is shown that there are horizontal lines that show like the dirty screen effect only horizontally. they seem to be most noticeable in the centre of the screen Just recently though i thought what if it's the lines from the sky epg i try to look for it and can't see the image that the epg would leave but is it possible that some of it would get burned in i.e. the lines and not the circle buttons for planner etc. or am i right in thinking that the whole epg would be burned in? What's is the best way to show if you have screen burn? If it is the sky menu i had a thought can anyone tell me if this will work If i go into a mode i don't use say Game and reduce all the settings like contrast brightness to 0 and then when i want to use the sky menu go into game would that eliminate or greatly reduce IR?
