Does anybody have any tips for protecting the screen in the first few weeks of use. I have turned the power save option on and have set the contrast, brightness and colour to much lower than the factory settings. Is there anything else I should do? Is it advisable not to watch sky(red dot and logos) for the first x amount of hours. Can anyone also tell me how to get into the service menu. I understand this may have been answered before for plasmas in genral but I cant find anything specific to this screen.
