I just installed a NEC 50XM3/A Plasma. Any image that i put up on the Plasma will still be visable even after I turn the Image off. I know that this will usually happed if one picture is left on for a long period but it is happening here from images that are only on for about 10 seconds. I will turn on my dvd player and it takes me to a startup page. I turn off the DVD player and there is still an trace of the startup screen. I talked to NEC and they said that there have not been any complaints. Has anyone else noticed this problem on the 50XM3/A or should I get it repaired. Thanks for any help
