Hi All, I have a AE500 and its my first PJ.( Love it to bits ) I have had it for around 5 months and I just started to notice that when the pj is showing a black screen. There are 2 small round slightly lighter patchs that are visable. When theres colour on those points you can't see a thing. I guess it could be dust but I wanted some advice before I started taking my pj apart or contacting Panasonic. Cheers, GB.
