Hi All, I have a Samsung PS50C7HDX tv which has a fussy picture, when there is a dark sceen on the picture there are hundreds of tiny white dots all over the screen. If you turn a tv on with no inputs used you get the black and white fussy picture its just like that in the picture, the tv is still watchable. It also looks like the screen is lighter in the first 1/4 (left to right) then darker then lighter then dark again in the last 1/4! Any ideas? im happy to do some investigation work if anyone can tell me where to look and what to look for. cheers.
