Screen is dim/dark picture - Sony Grand WEGA KDP-65WS550 65" Rear Projection HDTV

Depends on the model. Have you checked the backlight, (LED in this set perhaps).

If the picture mode is set to Cinema or Custom, the screen could become dark. If the screen is still dark after the picture quality mode has been changed, change the setting Backlight, Picture, Brightness and adjust the brightness to your taste. ... Depending on such settings, the picture brightness level can be higher or lower

Melissa check you TV's picture settings, cinema, sports, movie, store, etc.and try a different display setting.

I would say either the video cable has disconneted, causeing the led that lights the screen up to not function,, simpley take the bezel around the screen, take the small screws aroud the screen to slightley pull the screen away from the back top to see if the cable is, or has pulled loose...If now the screen is bad..

If you have the same problem with another input such as a DVD player, this TV might need attention by a qualified service technician.

can you help me to sold it.

I have the same problem so far the best I could do was to put the user setting to sports and brighten up the tv as much possible without making the picture look too bad. Good Luck
