Open up the front of the set and find the screen controls and perform a grey scal alighnment by adjusting the red , blue , and green screen controls but be carefull and make sure you adjust them evenly or the picture will not look right. Good Luck

**WORKS**
In my case, the adjustment was available from outside the TV. Sortof.
On the rear of the TVabout 2 inches to the right of the coax in, there
are two vertical slits on a little protrusion. Inside the slits are the
two adjustment screws. The lower screw adjusts brightness, the upper
screw adjusts focus.

How many years is your TV now? Usually TV has its life span, there comes a time that it happens. And need to look for a technicians, cause some of theme can still be repair by adjusting the brightness inside your TV.
SOURCE: TV screen went dark, but sound still there.
your backlight burnt out, this will be a maybe several hundred dollar repair. the screen is backilt by a very expensive flourescent light, without that light, the screen will be black.

I have the AV-27S33 model and in the rear to the right of the inputs are two slits and inside these slits are two screws. The top screw is the focus,the bottom the brightness.Your tv is a different model but it may have this same adjustment,if it does try turning the bottom screw to the right to increase the brightness.
