Dark screen/picture. My TV screen/picture faded to dark and the picture menu has no affect on brightness, color or contrast. I can see the picture but it is very dark.

This 30" flat screen TV set may have a problem in the high voltage circuit of the TV set. You may be able to adjust this by taking off the back of the TV set. Look for the block where the large red wire runs up to the top of the picture tube. On this block will be two controls. one will say screen and one will say focus. Try and slowly turn the control that says screen or S on it clockwise and see if you can make the picture brighter. Turn up the control till you just start to see faint lines in the picture, then back the control down till the lines go away. If the picture does not come up when you turn this up, and all you get is a blank screen, you will need to have this set repaired by a qualified repair person. Good Luck
