My monitor starts up properly but the brightness is too low and there is no red,green and blue drive to adjust my brightness.how do i go about it.DEL
It may be a blown backlight. if the image is very very faint, then the backlight has most likely blown. lcdpart.com can get you a new backight, but the replacement will have to be done through a local repair shop.
This icon indicates the BRIGHTNESS control, more properly called
BLACK LEVEL. It adds or subtracts an offset, or bias, into the red,
green, and blue signals. This control should be adjusted so that black
picture content displays as true black on your monitor. Misadjustment of
this control is the most common problem of poor quality picture
reproduction on computer monitors, video monitors, and television sets.
Later in this document, I will explain how to set this control
properly. The setting is somewhat dependent upon ambient light. Modern
display equipment is sufficiently stable that frequent adjustment is
unnecessary.
This icon indicates
the CONTRAST control, preferably called PICTURE. It applies
a scale factor (gain) to the red, green, and blue signals. It affects
the luminance (proportional to intensity) that is reproduced for
a full white input signal. Once BRIGHTNESS is set
correctly, CONTRAST should be set for comfortable viewing
