Backlight????

I just replaced my old broken LCD screen for the mda and installed the new one. The screen works and so does the touch screen but there is no backlight and settings are on for backlight... Whats wrong??? Please help..
I haven't opened the MDA so I'm not sure what the cabling is like (to know if it is a separate cable that controls the backlight or not, if so then this might be inaccurate)...
Sounds to me like the LCD has a dead backlight. Was it purchased used or new? and where from? meaning was the dealer reputable. If so, contact the dealer and ask them for a replacement. As, at least on laptops and most (though not all) electronics, the backlight is integrated into the LCD housing and sold as a single unit. So a failure of the backlight, though replaceable, usually results in the replacement of the screen as a whole.
The LCD was purchased new and came in packaging and had the plastic still on touch screen. Purchased it online. The screen works fine its just the backlight. you might be right about the dead backlight I'll contact dealer and tell them. Thanks
MDA Backlight issue
I ran across a problem with the MDA, where I adjusted the Backlight settings. From there on the Backlight woulf not turn on unless I went to the setting control to adjust it. The fix: Go to backlight settings, set your brightness desired (maybe in the middle). Go to Battery power from the tabs that are currently listed. Make sure you have (Turn on Backlight when a button is pressed or the screen is tapped) Selected. Then press ok.
That should fix it if the issue you are experiencing is similar to mine.
i tried the settings and no good..Is there anything else I should try? Please help.
