T100 Colour Screen backlight is dead!! :o(

I believe that this phone had been dropped.
OK the phone IS locked to orange, but can be used to make calls fine.
The outside LCD is ok, the Inside LCD works if you hold it near a light to see it. It's just the backlight on the inside LCD that does not work. Any ideas / suggestions what I should check?????

Open The Flip Pannel And Press Each Conponent With A Small Screw Driver When You Get The Correct Conponent It Will Come On Iv Done 3 T100's With Same Problem When You Find The Problem Just Re Soler It With A 15/18 Watt Iron
