No Contrast, Display is too bright but not white
I got two 3G both had an moisture damage (red indicator). In one, the display was defective (backlight). I have both 3g equipped with new LCDs (which works perfect in another 3g).
But in those two 3g the Diplays are much too bright and have no contrast = black turns to light gray.
What could this be?
I have cleaned both LCP FPC connectors with a glass fiber pen. No more visible corrosion deposits on it. Do the same below the metal shielding.
The boards were not completly in an isopropanol bath but partially cleaned with ISO .... would be an option.
Does anyone know the exact pin assignment of the LCD connector? Could then search more specific....
Is this a good question?
