I will try to explain again:
If I look directly on the LCD screen then I only see a white screen. But if I look at the LCD screen via the touch screen (that is - I put the LCD off the touch screen) then I do see a display and not just a white screen. Between touch screen to the LCD screen was a bit liquid I had not known what it is and cleaned it. The problem is that right now even though I put on the touch screen the LCD and see display, the display is very weak. Why only when I look at the LCD via the touch screen I see display? Why when I look at it (on the LCD) directly I do not see a display only a white screen? Why after I separated the LCD and touch screen and then put them back together the display is weak?
