Does anyone have the solution

Check driver for EL-Backlight. or change lcd.

...or flex cable.

I think most probably is the flex cable, but does anyone have the pic to show the pinout, i think the thread is o/c so need the pic to show me so i can use wire to solder the point

@Shiljo..

When you change the lcd you also change the flex....

Yes,but...flex cable is <10EURO and complete LCD with flex cable is >40EURO and it is very hard to find it...

1-you sure test and replace flat lcd or backlight

2- check the connector board

3-replace or change the (LTYN) IC 100% OK

hi i have same problem no light lcd but i don't want to change flex i want just to know if someone can help me to put 1 wire ..light ways on flex cable....need a chip solution...not expences

change the flex cable. this is the problem(in most of the cases)

Usually changing the flex will fix the problem.

change LTYN
another change flex
