A1707 no backlight

[Dozer]

Hi, got this A1707 with no backlight, only when open a little bit i can see the display.

so I found here in the Rossmann Wiki this

by the way the black film it can be more clean and easy removed with fine sandpaper instead of scratching with the knife

I tryed that and I have Display now but it looks like every second LED on the bottom is only working
Did somebody had that before?

is the problem here the display or a better guess a bad soldering?

It tryed already 2 times with 2 new cables but always the same result

need some help please

Maybe bad solders, or some trace broken on the flex.
Did you test with known good LCD assembly?

Problem solved, there was another crack in the cable, so i connected like in youtube and some jumper wires then from the junction until almost where the cable is coming out of the screen, hell that was a solder trip! ok, but its working now, thanks for help.
