I have a defective switch item , which boots, touscreen is working, keys are working but there is no picture. Water indicator is red but I cannot see any liquid damage.
As everything was working but the LCD I changed the digitizer and LCD with a new one, but still no backlight / no picture.
Now I am running out of ideas where the problem can come from as I was quite sure that with a new LCD it must work
Any ideas what I can do to fix it ?
