Why is the blacklight not working after screen replacement?
I have a Toshiba R950 with a faulty LED blacklight. The screen is very dark and you can see text when you use a strong light. So it is a blacklight problem. I have ordered a screen from china, with a higher resolution, but same 40 pin and almost the same screen model number. The blacklight was working, but the screen was green and blurry. I swapped the china screen with the old one, the old one has still no blacklight. After swapping once again, the china screen also has no blacklight anymore! I have ordered the same screen as the original from the Netherlands, but it has also no blacklight. So I have 3 screens with no blacklight. What can be the problem? I think it is maybe the invertor, but that is mounted on the screen, so I don't know.
Thank you in advance.
