I need help, and my laptop is still working, you can still turn it on, but the screen is only black. That came suddenly at some point. Can you fix this on your own, or do you have to go to a technician / repairer?
Can you fix it alone? The only question is whether you have what it takes
If you tell me what I need for that, I'll have a look.
The appropriate tool, if necessary a new display, a bit of manual skill. YouTube really helps a lot, you can't really say what you need for your laptop without knowing what it is.
"Repairer" or technician.
