Hi everyone,

I had an old sony vaio laptop with a broken screen so decided to get a new one from eBay. First, the one they sent was faulty because it had a mark on the screen, so I sent it back. But the screen did turn on and work. When I got the new one nothing showed up on the screen at all. I plugged in the original broken screen (which normally showed some lines and marks) but still nothing. When I plug in an external monitor it works fine. On both the old broken screen and the new one, not even the backlight would come on. I shined my phone light on the screen and it showed the VAIO logo and window logo when the laptop boots, but then it goes blank.

When I go into the setting to make sure the laptop screen isn't just disabled, its set to "duplicate screen".

Also, the laptop is running a clean install of Windows 10. It originally ran Windows 7. I don't know if that makes any difference.

I've tried to update drivers in the device manager too, but that hasn't worked.

I would appreciate any help,

Adam

Hi

When you see the VAIO logo and window logo with your phone light, it's because the screen's back lights must be replaced.

Explain: "there is something on the screen." If it's writing in green, it does not need a back light because it's led. HTML and Windows need back lights.

Software has nothing to do with a screen or monitor.

I suggest that you have purchased another screen faulty back light . (Why would one find laptop screens on eBay, why not the entire laptop)

after resetting the pc, everything is showing on the screen. But still no backlight. I don't think it's the screens problem because both screens aren't working. Could it be the cable connecting the screen to the motherboard? If so, is there a way I can check that that's the problem?

Yes it could very well be, but without having my hands on the machine I cannot tell.

I suggest a quick walk to a repair shop.

Good luck and God Save the Queen.

Fixed it finally. Turns out the fuse for the backlight was blown. I used a really small wire to bridge the fuse and it works perfectly now.
