Laptop screen no display

[gavins38]

I've got a Fujitsu Siemens Amillo LI1718 which had a broken screen. I replaced the screen and all was fine when I tested it, however a few days later the laptop was returned to me and the screen wasn't working. I checked all the connections but they were properly seated, yet still the screen wouldn't display anything. I closed and opened the lid a few times and briefly got the display working. Figuring it wasn't the screen at fault I replaced the power inverter but still no joy. So I had the screen replaced again as I guessed it was faulty. However now I've got another new screen in I still have the same problem. Once again I opened a closed the lid a few times and got the display to work briefly, so I know that the screen does work.

 

I've tested the laptop's vga output and this works fine, so it doesn't appear to be a graphics card fault. I thought it might be the switch that detects the lid is closed on the laptop but as the vga output seems to be working even when the laptop screen isn't, I can't see that to be the problem. That only leaves me with the possibility of something shorting out the screen.

 

I'm getting really frustrated by this now. Does anyone have any other suggestions I can try?

I've seen/repaired a few laptops where the cable between the laptop and screen has become damaged through repeated bending of the cable as the lid opens and closes.

Any idea where I might be able to get hold of a replacement cable and what it's proper name is so I look for the right thing? So far not getting the right matches searching ebay.

These cables are called: LCD screen cable

I have found one on ebay as "Make Offer" item number 170449911689

 

All the best!
