Hi there, Mona            -

 

Thank you for writing in to the Lenovo Forum - happy to have you here today.

 

This has been commonly linked to a faulty connection somewhere along the LCD cable (connections/cable itself):

 

If you notice the flickering resolving itself after flexing the screen (lightly) or that the problem only occurs in certain orientations then you are likely experiencing a wiring issue.

 

If the screen only flickers at the start screen then it is possible that your drivers are out of date and you will want to update those before continuing

 

Does flickering occurs with external display & in safe mode? Try updating the video drivers.

 

Nvidia 64bit Win 10

 

Update us how it goes.

 

 

 

 

Regards,

well, thanks for replying

I tried to make the updates you mentioned but the problem is still there . and in any re-orientation of the screen, the flickering became slightly less or more so I think it's a wire issue , so how it can be fixed?

Please go through this HMM for better understanding on hardware. It gives the clear guidance about the lcd cable removal. ( Page 72 & 77 )

 

However, if system is in warranty i would suggest you visit the nearest Lenovo service centres for better assistance. Schedule a Call-back for faster support.

 

Update us how it goes.

well , thanks for replying again

I tried a BIOS update two days ago and the black flickering has appeared for just one time then completely disappeared but a white flickering began to appear, but not alot of times like the black , Is that assure that it is a wiring issue? .the system became out of warranty lately unfortunately so I think I will try to fix the wiring issue by myself but I want to make sure it is a wiring issue before I do that .

Note:- I had bought a laptop of the same type y5070 and had the same problem after a week of a moderate using and the service support center replaced it for me with the laptop I have but the problem appeared in that too but after several monthes!
