Y50-70 - Sudden blackscreen (backlight + Windows still works)



I got a Y50-70 with a intel Core i7 and a GTX960.


Well I bought it last year and since some months my display gets randomly black. Windows is still running and I can use it with an external monitor with no problems. I think it is either a GPU problem or a dispaly problem


I did a lot of troubleshoot and installed Win8/Win8.1 and Win10 more than 10 times. With drivers, without any drivers, no solution yet.


To fix the problem I always set my laptop into standby mode and then turned back. The screen normally works after that but after some time it happens another time. Sometimes I observed that the screen gets back to its normal status after some time but I can´t say it for sure.


I saw a thread that it might be the "screen-inverter". Don´t know what it is and what it does but maybe it helps for a faster solution.



The only reason that I didnt send my laptop to Lenovo is that I need it for my university.

Hi fixme4 , 


Welcome to the Community Forums. 


Since you still have a viewable screen , best to back up everything that you need. 

As the case maybe similar to this post and that it may be a hardware issue :

While hardware could be the cause in some cases, Lenovo has also determined that these symptoms may also be caused by downlevel BIOS.  Please see this tip from Lenovo - it is in the process of being updated to also include recommendations to update the Video driver and to make a setting change. "


On other cases , rolling back the drivers did help.


Before proceeding with anything I would suggest calling technical support specially if you have previously called in to report this before the warranty got expired and check for other options.


Update us how it goes.
