Y500 Screen Bright White with Vertical Colored Lines

2013-05-22, 21:15 PM

So I purchased a Y500 recently and it has been working mostly fine up until last night. Dual graphics card, i5, 6gb RAM, 1TB HD.


I was doing Excel work in my living room and closed the laptop and carried it to my bedroom. When I reopened the laptop the screen was completely white with vertical colored lines. Sometimes the lines flash around quickly like it's trying to give me epilepsy and sometimes stay in one spot for a moment. 


Ctrl-Alt-Dlt and every other key combination I could think of had no effect so I did a hard reboot. When I turned the computer back on the screen immediately goes back to being white with the vertical lines again. Like almost the instant I turn on the computer. If I leave it on for a while it keeps doing the same thing. I tried leaving it off over night and again in the morning it was the same thing.


I plugged in an HDMI cable to my TV this morning and the computer works through the TV no problem.  When I first booted it up there was a windows update that installed which may or may not mean anything. Once booted up I could use the computer through the TV but the laptop screen stayed white with the lines.


I'm hoping it could be the cable from the GPU to the laptop getting loose but that is pure layman conjecture. The laptop is under warranty so I'd rather not open it up and not be able to fix anything.


Any suggestions?

hi aceec,


     Thank you for using Lenovo Community Forums!


      If your Y500 works fine with an external monitor then this is a display issue.

 Possible LCD cable but normally moving the screen angle like closing and opening the LCD will make the screen flicker.


       Since your still in Warranty I would suggest get in touch with Technical Support for assistance.

 I'm sorry to hear what happened.


Solid Cruver,

Exactly the same problem, but my LCD was changed twice... did help for like two weeks, than the problem started again. That cable to LCD may be the cause, as i tried a lot of testing.
