Y700 / Ideapad 15ISK / screen is dead. ideas?

2018-06-27, 15:45 PM

hi there,

 

when i came back from 3 week holidays i found my laptop with a black screen. (yes it was running 3 weeks nonstop)

GPU seems okay since i could access via remote and HDMI but the screen stays black.

 

Even after restart it would not even display a bios notice or the password request.

 

Can this be repaired? Maybe some temporary defect or i need to change the screen? i cannot even fire up the machine because i setup bios password but cannot see the password prompt....

Solved! See the solution

Hi MadBlox,

 

Welcome to the Community Forums.

 

BIOS may only be displayed through the laptop LCD but not with an external monitor. This isolates the LCD issue as you have tested it either remotely or with HDMI connected.

 

Usually, reseating the LCD cable is the first thing to try before testing a different cable or LCD panel and even LCD ports. You can use the hardware manual available at support.lenovo.com under documentation for the guide.

 

I hope this helps answer your query.

 

Regards

Hi there and thanks for the quick reply,

with a very bright flashlight i realized the backlight was not working but the screen was.

After loosing the display screws, fiddling with the cable AND pressing the Backlight-Button on the keyboard the screen went back to life.

 

The key did not work before so i guess it was the cable in the end.

 

Or the screen did heal itself from the 3-week-afk-session without me realizing.

 

Topic seems done, thanks :-)

 

PS:

there is no way to connect 2 external screen using only one HDMI port right? i have to add another GPU right?
