Idea Pad Y580 display backlight is not working

2017-07-15, 14:37 PM

Hi Everyone!


My display backlights stopped working. I'm still able to see what is on the screen when i put my cellphone flashlight on the screen but it's really hard to see anything. From what I read online it might be just a fuse or the display itself. I was not able to locate the fuse on the motherboard, if someone can help me find the fuse would be great. At first I was thinking of ordering the display but some people changed the display and the problem was still there. Any advise would be appresiated.

P.S. The laptop is already completly dissasembled :)

Hi, Ventsy                   -


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


There were a couple of expert opinions;

  1. it's your inverter (hardware problem)-based on the fact that the screen brightness faded suddenly (but didn’t disappear) and that the screen was not bright on a reboot from before the login screen
  2. it’s a software problem- for which the solution was back everything up and do a reinstall

Kindly contact Lenovo service centres for hardware assistance.
