L440 LCD backlight issue

Hi everyone!


I have a ThinkPad L440. Just out of the box the lcd was very very dark (can see image with a flashlight) no backlight was on. I got a genuine replacement lcd, replaced and still same issue, no change. After that I have upgraded the BIOS to newest - didint help. This is not a driver issue as problem is presistant from start of the pc. External monitor works fine. Any ideas?

Re: L440 LCD backlight issue

Hi Shlapenka,


Welcome to Lenovo Community!


We are sorry to hear that LCD backlight is not working in L440 laptop.


Usually, these symptoms indicate a blown fuse on the motherboard.  The issue comes up frequently when LED-backlight screens are broken.  Lenovo does not do this type of repair (other than motherboard replacement).It can be done, but most places do not have the specialized equipment to diagnose and repair.


I would like to suggest you to visit the authorised Lenovo service centre for the hardware assistance.


Hope this helps. Do post back if issue persists!


Best Regards,
